CHARACTERISTICS OF THE 309 FUEL EXAMINATION FACILITY

EXECUTIVE SUMMARY

The Fuel Examination Facility (FEF), located inside the Plutonium Recycle Test

Reactor (PRTR) containment has been characterized in order to meet 309 Building needs for

transition to the Environmental Restoration Contractor. The assessment concludes that the

FEF is stable and does not appear to be changing. Additional stabilization work inside the

FEF is not needed to meet facility transition requirements. Minor work is required in

plugging a drain into B-Cell sump from FEF.

In a period of 10 to 20 years radiological conditions will allow for additional cleanout

of the facility with low worker radiological exposure. The peak dose in the FEF is 6.7 Whr

from an activated PRTR shim rod assembly, which contains an estimated 0.9 Ci of Corn.

Dose from the 23.3 pCi total smearable contamination is negligible in comparison. The

smearable content is 99.9% betalgamma. Neutron counts inside the FEF are consistent with

background, implying no transuranic (TRU) material. The shim rod assembly did have an

estimated 48 pCi of smearable TRU.

Lead (est. 2,680 kg {5,910 lbs}) in the FEF is the only known regulated material.

Lubricating oils in the fuel manipulator may also be regulated. Air quality in the cell was

found to be near normal.

The FEF Cell remains essentially the same as when it was operational, except for

some removed equipment. FEF equipment which was original on the containment floor and

in the B-Cell have been removed. The main FEF control console outside the cell is

completely removed. The periscope viewing equipment is gone. Ventilation equipment is no

longer operable, external fans and ducting has been removed. Lighting equipment is intact,

but is not powered. Cooling water sprays headers have no water supply, and the B-Cell

sump pump has been removed. The fuel manipulator appears to be intact, as well as the

water spray risers and the lighting banks. Mounted in the manipulator is a portion of a

PRTR Shim Rod Assembly. Observations show the cell has a dried material on the floor.

Among the equipment is the fuel manipulator and its associated cooling ducting. Also seen

are portion of the wide angle viewer; and a small instrument package.

CHARACTERISTICS O F THE 309 FUEL EXAMINATION FACILITY

1. INTRODUCTION

The 309 Building has been declared surplus and is in the transition process to surveillance and maintenance, pending ultimate decontamination and decommissioning. transition process requires that existing conditions be identified and stabilization performed. Transition requirements are identified by the facility Transition requirements checksheets (WHC-SD-NEL-RD-001). The Fuel Examination Facility (FEF) characterization and stabilization needs are addressed by this document.

The

This report constitutes the final report on the status and condition of the FEF Cell. This report describes the results of the physical, radiological, and chemical characterization of the 309 FEF Cell. The purpose of the report is to document the present status of the FEF cell and its contained equipment. The characterization work is done to provide information to best protect workers, the environment, and provide information for use in future restoration, and cleanup work activities. The characterization work is primarily directed toward determining the Cell content and radiological and chemical conditions.

2. Characterization Process

The FEF characterization process includes: (1) background information search, (2) radiological characterization, (3) chemical characterization, (4) cell equipment identification and condition review, and (5 ) generate FEF Cell status report.

2.1. General Approach and Philosophy

The FEF background information search included a review of 309 drawings, published reports, manuals, construction specifications, radiological survey reports, and certified vendor information.

The radiological conditions in the FEF are determined by monitoring radiation dose rates, gaseous and particulate contamination, smearable contamination levels, and neutron radiation. Dose rate measurements provide an indication of potential exposure and equipment radiological activation. Smearable contamination levels provide release potential information and radiological contamination stability. Neutron radiation measurement provide evidence of transuranics. Air samples quantify the particulate Contamination directly available for release and for controlling personnel exposure.

The chemical characterization identifies hazardous materials and conditions for planning maned entries. For this reason, the cell atmosphere is monitored for oxygen, and visually examined for evidence of chemicals or oils.

A video search of the cell is made to identify equipment, assess structural conditions and look for chemical indications. Remote video equipment is used to record and monitor conditions. Video provides easy access for observation and isolation from radiation. A video survey establishes what equipment is installed and an indication of the physical conditiodstatus of the cell and equipment. Pictures are easily obtained from video tape and can readily be include in reports.

2.2. Work Description I The FEF field work characterization procedures are given in Work Package

3B-96-00144. Process highlights and difficulties are presented below.

Access into the FEF may be achieved from the containment floor by removing plugs or cover blocks, and from the shield door in B-Cell at the -32 ft. level. Entry through a plug in the cover blocks was selected for the initial entry. This provided easy access and minimized radiological exposures potential.

The first step was to expose access plugs and attach rigging equipment. A layer of sheet metal was removed. The sheet metal provided protection to the painted floor when the containment was used as a shop. Next paint and a material resembling an epoxy grout were removed from around several access plugs. The plug drop anchors were exposed and cleaned. A radiological control area was then set up around the work area.

Cell entry was attempted through five separate plugs. The Fuel Access Plug (center plug) was pulled first, since it was the plug normal entry during operations. Full cell access was blocked by the fuel examination manipulator and a peace of equipment identified as a part of a PRTR Shim Rod Assembly. Attempts to lift plugs on either side of the fuel Access Plug were not successful. The Viewing Plug was them removed, providing a triangular access area which was open to the FEF floor. The accessible FEF area was bounded by the lighting fixture in each of the northern comers and the fuel handling machine mounted on the cell south wall. Sufficient access was provided, eliminating the need for entry at the -32 ft level.

measurements were made at the opening and at 30.5 cm (one Ft.) increments. An air sample was obtained to determine airborne contamination. Air quality measurements were made for explosive gases and oxygen level. A remote operated video camera was used to observe and record conditions and equipment inside the cell. Smear samples were taken from representative surfaces and equipment in the cell. A six meter telescoping pole was used to reach down into the cell and take smears from equipment and walls. Floor samples were obtained from material on the protective sleeving placed around radiological instrumentation, which was scraped across the cell floor. A standard sue smear was taken, read by the RCTs, and the results recorded. Smear samples were analyzed by the PNNL Analytical Chemistry Laboratory, located in the 325 building. Sampling and analysis result are located

Sampling was performed through the view plug opening. Radiological dose rate

Following a review of the data the FEF was reentered and the radiological dose rate measurements at 30.5 cm increments repeated. The instrument used was not responding correctly to conditions above 800 mR/hr. While the FEF was open a neutron counter was also inserted and measurements taken a three levels. Neutron data were analyzed by PNNL NDA System personnel.

After all data was gathered the viewing plug was replaced. The temporary radiation area was surveyed and dismantled. The FEF was left in a state to easily access the view plug in the future.

3. CELL AND EQUIPMENT BACKGROUND

3.1. Facility History

The original 309 building mission was to provide an operating test reactor in the Hanford Engineer Works (HEW) Plutonium Fuels Utilization Program whose purpose was to research and develop nuclear fuel technology. This test reactor was known as the Plutonium Recycle Test Reactor (PRTR). A General Layout of the facility and it's various features are shown in Figure 1.

In 1963, Fuel Element Rupture Test Facility, (hereafter called the Rupture Loop) operations began in one channel of the PRTR. The Rupture Loop itself was a pressurized, light-water-cooled loop within the main, heavy-water-cooled PRTR. The Rupture Loop was used as a pilot irradiation facility to test new fuel element designs and new operating regimes. Many of its tests involved pre-defecting fuel elements with pinhole breaks to study the stability of various pre-defected materials under irradiation. The FEF was used to examine fuel from the rupture loop as well as the PRTR.

Such Rupture Loop tests continued until a serious (Type A) operating accident occurred on September 29, 1965 (fuel rod failure). After the subsequent cleanup, the PRTR resumed critical experiments, known as the Batch Core Experiment. This experiment ran for only about half of its planned duration before a flaw was discovered in the P-4 valve (the main valve in the primary coolant inlet system). The PRTR was shut down in order to replace the valve in early 1969. The U.S. Atomic Energy Commission (AEC) decided not to refuel the PRTR. The PRTR was laid away in 1969 and subsequently decommissioned. By 1975 the PRTR had been deactivated, all fuel removed and the fuel storage basin decontaminated.

In the late 1970's, the ground floor level inside the PRTR containment dome was emptied and converted into a "clean shop" (i.e., one using no radioactive materials and no sodium) to fabricate sodium test loops used in the 324, 335 and 337 buildings. This conversion removed the fuel handling machine and FEF control equipment at the 0 Ft. level.

In 1986-87 a space technology development program known as SP-100 was assigned to the 309 Building. This program immediately undertook an extensive clean-out of the PRTR facilities in the building. The clean-out included removal of all PRTR process equipment from the containment floor, A, B, and C cells. Among the equipment removed were the FEF ventilation and cooling equipment and the B Cell sump pump equipment.

In 1991, the SP-100 program was placed on a 5-yr "hold," thus ceasing any further clean-out. The SP-100 program was terminated by DOE in November 1993, which has brought about the transition of the facility.

3.2. Fuel Examination Facility Description

The FEF cell was an experimental hot cell used to exam PRTR fuel and process tubes. The FEF functioned as a hot cell where personnel conducted remote manipulation of fuel elements or process tubes. The FEF was used for making observations, preliminary gamma scans, and other tests on irradiated and sometimes breached fuel. (Gerber, 1992) The type of fuel characteristics studied included: warpage, swelling, cladding anomalies, and other defects.

The FEF physical description and equipment are described below. The general layout and configuration is depicted in Figure 2 through 6. A more detailed FEF description, operation and maintenance requirements are found in the FEF Operating Manual (Kelly, 1961). The construction specification is HWS-6340.

3.2.1. Physical Description

The FEF Cell is located inside containment in the radial wall between B-Cell and A- Cell. A control console for the facility was located on the ground floor level of the containment dome (north side). Ventilation supply and exhaust equipment, process water connection, drain equipment and cell access were in B-Cell.

Air was normally for cooling sample, provided by the FEF heating and ventilation system. But, the cell also contained a vertical set of water spray riser units that served two purposes, back up cooling or cell decontamination and cell wash down. The cell contains a 10 cm (4 in.) floor drain, discharging into the B-Cell sump. In the B-Cell sump were a solenoid valve and pump, operated from the control console. This equipment removed waste water to the 309 Tank Farm hold-up tanks. The valve, pump and waste lines in B-Cell have been removed, waste lines capped, and the tank farm shut down.

The FEF Cell viewing and fuel handling equipment were operated from a Control Console. It sat between the containment north wall and FEF shielding blocks. The control console, periscope, fuel handling vehicle, and equipment protruding above the containment floor were removed during facility conversion to the sodium test loop fabrication shop. Portions of the periscopes may still be in the FEF. The control console and wiring into the FEF are removed. The connecting trench is empty, and portions filled with concrete.

The cell is a 1.8 m by 1.2 m by 8.5 m (6 ft by 4 ft by 30 ft) structure with a stainless steel liner. The A-Cell side wall is constructed of 1.1 m (3.5 ft) heavy aggregate (high density) concrete (bulk density 4,325 kg/m3 (270 lbs/fP.) The north and south walls are structural concrete. The B-Cell side wall is constructed of 0.56 m (22 in.) thick, tightly fitting, cast iron blocks (Meehanite). The overall cell is lined with 16 gauge stainless steel. The Cell is covered with three 0.6 m (24-inch) deep shielding plugs, which form portions of the containment floor. A 15 cm (6 in.) vertical steel plate is mounted in the top half of the FEF near the north wall, providing shielding for the periscope and optical viewing equipment.

Access into the cell is through ports, plugs and a door. In the shield plugs are eight 32 cm (12.75 in.) diameter access and equipment plugs. These plugs provided for sample insertion, cell viewing, and cell lighting. A manned entry into the bottom of the cell is provided through a heavy metallic bank vault type door located in B-Cell at the -32 ft level. Observation ports and access plugs are also available at various levels into the side of the cell. Characterization work performed was accomplished through the Sample Access Plug (fuel entry) and the Viewing Plug located in the containment floor (0 foot level).

3.2.2. Principal Equipment

Equipment used for the FEF included sample handling and viewing, and cell support equipment. Sample handling and observation was provided by two remote controlled periscopes, the fueling vehicle, and in cell manipulators. Support equipment included the ventilation and cooling system, two light fixtures, water cooling and decontamination, and liquid drain equipment.

Fuel Manioulator

The manipulator is essentially a 9.1 m (30 foot) long vertical lathe bed with two translatable carriages on each is a mounted a rotatable universal chuck. The manipulator is designed to handle 8.9 cm (3.5 in) cylindrical specimens weighing up to 137 Kg (300 lbs.) The only engineering drawings located for the fuel handling machine were: manipulator assembly, SK-3-1161;, Upper manipulator head SK-3-11509; lower manipulator head SK-3-11511 and SK-3-11508.

The manipulator heads were translated either up or down by electrically driven screws. A PRTR fuel assembly was 4.4 m (14 ft. 5 in.) long, the active core was 2.2 m (7-113 ft.) long, and a shim rod assembly is 7.7 m (15-112 ft) long. Shorter fuel rod lengths were also tested at PRTR, but longer lengths were undoubtedly rare and nothing in the 30 foot range would be expected. The vertical drive motor for the manipulator is listed as a 5 h.p., 3500 rpm, 240 volt D.C., General Electric totally enclosed, non-ventilated piece of equipment. (Additional information is in CVI file No. 15449, portions are in Appendix E.) The chuck motor is a variable 0.5 to 2.0 h.p. 1750 rpm, 72 volt D.C. motor. The equipment was connected to controls outside the cell and is not operational.

11


Ventilation and Cooling EauiDment

There were two ventilation systems, a 0.12 m3/s (250 CFM) and a 0.68 m3/s (1500 CFM) System. The two supply fans and one exhaust fan were located in B-Cell. The smaller system used 4 inch Schedule 40 pipe, and the larger 25.4 cm (10 in.) inside diameter tubing. Ducting into the cell is at the -5.8 ft level. Inside the cell the ventilation systems supplied air through specially designed ducts attached to the fuel manipulator. The 250 CFM system provided axial cooling through the chuck. The 1500 CFM system provided cooling along the length of the sample. The 38 cm (15 in.) inside diameter exhaust duct intake was located in the north cell wall. After passing through a HEPA filter the exhaust entered the containment exhaust system. The B-Cell ventilation equipment has been removed.

In the event of a power failure, reduction of cooling airflow or specimen overheating during FEF operation, water spray cooling was available. The cooling air system was shut off and an automatic water spray rinse system was energized. Water jets were located inside the cell directing coolant onto the sample. The spray cooling was shut off if the water level in the cell reached the -8 ft. level.

Optical EauiDment

Optical equipment used in the FEF included periscopes and a boroscope. Two optical periscopes, operated from the control console, were used for observation, measurement and photographing irradiated specimens. One periscope had a two headed wide angle viewer providing a 70" field view at the -2 ft 6 in level and the -19 ft level. The other periscope was dual purpose providing a 5X magnifier and a profilometer. The prodlometer functioned at the -19 ft level. A boroscope was also used for viewing the inside of process tubes and disassembled elements. The boroscope operated through the fuel element loading plug. The optical equipment outside the cell is no longer present.

4. FEF CELL RADIOLOGICAL CONDITIONS

4.1. Radiation Dose Rates

Measured dose as a function of depth for the FEF Cell is given in Table 1. These values have been plotted and are shown in Figure 7. Note that the graph shows a sharp maximum dose rate value that corresponds to the location of the lower fuel handling chuck mechanism.

The FEF shield plug was effective in eliminating any appreciable dose rate with the FEF closed. A dose rate of 2 mR/hr was measured after the fuel Access Plug was removed in the first characterization attempt. However, hardware that prevented the access port from being useful, probably also kept the dose rate down to 2 mR/hr. Dose rates in the FEF were measured via the fuel Access Plug port. The dose rate values measured from the Access Plug port were later found to be inaccurate above 0.800 mR/hr. The instrument calibration was rechecked and measurements repeated through the view port.

A dose rate of 7 mWhr was measured later when the Viewing Plug was removed. Dose rate values varied with depth up to a maximum of 6700 mFUhr. The depth of the maximum dose rate was about 12 feet. This is in the vicinity of the manipulator lower chuck and the shim rod assembly Inconel shims. Dose rate dropped sharply as the lower in the cell, to roughly 5 mR/hr at the bottom. The Cell has very little equipment in the lower half which probably explains the low dose. The Radiological Survey Reports are provided in Appendix B.

A PRTR shim rod assembly is the primary radiation source. Based upon the shim rod geometry, materials and radiation dose rate profile; the shim rod Corn source is estimated at 0.9 Ci. The shim rod assembly is the principal contributor to the FEF dose.

4.2. Smearable Contamination

Radioactive dose rate and contamination smear results show the FEF cell contamination to be fixed (almost non-smearable). Smearable contamination summaries are presented in Table 2. Samples were taken from the readily accessible surfaces in the FEF, and are representative of the vault conditions. The smears taken were standard 100 cm2 samples. Radiation survey report and assay reports are located in Appendix B.

Radiological contamination smear results listed in Table 2 indicate the highest smear level to be 90,000 dpm. Typical Geiger Muller (GM) beta/gamma instruments used at Hanford exhibit about a 350,000 dpm reading for a 1 mR/hr Cutie Pie (CP) or RO-7 instrument reading. This means the highest smearable contamination reading is less than 0.3 mR/hr compared with the highest dose rate reading of 6,700 Whr. The radioactively contaminated material at the (-)12 foot level of the FEF cell is therefore primarily fixed, it is in an encapsulated form, or not readily accessible.

The greatest source of contamination is the fuel manipulator lower chuck and the surrounding area. Analysis of the smears show high beta and Cow which account in part for the sharp dose rate. Total alpha is comparatively low indicating little or no nuclear fuel residues.

The smearable contamination inventory is estimated at 23.3 pCi total for the FEF. The smearable content is 99.9% beta/gamma. Details for this estimate are presented in Appendix C. The inventory is based upon a surface area estimated and isotopic smear averages for horizontal and vertical surfaces. The surface areas are estimated because detailed component drawings were unavailable, from which exact dimensions could be obtained. Smear samples are expected to be representative of the FEF conditions.

The shim rod assembly, mounted in the manipulator, is the only item with AmB1. AmB1 is a decay product of PuZ4l which indicates a PRTR fuel presents. During PRTR operation the shim assembly was cooled with heavy water. Smearable contamination on the shim rod are comparable to those found in the reactor moderator system (Ref. HNF-SD-ER- 008). Shim Rod estimates surface area is 11,400 cm2 (1,771.40 in’) which will yield the following isotopic estimates: Total Alpha, 7.65 nCi; Total Beta, 18.4 nCi; Corn, 5.28 nCi; Csl”, 13.8 nCi; Am241, 3.15 nCi (For PRTR this is equivalent to 0.297 pg TRU;) Total Ci, 48.2 pCi.

4.3. Neutron Monitoring

Neutron probe measurements were taken to determine if appreciable PRTR reactor fuel is located in the FEF. A neutron probe was lowered into the FEF Cell and measurements were made just above the Cell, the top of the Cell -0.91 m (- 3 ft.), -3.7 m (- 12 ft.), and -5.5 m (-18 ft.). The measurements indicate the neutron count is consistent with background levels. The uncertainty of the measurement supports the claim that less than 0.5 of TRU can be present in the FEF. This number is conservative because of the potential multiple counting of neutrons due to a neutron cavity effect in the FEF. The sample report is located in Appendix B. No fuel was detected in the FEF.

5.1. Oxygen Monitoring

The FEF Cell has not been opened for approximately 25 years. Before entry there was concern that the oxygen level might have decreased, constituting a potential confined space issue. An oxygen monitor no. 9308101-049 using sampling pump no. 9309069-106, calibrated Feb. 4, 1997 was used to monitor the oxygen levels at 5 foot depth intervals on the 2/4/97. Table 3 shows the results, oxygen levels are normal or very nearly normal being 20.9% oxygen versus 20.9 to 21.0% for the reference level measurement.

5.2. Regulated Materials

Materials in the cell which may be potentially regulated include the following.

The FEF structure and components FEF contain an estimated 2,680 kg (5,910 lbs) of lead. See Table 4 for location details and quantities.

During sampling there were indications of oily film on lower manipulator. A repiew of the operations manual and procurement specification provides information on two oils and a grease. A review of the available documentation did not indicate equipment listed nor observed as being hydraulic driven, therefore, no hydraulic oil is expected in the FEF.

There is an oil in upper gear box on the upper drive head and lower drive head fuel handling machine manipulator, the oil used is not stated in the operating manual.

A lubricant was routinely applied to manipulator guide rods. The lubricant is Nuclear Grade Radiation Resistant Grease #335 (NLGI #O Grade) produced by Standard Oil of California 225 Bush Street San Francisco, CA.

0


Each air motor (Gardner-Denver,) spline connected to the chuck jaws, holds approximately 4 lbs of grease. The reference materials did not state what type of grease was used

A small amount of penetrating type oil (Aerokroil) was added with a dropper to the seal plug seams to make it easier to remove the cell plug. The MSDS no. is 10231, residual material is not regulated. There might remain some residual oil on the Access Plug and the Viewing Plug. Oily rags and waste are regulated, but we did not generate any and would not expect there would be sufficient residual oil to generate any regulated waste in the future.

0 Glyptal (MSDS no. 14680) paint on the nuts and bolts that one can see looking back up the cell towards the bottom of the upper chuck in Figure 16.

There is also the Anti-Seize lubricant (MSDS no. 12828) residue on the seal plugs, but none of these (Aerokroil, Glyptal, or Anti-seize) should present any appreciable cleanup problems.

In cell FEF equipment is designed for decontamination with water, solvents (xylene or acetone) or acids (dilute nitric.) However, these materials are not expected to be present. If Water rinse was inadequate the solvents and acids in limited quantities could be used. (Ref. HW-70880 page 26)

5.3. Glyptal

A chemical condition was noticed when the cell was video taped. It was noted that the bolts and nuts were painted with a reddish colored material. Based upon prior experience with similar material the material is Glyptal insulating paint. Glypital was used extensively in the 1960 and 1970’s. The nuts, bolts, fittings, and similar items were painted with Glyptal to inhibit rust and prevent bolted joints from freezing, but, could be easily removed. The MSDS for Glyptal is 14680 (see Appendix D). Glyptal residues are not regulated. Glyptal product and coated rags are regulated due to volatile constituents. The removal of Glyptal treated bolts, nuts, or fittings should not result in the generation of a hazardous or mixed waste.

5.4. Anti-Seize

The Viewing Plug was very difficult to remove initially, requiring approximately 2 tons of force to remove a 660 lb plug. Rust, sand, and other foreign materials were found to be on the outside of the plug. Anti-Seize lubricant (MSDS No 12828) was applied to the outside of the plug to make it easier to remove in the future. The Anti-Seize lubricant residues are not regulated, but the product and rags are regulated similarly. No hazardous or mixed waste was generated in coating the View Plug with Anti-Seize lubricant.

6. FEF CELL VISUAL OBSERVATION

6.1. General Observations

The FEF is stable and in good condition. Equipment in the cell appears to be intact with little or no signs of deterioration. There is a PRTR shim rod assembly mounted in the fuel manipulation machine. A thin layer of dried material is on the FEF floor. A light coating of oil was observed on the fuel manipulator lower chuck. There is very little loose equipment found in the cell. There appears to be some equipment inside the shielded periscope area that was not identified. video tape and a reference listing of archived photographs.

I Appendix A contains pictures captured from the

The port hardware shows indications of rust spots, because of this the viewing plug was lightly coated with an Anti-Seize lubricant (MSDS 12828) before replacing the plug. The bottom section of the plug port was clean as shown in Appendix A Figure 1. As far as working space, the south end of the sample port has limited access due to the Fuel Manipulation Machine and Shim Rod Assembly, but otherwise is clear. Access through the viewing plug provides ready access to the FEF.

6.2. Fuel Manipulation Machine

The first piece of equipment visible in the cell from the view port is the fuel manipulation machine upper chuck. (See Appendix A Figures 2 through 10.) At present the upper chuck is just below the cell block at about the -5 foot level, with the lower chuck at the -16 foot level. A PRTR fuel core was 2.2 m (7-113) ft long, and a shim rod assembly is 7.7 m (15-112 ft) long. Shorter fuel rod lengths were also tested at PRTR, but longer lengths were undoubtedly rare and nothing in the 30 foot range would be expected.

The carriages are translated either up or down by electrically driven screws. The screw drive mechanism for the lower chuck of the fuel handling machine can be observed in Appendix A Figure 10. Hidden behind the center drive is another screw drive which is readily observed. The chuck jaws are spline-coupled to air motor drives shown in Appendix A Figure 10. (SK-3-11512 is an isometric drawing of the air motor.)

6.3. FEF Samples or Specimens

The FEF examination revealed that there was a piece of equipment mounted in the manipulator. Appendix A Figures 13 through Figure 18 show the specimen. People familiar with PRTR operations recognized it as a PRTR Shim Rod Assembly. Neutron monitor established that it was very unlikely there are any appreciable fuel material (fuel pieces) in the FEF Cell.

Shim Rod Assembly drawings are H-3-14913 for a Mark I11 design and H-3-13484 for an earlier design. The actual shim was three 0.9 M (36 in) long Inconel "half rods." (Wittenbrock, 1959) The shims were used to balance the reactor neutron flux by absorbing

21


some of the neutrons, thus changing the neutron flux profile. The shim rods became radioactive (Co-60) in the process and are responsible for the bulk of the FEF cell dose rate. The shim rods are estimated to contain 0.89 Ci of Corn the activated nickel produces an X- Ray.

6.4. FEF Lighting and Cooling

FEF lighting is provided by two vertical fixtures, containing eight flood lights each. The fixtures are located on either sides of the view port. Protection is provided for the flood light bulbs by a ladder like structure. The light fixtures are shown in Appendix A Figures 8, 9 and 13. The light fixture drawing is H-3-11982.

Also, observable in the figures are the two water spray risers adjacent to each light fixture. Appendix A Figure 12 shows a typical spray nozzle. Water spray could be used for washing the FEF down or as back up fuel element cooling.

6.5. FEF Cell Floor

The FEF Cell floor is shown in Appendix A Figures 2 and 3. The FEF floor is easily visible below the lower chuck and light fixture. Magnification of the floor in Appendix A Figure 4 shows a dried solids material. The material appears to be a wash-down residue. These solids were sampled via a contamination smear and were submitted for analysis. Smear contamination levels were low compared with other smear samples. Since radiation dose rates were also low near the bottom, the cell access door in B-Cell could potentially be used for monitoring purposes, or manned entry. Near the floor is an instrument bundle with connecting cable, and two metal plates which appear to have gone around a pipe, such as the floor drain.

6.6. External Observation

Portions of the FEF and related equipment can be visually observed without cell entry. The operational configuration had equipment in the B-Cell and on the containment floor. Drawings for the various parts are as follows: air supply and exhaust, H-3-11975; water cooling and decontamination, H-3-11976; and electrical equipment, H-3-11999.

The process water cooling supply piping in B-Cell has been removed and the pipe entering the cell structure capped (See Appendix A Figure 21 .) exhaust fans, duct, dampers and instrumentation are no longer present. The ducting to and from the cell have been capped. The two duct inlets are visible in Appendix A Figure 20.

The Air Cooling supply and

The FEF control console, external periscope equipment were removed in the 1970’s. along with the control console, electrical power, control cable, and tubing. The south half of the cable trench was filled with concrete. The trench going back into the motor control center is empty.

22


7. CELL STATUS

The FEF Cell remains essentially the same as when it was operational, except for some removed equipment. The main FEF control console outside the cell is completely removed. The periscope viewing equipment is gone, the ventilation equipment is no longer operable, the lighting equipment is intact, but no power is available, the cooling water sprays headers have no water supply, and the B-Cell sump pump has been removed. The FEF utilities have been removed. The fuel handling machine manipulator appears to be intact, as well as the water spray risers and the lighting banks.

Cell Structure - The stainless steel lined cell appears to be in sound condition. The cell walls are all present and all access plugs are in place. No cracks or leaks in the system were apparent. There is smearable low level contamination on the cell walls and cell floor. The cell floor is painted white. The bottom part of the cell is empty except for one peace of instrumentation and connecting cable and some residual dried solids on the floor. The cell door at the -32 ft level is locked and bolted closed. On the door is High Radiation Area posting.

Control ConsolelODtical EauiDment - The control console is no longer present. The FEF control console was located inside containment on the north center side at the 0 ft level. All ties to equipment inside the cell have been removed. The cable trench is empty it contains no pipe tubing or wiring. Portions of the trench have been filled with concrete. This concrete may be why some of access plugs in the containment floor could not be removed.

SamDle - Shim rod Assembly - Portions of a PRTR Shim Rod Assembly are mounted in the manipulator. The shim rod is held in position buy the manipulator chuck. Attached to the top of the shim rod assembly is a fuel handling chuck. This chuck may have been used to insert the shim rod into the cell with the fuel handling machine, (which is no longer present.) The shim rod dose is 6.7 Whr from activated Inconel contains an estimated 0.89 Ci of Corn, and activated nickel which emits X-Rays on decay. The shim rod assembly has smearable contamination similar to the PRTR Primary Cooling system.

.

ManiDulator - The FEF manipulator assembly is in place and undisturbed from the time the PRTR was shut down. There is an oily film on lower manipulator head top surfaces. The film is believed to be from the manipulator gear box and/or guide lubricants.

Oatical Viewing EauiDment - The optical viewing equipment outside the cell has been removed. Inside the FEF the optical equipment was located behind shielding. A video tape review showed one item resting on the lower shelf of the shielded space. The item was not identified but it may be a potion of the optical equipment, perhaps the wide angle viewer.

23


Lighting EauiDment - The two lighting fixtures used in the FEF are present. Eight flood Power and electrical connections to the lights lights are mounted in each assembly.

have been removed.

Cooling EauiDment - The 250 cfm and 1500 cfm air cooling assemblies are present inside the FEF. Interfacing supply and exhaust fans, ducting, dampers and instrumentation which were in B-Cell have been removed (See H-3-11975 for a layout of the original installation.) The ducts have been covered at the cell structure surface (This work was accomplished in 1986 clean-out activates.)

Water SUDD~V and Drain - Cooling water supply to the FEF spray system has been removed (See H-3-11976 for a description of the original installation.) The spray headers inside the FEF are still present. The cooling water pipe in B-Cell have been cut and capped. The containment process water systems have been drained.

The FEF floor drain was connected to equipment in the B-Cell Sump. The pump, valves and pipe were removed during the 1986 clean-out. At present the cell drain pipe extends approximately 7 cm (3 in) into the B-Cell sump, and is not plugged.

8. RECOMMENDATIONS

The FEF is stabile and does not require significant work to meet transition requirements. The only stabilization work needed is to plug the floor drain in B-Cell. Any further equipment removal or deactivation should be delayed until the FEF dose will allow contact handling of the equipment. This is expected to be 10 to 20 years. At that time the fuel manipulator could be removed through the containment floor shield blocks, using methods described in the operating manual. With the manipulator removed the shim rod assembly could be removed. As the FEF is now configured the air motors on the upper and lower carriage can not be opened to remove the shim rod assembly.

Dear Mr. Cornwell:

PNNL DOWN-HOLE ASSAYER RESULTS: FUEL ELEMENT EXAMINATION FACILITY

Enclosed is a s e t of data for work performed on February 24, 1997, using the PNNL Down-Hole Assayer System inside the sample chamber o f the Fuel Element Examination Facil i ty. The assay was performed a t the request of Mr. Wilbur Greenhalgh (decd.) t o provide posit ive confirmation that no fuel elements or fragments were stuck inside the chamber.

The PNNL Down-Hole Assayer System is a nonzdestructive assay (NOA) system that employs high-resolution (HPGe) gama-ray spectrometry and/or passive neutron counting t o characterize a local radiological environment with confined space o r where physical access is restricted. Only the passive neutron counter was deemed necessary f o r achieving the requested radiological characterization.

Aloha-Particle Activitv Measured via Passive Neutron Countinq

The neutron count f o r the PNNL Down-Hole Assay System is performed with a single %F, neutron counting tube with 5-cm diameter and 1.83 m length. The neutron count was taken with a bare tube ( i . e . , no polyethylene wrap t o provide moderation f o r higher energy neutrons i n the source term.)

The neutron tube counts ambient neutrons tha t a re low enough i n energy t o be captured by the %. The counting model assumes two sources of neutrons: one from natural background and one from transuranic (TRU) isotopes. The natural background source of neutrons consists mostly of spallation products caused by cosmic-ray bombardment o f surrounding structures, which i n this case was depressed because of the shielding e f fec ts of the massive concrete overburden. The other source of neutrons is transuranic materials, which has two components associated with i t : 1) alpha-particle ac t iv i ty resu l t s in neutron emissions via (a,n) reactions, predominantly w i t h oxygen and other l igh t elements of the matrix and 2) spontaneous fission of various transuranic isotopes (typically even- numbered isotopes) releases several neutrons.

Appendix B-1 1


6. C . Cornwell Page 2 June 18, 1997

In cases where no process knowledge i s provided o r available, the TRU value determined from the neutron count i s based on the spec i f ic alpha-particle ac t iv i ty of weapons-grade PuO,, a conservative estimate since weapons-grade plutonium yie lds the lowest alpha-particle ac t iv i ty (hence,- the lowest neutron emission ra te ) o f any TRU material t h a t can reasonable be expected i n Hanford waste. T h i s assumption i s appropriate i n t h i s instance because of available process knowledge.

Data were collected a t 3 depths inside the sample chamber t o prof i le the e n t i r e length. Counting intervals were a t 1.8 m, which i s the length of the neutron counting tube used. The tab le sumarizing the upper-limit levels of weapons- grade PuO, a t the 3 depths is presented i n Exhibit 1. Computer printouts from the code NANAL, used t o document the neutron-count data, a re provided i n Appendix A.

Passive Neutron Counter Efficiencv Calibration

Direct efficiency calibrations were previously performed on several the passive neutron counter using the same configuration tha t was used f o r acquiring counts i n the sample chamber o f the Fuel Element Examination Facil i ty. The neutron source used i s the M-710 Z’9Pu6e, whose neutron emission r a t e corresponds t o a 953-9 weapons-grade 2’9Pu0, source. This neutron emission r a t e i s relative t o the PNNL NIST-traceable 100-9 weapons-grade PuO, standard, 196148. Calibration consists of a se r ies of counts with the standard centered on the length of the neutron counting tube, as specified i n the PNNL Technical Procedure SGS-001. A count i s taken w i t h the standard moved back in 1 f t increments. Five such counts were performed as part of the calibration. The resu l t s of the calibration a re provided i n Appendix 6.

The observed passive neutron data and the corresponding efficiency are used i n the PNNL NANAL Neutron Analysis Code t o determine TRU levels or gram-quantity values. The result ing hardcopy outputs a r e enclosed f o r each of the corresponding depths. An a rb i t ra ry net sample weight o f 1 g was used; consequently, the TRU ac t iv i ty ra t ios , expressed as nCi-alg a re a r t i f i c i a l l y high and should be ignored -- the “Total grams of TRU“ portion of the printout provides the appropriate upper-limit values.

Please note tha t the stated upper-limit values a r e conservative since the concrete walls of the sample chamber provide an adequate neutron cavity tha t allows a given neutron multiple chances of detection before being absorbed by materials i n the walls; t h i s e f fec t has not been taken in to account i n this

study, but would, in practice, lower the amount o f plutonium that could be present and still escape detection.

Field Calibration Source Check

The passive neutron counting tube was checked before use by counting the background (ambient) level inside the facility. The counts were compared to previous background counts taken both inside the same room and taken when the tube was calibrated against a known source o f neutrons.

No accuracy or precision noncompliance issues exist for this report

,

Recommendations and Conclusions

The data show that the observed neutron count inside' the sample chamber of the Fuel Element Examination Facility is consistent with background levels. The data supports the claim that less than 0.5 g TRU can be present inside the sample chamber and still avoid detection. As mentioned previously, the 0.5 g value i s conservative, since the concrete of the sample chamber would allow an emitted neutron multiple chances for detection so that detection would actually occur with a smaller amount of TRU.

Hard copies of the data are enclosed for you to maintain as record copies. The hard copies are a documented summary o f data contained in the paginated PNNL Assay Systems Log Book. Any questions may be directed to me at Mail Stop P8-08, by cc:Mail, by FAX at 376-2329, or by phone at 376-0405.

Appendix C-2


Smearable Contamination Estimate.

The smerable contamination is estimated for use in release calculations. The releasable quantity of material is obtain from surface area estimates in the FEF. Vertical and horizontal surfaces are considered separately. Smear survey results are averaged for horizontal and vertical surfaces samples. The results should only be considered as an estimate because the cell surface areas are approximated and quantified smerable contamination from all surfaces were not available.

Surface area calculations are shown inC-1 Detailed drawing of several of the cell components were unavailable. Internal surface area is considered for duct assemblies and components. Smerable contamination estimates from horizontal and vertical surfaces are show inC-3. Contamination levels on all surfaces were not available, however the samples taken are expected to represent the conditions inside the FEF.,

1. Samples are grouped into horizontal, vertical and misc. categories. 2. Calculated surface average is calculated on the number of sample represented by the surface (7 for horizontal, 2 for vertical) 3. Below detection limits are include as 0.0 in the average, because the average will be applied to the bulk area for isotope estimation purposes
