UNDERWATER FILTER/VACUUM UNITS (Model UFV- 600)

Assembly and Operating Instructions 1.0 Introduction

The Underwater Filter System (Model No. UFV-600) is a portable underwater filter system that: • Will aid in the retrieval of foreign material from the water. • Provides supplemental filtration to improve water clarity. • Can be used in the reactor vessel, reactor cavity, and spent fuel pool storage areas in

any nuclear power plant.

The UFV-600 is designed to operate at flow rates between 200- 600 GPM and has the ability to filter sub-micron to 20 micron size particles using disposable filter cartridges. The UFV-600 also has the ability to filter/strain larger size material with stainless steel strainer baskets in place of filter cartridges. The UVF-600 has an electrical disconnect that can be wired into an in plant power panel / outlet and a quick disconnect for all electrical cables including the electrical connection on the submersible pump. The UFV-600 includes a connection point on the filter housing for attachment of rigging to remove the unit from the pools. Rigging is NOT included with the UFV-600. The UFV-600 system operates under negative pressure. This design feature eliminates the need for special bolted pressure closures on the filter and pump housings requiring tooling for operation. Each filter and pump housing seals with a simple flat cover plate held in place by negative pressure during operation. One of the many benefits of this design is that it requires no special tooling to install or remove a pump underwater. With the pump installed correctly in the pump tube, the weight of the pump keeps it in place during normal operation.

2.0 Description of Equipment 2.1 PUMP & FILTER HOUSING (P/N: UFV-600H) -See TNC-004-02 for details-

The housing for the UFV-600 contains four filter tubes and one pump tube. A centered swing lift bale over the pump housing is provided for lifting the UFV-600. The housing is constructed of 304 stainless steel with two Buna-N O-rings in the filter tubes. Depending on the mode of operation, water is drawn into the filters through the top of the open filter tubes or through the 2-1/2” suction hoses. The “dirty” water is drawn down through the (4) filters. Filtered water passing through the filter cartridges pass through a common bottom tunnel connected to the pump housing. The submersible pump draws water from the pump housing and discharges filtered water back to the cavity pool via two 3”diameter discharge hoses. Filters placed into the filter housings are sealed by an O-ring mounted in the filter tube sheet. Negative pressure developed in the filter cartridges provide a positive seal between the filter cartridge and the mounted o-ring. The pump housing has two 1/2”drain holes drilled through the bottom support plate to allow for filling or draining water from the equipment tube housings.

OI-4, Rev 4.0 12/17/12 7

2.2 SUBMERSIBLE PUMP ASSEMBLY (P/N: PP-600SC) -See TNC-009-02 for details-

The PP-600SC is a single stage, 15HP/460V/3Ph/60Hz (dual rated for 380V/3Ph/50Hz) pump and motor comes assembled and ready for operation. The assembly includes the pump cover, discharge piping, the flow sensor tap, and top lifting bail. The pump 4in discharge piping has a flow sensor tap for mounting the flow sensor. Two 3” male camlock horizontal branch connections with hose couplers discharge filtered water back to the cavity pool. The pump has a 1in hole drilled through its internal check valve to allow for pump drainage when lifting and removing the pump from the pool. There is a stainless steel electrical disconnect mounted on the pump cover for the 100 ft PSC-100P power cable. This allows for the removal of the power cable for ease of handling and equipment storage. The electrical disconnect on the pump cover is a “Sea Con” type underwater connector. There is a seal plug (P/N: SC-P) that should be installed on the pump Sea Con connector whenever the power cord is not installed. The seal plug provides sealing of the connector for underwater storage of the pump (without the power cable) and protects the threads of the Sea Con connector when the power cord is not installed.

2.3.3 CB-PR-600-4X (Phase Reversing Control Box) USED from August 2009 to November 2012 See Drawing TNC-018-02

In August of 2009 Tri Nuclear introduced an upgraded version of our standard control box that allows the operator to change the phase rotation of the pump WITHOUT having to open the control box and swap two of the three motor leads.

This is accomplished by a switch on the front of the control box and two motor starters inside the control box. These two motor starters are wired such that when the “Phase Rotation Switch” is in the “A” position the pump motor rotates one direction, and when the “Phase Rotation Switch” is in the “B” position the pump motor rotates in the opposite direction. If the “Phase Rotation Switch” is in the center position, neither motor starter will be energized and the pump will not start.

The CB-PR-600-4X is a NEMA 4X type enclosure (14x16) and has two 460V/3Ph/60Hz solid state controllers with an single adjustable over current trip. The control box has a “Phase Rotation Switch” with safety cover, start/stop pushbuttons and a green “run” indicating light on the front of the panel.

The CB-PR-600-4XP is a NEMA 4X type fiberglass (14x16) that has two 460V/3Ph/60Hz solid state controllers with an single adjustable over current trip. The control box has a “Phase Rotation Switch” with safety cover, start/stop pushbuttons and a green “run” indicating light on the front of the panel. The Phase Reversing feature in this control box allows the operator to change the phase rotation of the pump WITHOUT having to open the control box and swap two of the three motor leads. This is accomplished by a switch on the front of the control box and two motor starters inside the control box. These two motor starters are wired such that when the “Phase Rotation Switch” is in the “A” position the pump motor rotates one direction, and when the “Phase Rotation Switch” is in the “B” position the pump motor rotates in the opposite direction. If the “Phase Rotation Switch” is in the center position, neither motor starter will be energized and the pump will not start. The 460V / 3ph / AC 30amp Nema 4X Twist Lock plugs allow the operator to quickly and easily install the PC-50 drop cable and PSC-100P pump power cable to the control box without drilling and connecting bare cables to internal terminal blocks in the control box.

2.6 FLOW METER AND SENSOR (P/N: FM-600): The UF-600 flow meter is installed to provide a gross indication of system flow. System flow rate is a gauge for determining change in pressure drop through the filters. Under normal operations a filter would be changed out when system flow rate drops to ~50% of clean filter value. The flow meter used for the UF-600 is a self-powered analog meter that provides flow indication from 0-1000 GPM. The flow meter uses the amplitude of the flow sensor signal to drive the 100-microamp meter movement. The flow sensor for the UF-600 is a paddlewheel type flow sensor. The paddlewheel has a re-enforced sleeve that covers the titanium shaft and is designed to minimize wear of the rotor. When water flows past the paddlewheel and it rotates, the flow sensor produces a sinusoidal waveform with frequency and amplitude directly proportional to the flow rate. The sensor comes equipped with 100ft of instrument cable. Flow Sensor Specifications: Output frequency: 5-6 Hz/fps nominal Flow Range: 1-50 fps Linearity: + 1% full range Flow Meter Specifications: Input signal amplitude: 0.4 V peak to peak minimum Input Frequency range: 0-200 Hz Meter Range: 100 micro amps + 2% at full deflection

2.8.3 BUOYANCY CHAMBER (P/N: BC-1)

Tri Nuclear has developed a Buoyancy Chamber that slides over the pool pole. It is a 6in x 18in long stainless steel chamber that provides positive buoyancy for the pool poles. The effect of this positive buoyancy is to reduce the overall weight of the assembled pool poles for the operator. Each Buoyancy Chamber reduces the weight of the pool by approximately half. The BC-1 Buoyancy Chamber has a handle for ease of moving and installing on the pool pole.

2.9 TRI NUCLEAR FILTER CARTRIDGES Tri Nuclear Filter Cartridges are designed for inside to outside flow. This keeps major contamination on the inside of the filter cartridge and reduces contamination exposure to workers during filter change out and transfer. The Polyester filter media has a higher dirt loading capacity than other similar media and results in longer filter runs. It also has a higher resistance to gamma radiation.

CAUTION: At 106 RADS accumulated dose, filter cartridges can start to break down.

4.1.7 Discharge Hoses

Couple the two 25 ft. long 3" discharge hoses to the top discharge connectors on top of the pump cover discharge pipe. Connect the two diffuser pipes to the opposite ends of the discharge hoses and tie handling lines to the ends for moving the hoses underwater to desired locations. The diffuser pipes are used to dampen a hose “whip” reaction which would occur on the end of a discharge hose.

NOTE: THE UFV-600 MUST BE RUN WITH EITHER SUCTION OR DISCHARGE HOSES

INSTALLED. IT IS NOT DESIRED OR REQUIRED TO RUN THE UNIT WITH BOTH SUCTION AND DISCHARGE HOSES INSTALLED.

4.1.8 Suction Hoses

Couple the two 50 ft. long 2-1/2” suction hoses to the suction ports on the housings. Ensure that the suction hose standoff UT-11B is installed on the end of the hose. This will prevent the hose from “deadheading” on the pool floor or wall. See section 5.1

4.2 Assembly of Unit 4.2.1 Lower the UFV-600 Housing into the cavity / SFP

Attach rigging lines (supplied by purchaser) to the main unit, and carefully lower the assembly to the bottom of the pool and tie-off the lifting line to the side of the pool.

CAUTION

SLOWLY LOWER THE UFV-600 HOUSING INTO THE WATER. THIS ALLOWS WATER TO FILL THE HOUSING FROM THE TWO 1/2IN DRAIN HOLES IN THE BASE PLATE. LOWERING THE UNIT TOO FAST MAY CAUSE IT TO BECOME UNSTABLE UNTIL IT FILLS WITH WATER

(The UFV-600 system may be prepositioned in the cavity prior to flood up)

After the UFV-600 housing is in place, the pump may be lowered into the pump tube.

4.3 Install Filter Cartridges Install four (4) new filter cartridges into the UFV-600 housing.

Proper Filter Selection is “a must” in order to achieve desired results. See Tri Nuclear Drawing TNC-019-02 for information on Tri Nuclear Filter Cartridges. Filter Cartridges may be installed AFTER the housing has been lowered into the pool. Guidelines for filter selection are show below: • The 10 micron filter VCPH-10PE is normally chosen for high dirt loading when

vacuuming settled particulate. • The 5 micron filter VCPH-5PE will capture material that might bypass the 10 micron

during vacuuming. • The 1 micron filter VCPH-1PE is excellent for water clarity issues. • The 0.3 micron VCPH-0.3PE filter is used for “polishing” when water clarity is “a

must”.

4.6 Phase Rotation Check with CB-PR-600-4XP Phase Reversing Control Box

IMPORTANT - READ THIS STEP CAREFULLY!

!!!WARNING!!!

Do not run the pump until a proper phase rotation check is made! Running the pump in reverse for any long duration WILL damage the pump!

!!!WARNING!!!

DO NOT RUN/BUMP THE PUMP DRY OR OUT OF THE WATER!

SEVERE DAMAGE TO THE PUMP MAY OCCUR!

To check for proper phase rotation of the pump motor, turn on the unit and record the flow rate. Switch the phase of the pump using the phase rotation switch, start the pump and again record the flow rate. The proper phasing will give the higher flow rate. To change the phase of the pump, stop the pump (if running), open the safety cover, Turn the switch to the Phase A or B position, Close the safety cover, and restart the pump.

!!!WARNING!!!

DO NOT START THE PUMP MORE THAN ONCE EVERY TWO MINUTES This phase rotation check must be performed each time the motor or starter box is disconnected from the electrical power source.

OI-4, Rev 4.0 12/17/12 46

5.0 OPERATIONS 5.1 The UFV-600 can be operated in two different configurations. This system combines both

the vacuuming ability of the UFV-260 and the high flow of the standard UF-600.

NOTE: THE UFV-600 MUST BE RUN WITH EITHER SUCTION OR DISCHARGE HOSES

INSTALLED. IT IS NOT DESIRED OR REQUIRED TO RUN THE UNIT WITH BOTH SUCTION AND DISCHARGE HOSES INSTALLED.

5.2 Vacuuming Operations. See drawing TNC-004-02

Vacuum operations are accomplished by attaching the two 2-1/2” suction hoses to the suction connections on the unit. Attachment of the suction hose stand-off (UT-11B), vacuum nozzle (UT-7-2.5) or vacuum head (UT-5SP-2.5) to the end of the vacuum hoses is necessary to prevent the hoses from becoming “deadheaded” against the pool floor or wall.

During vacuuming operations, all four filter covers must be shut to prevent flow imbalances between the filters.

Each suction hose is tied to a single bank of 2 filters. Vacuuming with one suction hose only

can cause an imbalance in filter loading between the two banks of filters. 5.2.1 Vacuuming with the Vacuum Cleaner Head (UT-5SP-2.5)

For vacuum cleaning the bottom of a pool, use the four wheel vacuum cleaner head (UT-5SP-2.5) attached to the bottom end of the pool poles. The suction end of the PH-2.5x50 hose is attached to the hose coupler on the vacuum cleaner head. Dose rates on the filter should be closely monitored since high dose rates may be reached before the filter shows much loss of flow. The UT-15 Utility Chain may be attached to the loop on the Vacuum Cleaner Head to assist in moving it around the bottom of the pool.

5.2.2 Vacuuming with the Vacuum Nozzle (UT-7-2.5)

Vacuum cleaning around fuel rack ledges or the rim of an open reactor vessel may be accomplished using the vacuum cleaner nozzle (UT-7-2.5) attached to the end of a suction hose and to the bottom end of the pool poles (SP-1) using the hose-to-pole clamp (UT-6SP). This fixture will permit the vacuum nozzle to be used in either a vertical, 45deg., or horizontal position.

OI-4, Rev 4.0 12/17/12 47

5.2.3 Pool Poles (SP-1, SP-1x5, SP-1x3 & SP-1x2) The pool poles come in 4 different lengths – 10ft, 5ft, 3ft & 2ft long. Determine the depth

the vacuuming will take place and assemble the appropriate number of pool poles for optimal operation interaction with the pool poles and tee handle.

5.2.3.1 Buoyancy Chambers (BC-1) The Buoyancy Chamber (BC-1) is designed to reduce the weight of the pool pole by about

half. After determining the number of pool poles to be used, install the same number of Buoyancy Chambers on the uppermost, fully submerged pool pole. The placement of the Buoyancy Chambers at the top end of the of the Pool Pole sections helps the operator manipulate the tooling, especially the UT-5SP-2.5 Vacuum Cleaner Head.

5.3 Water Clarity Operations See drawing TNC-004-02

Tie-off the two discharge diffuser ends of the discharge hoses in a location to provide good cross circulation of the water in the pool. The filter covers maybe open or shut during water clarity operations.

CAUTION:

Operating the unit with no discharge hoses attached minimizes pool cross circulation and will lead to inefficient water filtration that may cause water turbidity problems.

OI-4, Rev 4.0 12/17/12 48

5.4 Filter Change Out

Continue operation of filters until they are considered depleted. This should be determined from experience, either by reaching a predetermined maximum dose rate on the filters, or by a decrease in flow rate to approximately 50% to 60% of the initial clean filter flow rate.

NOTE: See the attached operating procedure (OI-6) for using the rope filter lift tool. NOTE: Filter cartridges can take several minutes to flood while trying to submerge

them in the pool. The flooding time can be minimized by pre-soaking the filters

5.4.1 Turn off the PP-600SC Pump. 5.4.2 To change-out an expended filter cartridge from an Underwater Filter/Vacuum Unit, first

lower the Underwater Filter Storage Rack with new filter cartridges down to the bottom of the pool adjacent to the Underwater Filter/Vacuum Unit. Allow the filters to fill with water before lowering quickly into the pool.

5.4.3 Remove and replace the expended filter cartridges using per OI-6. 5.4.4 Start the PP-600SC Pump. Read and record initial clean filter flow rate for future filter

cartridge change out. 5.5 Pump Change Out When it becomes necessary to remove the pump perform the following: 5.5.1 Turn off the pump. 5.5.2 Using the UT-14 Pump Lift Hook, lift and remove the pump using the overhead crane.

OI-4, Rev 4.0 12/17/12 49

5.5.3 Install the pump per section 4.2.1

5.5.6 If the pump was disconnected from the electrical power source or it was replaced, perform the phase rotation check in section 4.3 prior to operations.

5.6 Troubleshooting

See OI-5, Tri Nuclear Pump Trouble Shooting Guide, for trouble shooting guidelines with the UFV-600.

OI-4, Rev 4.0 12/17/12 50

6.0 Storage Requirements 6.1 Caution should be taken to NOT store any plastic components (eg. filters or hoses) near high

radiation fields associated with equipment such as fuel bundles, LPRM’s or control blades. Breakdown of such components can occur with accumulated exposures of 106R. For this reason, precautions should be taken to minimize accumulative dose for the following components: suction hose, filter cartridges, power and instrument cable, flow sensor, and electric motor. All components are chemically suitable for long term storage in the fuel pool cavity environment.

6.2 The preferred method of storing the submersible pump assembly when not in use is underwater. Periodically, running the pump (at least once a month) is also desirable to prevent seals from remaining in a stagnant condition.

OI-4, Rev 4.0 12/17/12 51

7.0 Precautions and Warnings

WARNING: Do not run/bump the pump dry or out of the water! Severe damage to the pump may occur! WARNING: Install the power cord to pump pigtail HAND TIGHT ONLY. Do NOT use any tools (pliers, channel locks etc.) to tighten the connection. CAUTION: Do not start the pump more than once every 2 minutes or 300 starts/day. Damage to the motor winding insulation may occur.

CAUTION: Do not run the pump until a proper phase rotation check is made! Running the pump in reverse for any long duration will damage the pump! CAUTION: When installing and removing the power cord, do not move the power cable connector with side to side motion in an attempt to install or remove it.

unthreaded fully and pull in the vertical direction ONLY to remove the power cable from the pump.

CAUTION: Slowly lower the UF-600 housing into the water. This allows water to fill the housing from the two 1/2in drain holes in the base plate. Lowering the unit too fast may cause it to become unstable until it fills with water.

CAUTION: The flow meter dial read-out gauge is a delicate instrument (milliammeter) and should be

protected from rough handling. It could be broken if dropped on the floor. Mount it to the UT-10A control panel and hung on a suitable railing for protection. NOTE: Perform the flow meter check before installing the Underwater Filter units into the pool for the first time, whenever the flow meter or sensor is replaced, or anytime the flow sensor is suspected of being damaged.
