AN IMPROVED, COMPUTER-BASED, ON-LINE GAMMA MONITORFOR PLUTONIUM ANION EXCHANGE PROCESS CONTROL

by

Noah G. Pope and S. Fredric Marsh

ABSTRACT

An improved, low-cost, computer-based system has replaced a previ-ously developed on-line gamma monitor. Both instruments continuouslyprofile uranium, plutonium, and americium in the nitrate anion exchangeprocess used to recover and purify plutonium at the Los Alamos Pluto-nium Facility. The latest system incorporates a personal computer thatprovides full-feature multichannel analyzer (MCA) capabilities by meansof a singh+slot, plug-in integrated circuit board. In addition to control-ling all MCA functions, the computer program continuously corrects forgain shift and performs all other data processing functions. This Plu-tonium Recovery Operations Gamm a Ray Energy Spectrometer System(PROGRESS) provides on-line process operational data essential for ef-ficient operation. By identifying abnormal conditions in real time, it al-lows operators to take corrective actions promptly. The decision-makingcapability of the computer will be of increasing value as we implementautomated process-control functions in the future.

INTRODUCTION

The major aqueous process used to recover and pu-ri& plutonium at the Los Alamos Plutonium Facilityis anion exchange in nitric acid. This process is nearlyideal for separating plutonium from a wide variety ofimpure materials, as the anionic nitrate complex ofPu(IV) is more strongly sorbed thau any other com-plex ion, and few other elements show even moderatesorption from nitric acid.l

Operators at Los Alamos have traditionally fol-lowed a fixed procedure, even though feed solutionsvary over a broad range of impurity compositionsand concentrations. Before the earlier on-line gammamonitor2 became available less than two years ago,

processoperatora based most process-controldecisionson only their visual observationaand intuition.

Although the earlier version of the on-line gammamonitor significantly improved the efficiencyof thisanion exchange process, it lacked the reserve compu-tational power and flexibilityneeded to support a par-allel Los Alamos development effort directed towardthe automation of major aqueous processes.

The objective of this work was to develop a com-pact, low-cost, computer-based version of the on-linegam.ma monitor. This improved version would pro-vide sufficientreserve capability to compile real-timeprocess-controldata from a variety of monitors duringfuture automated process-controlapplications.

Although 239Puand 241Amhave ga.mma rays thatare directly suitable for passivegaroma assay, the nat-ural and depleted uranium impurities in typical LosAlamos feed materials do not. A novel and indirect

radiotracer technique therefore is used. The positionof any uranium impurity that passes through the an-ion exchangeprocess is traced by 237U,a minor alpha-decay daughter of 241Puthat is alwayspresent in plu-tonium processed at Los Alamos. This radiotracer

technique is detailed in a separate report.2A high-purity germanium garoma detector moni-

tors the outlet stream from the anion exchange col-umn (Fig. 1) as it flows through an existing three-quarter-inch stainless steel process pipe. The detec-tor is shielded from background radiation by a leadshield (minimum 1.5-inch thickness) that contains alining of 0.030-inch cadmium to absorb fluorescentx rays iiom lead. Another cadmium absorber is in-serted between the pipe and the detector to attenuatea major portion of the abundant 59.5-keVgamma raysfrom 241Am(Fig. 2).

The complete on-line garoma monitor system(Fig. 3) provides real-time elution profles of ameri-cium, uranium, and plutonium (Fig. 4) as these ele-ments elute from the anion exchange column. Thechanging detector signals reflect the varying com-position of the outlet stream from the anion ex-change column as (1) americium impurity elutes first,(2) uranium and other impurities elute next, andfinally (3) purified plutonium elutes after being re-duced from strongly sorbed Pu(IV) to nonsorbedPu(III). These recorded elution profiles provide datafrom which operators can optimize many process pa-rameters. The stripchart also provides a permanentrecord of the daily performance for each anion ex-change system.

COMPUTER PROGRAM SYNOPSIS

The Plutonium Recovery Operationa Gamma RayEnergy Spectrometer System (PROGRESS) programthat we developed consists of nearly 1000 lines ofBASIC code that controlsall data acquisition,process-ing, and output operationa. Softwarefor the PCA mul-tichannel analyzer plug-in card (Fig. 5), supplied byThe Nucleus,Inc., must be loaded manually before theBASIC program can be executed. The PROGRESSprogram (seeFig. 6) then controls the vendor-suppliedsoftware. (Appendix A is a detailed description of thisprogram.)

Many parameters and functions of the PCA-2OOOplug-in card can be directly accessedfrom a high-levelinterface language. BASIC was selected for this appli-cation because it is easily programmed and is capableof interfacing with assembly-languagesubroutines by

means of POKE statements and PEEK and USR func-tions. These commands allow subroutines, flags, andpointers in the PCA software to be read directly intoor out of memory locations on the PCA board. Thedetailed information required to directly access PCAsoftwareand firmwarewas obtained from The Nucleus,Inc.3’4

Microsoft Corporation’s GW-BASIC was selectedfor compatibility with the DataCAT computer. (TheDataCAT computer was selected because its construc-tion and small size make it much better suited for achemicalplant environment than are competitivecom-puters designed for officeuse.)

Vendor-suppliedsubroutines directly (1) change thecursor position, (2) update and display the spectrum,(3) calculate the region-of-interest(ROI) centroidaandnet integrals, (4) preset data acquisition times, and(5) start andstop data acquisition. Direct alteration ofmemory locations that contain logicalon-and-offbyteconfigurations accomplishescertain other operations,such as setting and clearing ROIS.

Many functions require that parameters or data beconverted from regular decimal notation to multiple-byte binary or packed binary coded decimal (BCD)format. Large portiona of several subroutines therefore consist of algorithms that accomplish theseconversions.

PROGRAM STRATEGY

High-purity germanium garoma detectors routinelyproduce high-resolution gamma peaka. Gamma spec-tral measurements of high-resolution peaks are mostreliable when the ROI is only slightly wider than thepeak being measured. Such tightly definedROIS,how-ever, leave the measurement system susceptible tolarge errora if peak positions shift during the meas-urement period. An external electronic module typi-cally is used to prevent gain-shifterrors. Such modulesautomatically sense gain shift in the analog-to-digitalconverter (ADC) and adjust as required to correct forthe detected shift. Unfortunately, the internal ADCcircuitry on a PCA-2OOOplug-in board ia inaccessibleto such external electronic gain stabilizers.

Instead, PROGRESS uses two gamma rays (oneat 81 keV and the other at 356 keV) from a 133Bacalibration source as gamma-energy reference points

for a unique software-controlled gain stabilization.PROGRESS first locates these two peaks, whichnearly bracket the gamma-energy range of intereat,and then determines the centroid for each. Baaed onthe channel positions of these two calibration peaks,ROI positiona are calculated and reset for 241Am(59.5keV), 239pu (lzgkeV), ~d zsl’u (208keV). ‘l%isrecalibration sequence is automatically repeated approximately every 35 seconds.

PROGRESS then initiates a spectrum acquisitionloop (preset for 30 seconds in our application). Updated, cumulative spectral data are displayed on thevideo screen approximately every second during theacquisition period. At the end of the acquisition pe-riod, the program interrogatea each preset ROI andcalculates the net integral for each peak. These valuesare converted to a predetermined logarithmicscaleandare output to the plotter during the subsequent dataacquisition cycle.

The PROGRESS program may be executed in ei-ther an interpretive or compiled mode. The veraioncompiled by an IBM BASIC Compiler requires approximately 35 seconds to execute a complete cycle(of which 30 seconds is data acquisition time). Thisis approximately 5 seconds less than the 40 secondsrequired to execute the interpretive veraion. An-other compiler, IBM QuickBASIC, was rejected be-cause it was incompatiblewith severalessentialBASICcommands.

The complete PROGRESS program (see AppendixB) includes numerous comment statements in thecode. Although these statements consume a smallamount of computer time in the interpretive mode,they consumeno time in the compiledmode and theyserve as a diagnostic aid to users who are unfamiliarwith the software.

MAJOR PROGRAM SECTIONSEnergy Calibration

User-Defined Parameters

Detailed beloware certain essentialparameters thatinitially must be definedby the user. These parameterdefinitionsare retained as default settings unless theyare intentionally changed.

Barium-133 Calibration Source. Gammapeaksat 81 keV and 356keV from the 133Baradioiso-tope calibrationsourceare usedto recalibratethe sys-tem after each cycle. The program prompts the op-erator to define the channel numbers that bracketeach of these two ROIS. These ROI settings are en-teredmanuallyin the PCA-2000mode beforeprogramexecution.

Data Acquisition Time. The data acquisitiontime must be specifiedby the operator; a time of 30seconds@ically is used.

Plotter Scale. The y-axis of the plotter repre-sentsthe log of thenet peakarea,whichtypicallyis di-vided into four decades that cover the range of 1 to10,000.The scaleassignedto the x-axis (time) is spec-ified by the operator to allow the output to be ex-pandedor contractedaccordingto the estimatedtimerequiredfor a givenprocess run. This time-scalecon-trol ia achievedby varying the center-t~center spac-ing between adjacent plotted characters in incre-ments of 0.001 inch. Default valuea are deilnedseparately.

System Initialization

After the operator initializea the system using pa-rameters selected above, the PROGRESS programcontrols the followingoperationa: (1) The blank plobter paper is scaled and advanced to the proper start-ing position. (2) The MCA display screen is ac-tivated to update and display the spectral dataand system parameters. (3) The data acquisition

ROIS for the two gamma peaks of the 133Baradioisotope calibration source, as defined in thePARAMETER INPUT section, are set and their cen-troid locations are calculated. The centroida are aa-signed gamma energy values of 80.998 keV and356.005keV, respectively. The linear relationship be-tween gamma energy and MCA location is calcu-lated as C = mE + b, where C is channel num-ber and E is energy. The slope value, m, is equalto the number of channels that separate the centroidsof the 81-keV and 356-keVpeaka divided by the en-ergy that separates them. Substitution of the chan-nel and energy values for either peak into the equa-tion will provide the value of b, the zero inter-cept.

From this equation the peak centroid positiona arecalculated for gamma energies of 59.5 keV, 129 keV,and 208keV, used to monitor 241Am, 239Pu,and 237U,respectively (Fig. 4). The number of channels to theleft and the number ofchannelsto the right of the peakcentroid that definesthe ROI for each peak are preset,based on empiricalpeak resolution values, which are afunction of the peak energy and system resolution.

Spectral Acquisition

Previously collected data are cleared by the ClearSpectral Data function. A new acquisition cyclethen is initiated by setting the START/STOP DataAcquisition function to the “ON” position. Dur-ing the new data acquisitioncycle,processeddata fromthe previous acquisition and calculation cycleare out-put to the plotter. A print bulfer in the Houston In-struments plotter allowsthese data to be quicklytrans-ferred without interference to the ongoing acquisi-tion cycle.

Two alternate function-key combinations may beused during the spectral acquisition loop. TheAlt and F1 keys may be simultaneously pressed to

8

record the position of significant events with a special mark at the top of the plotter paper. simul-taneous depression of the Alt and F1O keys termi-nates the data acquisition loop and redisplays an op-tions menu. From this optiona menu the opera-tor may elect to (1) resume the measurement cy-cle in progress, (2) begin a new measurement cy-cle, or (3) exit the program and return to DOS.

If neither alternate function-key option is invoked,data acquisition continues until the flag for data ac-quisition preset time registera “OFF” or timed-outstatus.

ROI Net Integral Calculations

The net integral of each ROI is sequentially cal-culated by invoking a Net Integral Calculation func-tion within the subroutine for reading net inte-grals. This algorithm is repeated for each of the spec-ified ROIS. The ROI being processed is desig-nated by placing the MCA display cursor within thatROI.

Clear ROIs

The ROIS used to monitor 241Am, 239Pu, andZSTUme Clemedafter each acquisition cycle iS com-plete, in preparation for anew energycalibration. Pro-gmrn control then returns to the Energy Calibra-tion algorithm at the appropriate portion of the pro-gram (Fig. 6).

SUPPORTING SUBROUTINES

Set and Clear ROIS

The vendor-supplied Set and Clear ROI func-tion requires that each channel included in an ROIbe addressed and interrogated on an individual ba-sis. This time-conauming procedure requires approx-imately 0.3 second per channel, or 3 seconds for a10-channelROI. The more efficientsubroutine devel-oped in the PROGRESS program allows the ROI tobe set and cleared by manipulating a portion of mem-ory that contains an ROI “ON/OFF” flag. This sub-routine cau set or clear a 15-channelROI in less than1 second.

PEEK-ing

The BASIC language PEEK function, used inconjunction with the POKE statement, allows val-ues stored in memory locations to be read di-rectly. This subroutine allows the program to inter-rogate important memory flags and pointers, such asthe preset time or data acquisition flag and the ROIstatus flag.

Using Poke Statement to Replace Value inMemory

It can be advantageousto “trick” the PCA-2000byreplacing existing values in memory with new, moreuseful values. For example, the vendor-suppliedfunc-tion that moves the display cursor to another loca-tion must be invokedrepeatedly until the desired chan-nel location is reached. Alternatively, the value inthe memory location that contains the current cur-sor position may be replaced with the value of the de-sired new cursor position. When the PCA-2000checksfor the current cursor location, it finds this newvalue and responds by moving the cursor to the de-sired position in a single operation. This subrou-tine can save 5 to 10 seconds of processing time percycle.

POKBing

Value-smay be placed directly in selected mem-ory locations using the BASIC language POKE state-ment. Several vendor-supplied functions are in-voked by POKEing a function number into the ap-propriate memory location. These functions includeData Acquisition Start/Stop, Spectral Data Clear-ing, Single-ChannelCursor Movements,Centroid Cal-culations, and Net Integml Calculations.

Centroid Calculation

The vendor-supplied Centroid Calculation func-tion requireathat the cursor be positioned withinthe selected ROI. This subroutine directs the pro-gram to another subroutine that moves the cur-sor, as well as invokesthe centroid calculationfunc-tion. The calculated centroid value then is con-verted from packed binary coded decimal into reg-ular decimal notation for use in subsequentcalcula-tions.

9

Net Integral Calculation

The vendor-supplied Integmd Calculation func-tion is invoked and read (PEEK-cd) out of mem-ory by this subroutine. The value then is con-verted from a binary number into decimal nota-tion for subsequent manipulation.
