Continuous Air Monitors Seven continuous air monitors are provided. The units are supplied by Nuclear Measurements Corporation, Indianapolis, Indiana and are described belows 1-Model PAPM-1 Prograamed Alpha Plutonium Monitor including two ASC-1 alpha scintillation detectors utilizing ZnS phosphor and one LCRM-55 dual logarithmic count-ratemeter with two 5~
cycle meters range 10 to 1,000,000 cpm and power supply.
C Each ratemeter has a dual contact meter manually set at a chosen scale for alert or fail-safe and alal'ffl condition. One continuous duty positive displacement industrial air pump driveh by a belt coupled, sealed ball bearing motor with an automatic switching valve which shifts collection from one collector to the other. The time cycle is controlled by a programmer with 1 through 24 ho~r cycles available. The count-ratetneter output is recorded oh a* two per\ contlnuous
. strip chart recorder. During the last hour of off-collection time, the activity remaining on the filter is counted and the total count is printed out on paper tape. Assuming a 10 cfm sa~~ing rate and a concentration of plutonium in air of 10* ~c/cc, the build-up activity on the filter paper would be 37.8 cpm per hour of which 3~ or 13.8 cpm would be detected. At the end of 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> the detector would see 165 cpm above background, not enough to cause an alal'ffl. The

Then, from the 23rd to the 24th hour following the lnitial collection, the total count on the first collector would be recorded. The natural activity background should be about 300 to 500 counts per hour and the plutonium count would be about 9,900 for the one hour count. The unit then would alal'ffl after 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> in a C

All three units have glow tube decade readou t. Each channel has discri minat or contro ls provid ing separa te channels of pulse heigh t analy sis. Prese t time contro l is in 20 steps from 3 seconds to 100 minutes. Pre!et cougts may be select ed on either scaler in increments from 10 to 10.

The automatic changer and detect ors ~re mounted in an eleven cubic foot freeze r for contro lled temperature counti ng. The automatic contro l unit C programs operat ion of the sample changer. Contro ls may be set to count anywhere from 1 to 100 samples and the unit will recycl e continuously if repeat data are requir ed on a batch of samples. The unit may also be set for repeat counting of a single sample. If power failur e should occur while a. count is in progre ss, the contro l unit will clear and ~peat the count autom aticall y when voltag e is restor ed. A manual over-r ide button allows the operat or to select any aample for a specia l count1 1-Model A Digita l Printe r provides a printe d record of counting data on a strip of paper tape._ For each sample, the printe r record s sample number, elapsed time and counts on both scaler s.
In the operat ion of the liquid scinti llatio n counting system, radioa ctive decay events occurr ing in the sample cause scinti llatio ns which are at seen simultaneously by both photo multip lier tubes, giving rise to pulses the phototube outpu t. Pulses front the photomultiplier& pass through
-preamplifier& and into three separate ampli fiers . Pulses from the for "Analyzer" phototube then go to the discri minat or pairs A-Band C-D pulse- heigh t analy sis. The "Monitor" phototube functi ons o~ly to or determine whether a pulse is the legitim ate result of a decay event whether it arises from photo multip lier tube noise. Pulses fallin g between A and Bare fed to the red scaler and pulses fallin g between C and Darepass fed to the green scaler . outpu t pulses from all of the discri minataneou ors through the coincidence circui try and only pulses occurr ing simultof sly in ~oth photomultiplier& are counted. This result s in some loss
Appendix 9.37 efficiency but effectively eliminates phototube noise. The two channols may be uied to estimate the amount of quenching in a sample so that '
appropriat~ *correction factor*s may be applied to the count. The disinte-gration rate of* an unknown sample may be detel'mined by counting the I

Appendix 9.51
- Stack Monitoring System The stack monitoring system consists of two channels of monitoring; the first channel for beta-gamma emitting particulates, and the second channel for iodine-131 with readout and alarm locally and at the Control -Room Panel. The system is supplied by Tracerlab, a division of Laboratory for Electronics, Inc., Richmond, California. The following equipment is included:
1-Isokinetic nozzle; 1-Model MX-14C Pumping System with a 10 cfm sliding dry vane pump driven by an electric motor through double V-belts, a control valve, a calibrated fixed orifice, flow gauge, and necessary piping; 1-Model MA-lB Filter Tape Transport Mechanism, an advanced version of the Brookhaven design. A solid capstan with milled slots rides on a Teflon shear valve which limits the air bypass around the filter paper to less than 2 percent. The filter paper is held against the rotating capstan by the pressure differential across the paper and is moved by the rotating capstan. Two filter tape speeds are provi-ded; one inch per hour for normal operation,and 28 inches per minute for fast advance to clear contaminated tape from the detector areas; 1-Model MD-lB Beta-Gamma GM Detector, a halogen-quenched end window detecto~, 2t inches in diameter. The window is mica -- less than 4 mg/cm2 thickneps* The detector is shielded by two inches of lead;
!-Model RM-20B Precision Log Ratemeter with a ~inch panel meter indicating the counting rate directly in counts per minute on .a switch selected three decade (10 ~o 104 cpm) or five decade (10 to 10 cpm) scale. One additional scale indicates high voltage. Th~
ratemeter has an adjustable alarm point and a manual reset to pro-vide "memory". The meter relay automatically resets to permit meter to read cpm below the alarm point~
1-Model RM-40B Dual Power Supply with main power switch, high voltage switch, two high voltage adjustment screws and alarm reset. Unit supplies high voltage for the system detectors; 1-Model MI-5B Iodine Sampler and Shield Assembly, with a holder for a two-inch diameter activated charcoai filter and a three-inch thick lead shield for the detector;
!-Model MD-5B Gamnd Scintillation Detectors with a Ii-inch diameter x 1-inch sodium iodide, thallium-activated crystal, a Dumont 6292 photomultiplier and a 100-gain preamplifier.

It Is calcul ated that It would take about 40,000 years for the high level wastes and 5,500 years for the low level wastes to move through this silty till from the point of sto_rage to the neares t ravine .
1.28 The good Ion exchange capac ity of the soil, the slow movement from the waste storag e facili ties to the ravine s, the existe nce of the ravine s, and the fact that all ground water flows a creek within the site render the site adapta ble to an excell ent to monito ring system and allow excell ent contro l over radioa ctive wastes stored on the site.
Seismology 1.29 Western New York ts an area of low selsm lctty and the danger of earthq uakes which might ruptur e any of the plant~ s facili ties Is minimal. The neares t feult to the site Is at a distan ce of 35 to 40 miles, and this Is more proper ly classi fied as a minor earth struct ure rather than a fault. Thus, the site presen ts no seismo logica l problems.
Sumnary 1.210 In sunrnary, the chara cteris tics of the site are such that
( the health and safety of the public should not be endangered by operat ion at the site of the NFS chemical proces sing plant or by the storag e of low or high level wastes . The remoteness of the site from popula tion cente rs, the low popula tion densit y for 25 miles beyond the site, the large exclus ion area, and the meteo*r ology, all are favora ble factor s to assure protec tion both from normal operat ion of the facili ty and 11 from any credib le accide nts.

- Chemical Processi ng I I
- 1. 44 1-n the chemical processi ng cel 1, the chopped foel canniste rs are placed Into one of the dissolve r barrels . Nitric acid and water are metered Into the dissolve r from the solution makeup area so that the ~
final solution contains no more than 7. 5 grams per liter of U-235, a critical ly safe concentr ation In all geometries and quantiti es . Complete dissolut ion Is expected to take about 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> . The off-gas treatmen t I I Includes a down-draft condenser on the dissolve r, a secondary condense r, .I a scrubber , Iodine removal on a silver reactor, and filtratio n through a parallel filters . The off-gas Is then added to the general ventilat ion system for further filtratio n before discharg e to the stack. I 1.45 Vhen the dissolut ion of the fuel Is canplete , the solution Is cooled and Jetted to a 304-L stainles s steel account ability and feed '
adjustme nt tank. The dissolve r ts then heated to dry off the hulls, 11 which are returned to the process mechanical cell. The hulls are Inspecte d and packaged and sent to the solid waste storage area. The account ability and feed adjustme nt tank Is equipped with heating coils, I
a condens er, air sparger, liquid level and specific gravity measurement, circulat ing sampler, and temperat ure measurement. After analysis and adjustme nt* of the a>ncentr atlon and acidity of the feed, It Is Jetted to the partitio n cycle feed tank from wht.ch It Is fed to the extracti on columns .
-, Solvent Extracti on 1.1'6 Solvent extracti on Is done by a Purex-ty pe process, which Is performed In the contact process area. The base-lin e fuel Is put ,!
through a partitio n cycle, In which a TSP-kerosene solvent Is used to extract the. uranium and plutonium from the feed stream, leaving the bulk of the fission products (:)99.9%) In an aqueous stream which becomes II the major fission product waste stream of the plant. "The plutonium and uranium are also separate d In this first extracti on cycle Into two l separate , partlell y d~conta~ lnated, aqueous product streams . These l two product streams a re then separate ly put through addition al solvent extract ion cycles to complete the removal of remalnln~ fission products .
1.47 The uran l un and plutonlu n product streams are first collecte d In the feed conditio ner tanks for sampling, analysis , and adjustme nt of II I
acid concentr ation. The streams are then put through addition al solvent extracti on cycles In which the product Is extracte d Into an organic phase II In one column and ther. returned to an aqueous product stream tn a second colunn. The uranium stream goes through two such cycles and the I pluton i um through *one . I I

Product Purific ation and Concentration (
1.48 The uranium product stream from solven t extract ion Is collect ed I~ a product evapor ator feed tank from which It Is Jetted Into one of l'WO evapor ator tanks for concen tration . The condensate Is collect ed In one tank and the concen trate In another . The concen trate Is subject ed to a silica gel treatment for final decontamination. The product Is then placed In one of two sampling tanks, and after sampling and analysi s It Is transfe rred to one of a series of storage tanks .
Highly enriche d uranium Is drawn from th*** tanks In small quanti ties and mixed with water to a concen tration critica lly safe for shipment In tank trucks; the low. enriched uranium Is already at an acceptable concen tration from a crltl~a llty standp oint.
1.49 The plutonium product stream Is collect *~ In an Ion exchange condit ioner tank from which It Is p1111ped Into one of three anion exchange columns for concentration and. final decontamination. It Is eluted from the columns and evaporated In a titanium vessel. The condensate Is pwnped back to th* feed adjustment tank and the concen trate Is collect ed In one of three plutonium storage tanks, from which It Is packaged for shipment . _All of the packaging and shipping equipment Is enclosed In separa tely ventila ted glove boxes. The shipping bottles are placed In secondary contain ers and stored In the product storage area In bird cages awaitin g shipment.
Solvent Recovery C
- 1. 410 The plant Is designed to reuse the TIP-kerosene solven t, wh ich must be cleaned of fission products prior to reuse. To accomplish this, the solven t Is first washed with sodium bicarbonate and then with dilute nitric acid.
Ac id Recovery .
- 1. 411 Alt of the aqueous waste streams wilt contain nitric acid which wltl be recovered to reduce the solid loading on the waste tanks .
Acid recovery Is accomplished through the use of two waste evaporators following which the acid Is subject ed to an acid fractio nation step to concen trate It Into a reuseable conditi on.
Rework System 1.412 All waste streams will be sampled and analyzed prior to being discard ed to the waste disposa l system. In the event that the product In the waste stream Is above specifi cation, facilit ies are provided to rework the wastes . They are recycled through a feed tank and a rework evapor ator . The bottoms from this evapor ator are pumped back to the feed adjustment tank to be subject ed to further solven t extrac t Ion .
