Each monitoring unit is placed on a ten foot high platform to keep it above the maximum anticipated snow level. Plant Site Air Sampler An air sampler is available for sampling air around the plant site. The unit is supplied by Gelman Instrument Company, Chelsea, Michigan and is described belows 1-Model 26001 Nuclear Air Saq,ler capable of sampling uously at a constant rate of l CFM. The flow is controlled by a limiting orific, installed in the sampling line between the filter bowl and intake of a vacuum pump. The amount of air sampled is recorded on a dry gas meter and a vacuum gauge is included to correct the indicated flow for error due to pressure drop across the filter. A running time meter indicates cumulative operating time in hours and tenths. Samples are collecte~ on two 2-inch in-line type filter holders. The entire assembly is housed in a heavy gauge steel cabinet fitted with louvers for ventilation. ---*----------*-------! I -~ C C Appendix 9.33 Plant Air Particulate Sampling System An in-plant air sampling system is available utilizing a central vacuum pump and vacuum headers to all building occupied areas. There are 54 area air sampling stations and 19 in-cell remote air sampling stations available for use. Each area air sampling station consists of a line to the vacuum header with a valve, a Gelman Model 8224, 10-84 1pm air flow meter and a Gelman Model 1200-A, 2 inch diameter open filter hold,r. Each remote air sampling station consists of a line to the vacuum header with a valve, a Gelman Model 8224, 10-84 1pm air flow meter, a Gelman Model 1200-C 2 inch diameter closed filter holder, another valve and an offset penetration to the cell or remote area. 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. 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 hours the detector would see 165 cpm above background, not enough to cause an alal'ffl. The ~ir pump would then cycle to the other collector and the natural activity on the first collector would be allowed to decay for 11 hours. 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 hours in a -----*-- Appendix 9.33 concentfftion approaching the ,IQ hour M.P.C. If the concentration was 10-~c/cc the first detector would see 1100 cpm above background after 8 hours of collection and this would probably cause an alarm in the counting ratemeter. The unit will detect either a low level build up or a sudden burst of plutonium contamination and will alarm before the exposure of personnel exceeds the limits specified in 10 CFR-20. 1-Model AM-2A Fixed Filter Air Particulate Monitor. One ASC-1 alpha scintillation detector with ZnS phosphor. On6 LCRM-2M count ratemeter with one 3 cycle logarithm1c scale of 50-50,000 cpm. Detector is shielded by 2 inches of lead equivalent. The air pump is a continuous duty positive displacement industrial type driven*by a belt coupled, sealed ball bearing electric motor. Manually set alarm points with alert and alarm settings. Count,.~atemeter output is recorded on a ~j~tinuous strip chart recorder. Alpha air contamination of 10 ~c/cc and saq>ling rate of 5 cfm will result in 7 cpm build-up per hour. 5-Model AM-2A Fixed Filter Air Particulate monitor identical to the unit described above excert that the detector is a DGM-2 end window GM and the filter holder is modified to accept two filters in series, one particulate and one vated charcoal for collection of iodine-131. A concentration of 10-lO~c/cc and a saq>ling rate of 5 cfm will result in 350 cpm build-up per hour. Calibration and Maintenance of Continuous Air Monitors All the continuous air monitors will be calibrated monthly by analyzing the filters in the counting room and comparing the results with the count rate observed at the air monitors. Response of each unit to radiation will be apparent because of the natural activity filtered out of the air.

The system ia supplied by Packard Instrument Company, Irie~, La Grange, Illinois. The Model 314-EX2, as supplied, includes the following a 1-Tri-Carb Spectrometer, a two channel unit with two scalers, red and green, and an electronic timer. All three units have glow tube decade readout. Each channel has discriminator controls providing separate channels of pulse height analysis. Preset time control is in 20 steps from 3 seconds to 100 minutes. Pre!et cougts may be selected on either scaler in increments from 10 to 10. Preset time and both preset count settings interact so that whenever any limit is reached the count will stop, 1-Model ~-c Automatic Control Unit and 100 sample automatic changer, with two photomultiplier detectors, a monitor detector and an analyzer detector monitoring the sample well. The automatic changer and detectors ~re mounted in an eleven cubic foot freezer for controlled temperature counting. The automatic control unit programs operation of the sample changer. Controls may be set to count anywhere from 1 to 100 samples and the unit will recycle continuously if repeat data are required on a batch of samples. The unit may also be set for repeat counting of a single sample. If power failure should occur while a. count is in progress, the control unit will clear and ~peat the count automatically when voltage is restored. A manual over-ride button allows the operator to select any aample for a special count1 1-Model A Digital Printer provides a printed record of counting data on a strip of paper tape._ For each sample, the printer records sample number, elapsed time and counts on both scalers. In the operation of the liquid scintillation counting system, radioactive decay events occurring in the sample cause scintillations which are seen simultaneously by both photomultiplier tubes, giving rise to pulses at the phototube output. Pulses front the photomultiplier& pass through -preamplifier& and into three separate amplifiers. Pulses from the "Analyzer" phototube then go to the discriminator pairs A-Band C-D for pulse-height analysis. The "Monitor" phototube functions o~ly to determine whether a pulse is the legitimate result of a decay event or whether it arises from photomultiplier tube noise. Pulses falling between A and Bare fed to the red scaler and pulses falling between C and Dare fed to the green scaler. output pulses from all of the discriminators pass through the coincidence circuitry and only pulses occurring simultaneously in ~oth photomultiplier& are counted. This results in some loss of 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 gration rate of* an unknown sample may be detel'mined by counting the sample with the two channels ope~ating first separately and then in coincidence. Based on the approximatio~ that coincidence counting efficiency is a_product of the two.single-channel efficiencies, the integration rate is found from the equations dpm

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 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 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. ---- J( Appendix 9.51 1-Model RM-20BS Precision Log Ratemeter, identical to the RM-20B described above plus a ~pectrometnr input circuit for pulse height discrimination. Window width adjustable from 2 percent to 100 percent and threshold adjustable from 5 percent to 100 percent of full scale. 1-De Var Series R 300 two-pen recorder, Control Room Panel mounted ****-to record output from particulate and radioiodine stack monitors and to alarm if count rate of either unit exceeds tte preset level. The beta-ga11111a particulate monitor, with two inches of lead shielding around the detector, has a background of about 25 cpm. A counting rate of twice background is obtained at a concentration in the stack of about 1 x ~o-11 ~c/cc of mixed fission products. The Ganrna Scintillation Detector, wtth three inches of lead shielding around the detector, has a background of about 175 cpm for a counting threshold of 100 kev. The detector will show 100 net cpm after an exposure of 30 minutes to a concentration of 10-10 ~c/cc of iodine-131. Calibration and Maintenance of Stack Monitor The response of the stack particulate monitor to radioactivity will be apparent from natural activity as well as activity from the stack air stream which will be trapped by the filter paper. Calibration of the particulate monitor, relating detector counts per minute to microcuries per milliliter in the air ~tream, will be accomplished by analyzing a section of the filter in the counting room and comparing the results to the count rate indicated by the stack sampler. After the initial calibration, this check will be made only as the need is indicated but not less than twice annually. The iodine monitor will be calibrated quarterly by analyzing the activated charcoal filter in the counting room and comparing the results with the count r~te indicated by the stack sampler. The collection efficiency of the charcoal filter will be checked by _collecting a caustic scrubber sample independent of the stack monitor and comparing the results with the activity of the charcoal filter. This check will be made ~n each batch of filter paper received. -. *-----, -----~---* .....-=-.,.--*---....,.-*-*-.. ------:-----::-----.------...~ Appendix 9.53 Weather Monitoring Station l I

) Appendix 9.53 Weather Monitoring Station Two weather-monitoring stations are provided, one at 10 feet and the second at 200 feet above ground level. Each station continuously records wind direction, velocity, and ambient temperature. The weather-monitoring stations are. supplied by Science Associates, Princeton, New Jersey and each station consists of the followings 1-No. 4-120 Aerovane transmitter, a combined anemometer and wind vane in one unit. A three-bladed plastic rotor with a ~tarting speed of 2.5 mph drives a magneto which generates a v~ltage di~ectly proportional to wind speed. The streamlined vane houses a synchro whose rotor position is determined by the vane. The transmitter includes a filter to prevent radio interference and is permanently lubricated. 1-No. 4-141-5 Aerovane Recorder provides instantaneous readout of wind direction and velocity on the same chart. Direction data from 0 to 360 degrees is recorded on one side *of the chart and speed data from Oto 100 mph is recorded on *the other side of the chart. Each recording area is 4i inches wide. 1-No. 170 Stainless Steel sheathed temperature bulb and temperature recorder. Recorder is two pen with range of-50 to 110 Fin one degree divisions. The temperatures from both stations record on one chart. 1-No. 174 Aspirated Solar Radiation Shield to house the temperature bulb. Heat from the sun and from surrounding objects is excluded by the dome-shaped shield, by an inner and outer shield and by a surface orlanted baffle. A motor and blower, located at the remote end of the mounting al'lll, induce a forced ventilation. Tho recording charts for the two weather stations are located in the Control *Room Panel. -APPfndlx 9. . Stre .. Gauging and Sf!Pllnq

- t I ' i I ' ( -I INTRODUCTION [i,11 This document, which consbts of nine sections plus appendices presented In two volumes, represents a description and safety analysis of the Spent Fuel Processing Plant which Nuclear Fuel Services, Inc. wishes to build on the Western New York Nuclear Service Center near Riceville, New York. It Is the purpose of this Introductory section to provide a sunmary of the Information contained In the body of this report. Throughout the report the location of material ts tdenttfted by numbering paragraphs consecutively within each section; in this introduction the nunbering relate9 to the particular section being described. 1.12 Sections II, III, :nz, ll, and lZI describe the site plant, process, equipment, and supporting engineering systems, respectively. These descriptive sections form the basis for the safety analysis contained in Sections ll[[, Protection of the Public, and Section 2III, Protection of Plant Personnel. Section II describes the health and safety programs and the start-up plans for the plan:] :rr** Site *Description Geography 1 :21 . *: The faci 1 ity wi 11 be located on the Western New York Nuclear Service Center in the Town of Ashford, near Riceville, Cattaraugus County, New York, about thirty miles southwest of Buffalo and will be described as the Riceville Site. The site cont~ins 3,331 acres and the processing plant and waste storage facilities are located 3,000 to 4,000 feet from the nearest site boundary. The site is in the middle of a rural area ,f lcw population density -*an average of 90 persons per square mile within a 25-mile radius. The population has not changed within a 10-mile radius over the past 50 years, and the character of the land and community are such that it should not change materially over the next 15 years. There is no town within 25 miles of the site with a population in excess of 10,000. The nearest village Is Springville, 4-1/2 miles to the north with a population of 3,852, and the nearest major population center is the city of Buffalo, the city limits of which are 26 miles north of the site. The immediate area within four miles around the site ts divided between unusable rugged terrain and level fertile land used for farming. All roads through the . site will be used solely for access purp~ses and will be controlled by the applicant. There is a spur of the Baltimore and Ohio Railroad Company railr*oad used solely for freight traffic running through the site at a distance of 1,800 feet at tts closest point to any facility. 1.22 It ts suggested that the geographical factors are favorable. The exclusion area, as ts demonstrated in Section VII, is more than adequate to assure that the health and safety of the public wtll not be endangered by normal operation of the facility*or by any credible* accident. The population density beyond the exclusion area and population L 7 within a radius of 25 miles Is small, thus assuring a minimum exposure of the general public, if as a result of an unforeseen accident, activity should not be contained within the area of tne site. Meteorology 1.23 The area has a mean annual temperature of 4SF, an annual rainfall of 40 inches, and an annual snowfall of 80 to 100 inches. The prevailing wind directions are from the northwest In the winter and fran the southwest in the summer. The area to the northeast and southeast are even more sparsely populated than the average set forth in 1.21 above and the closest major population areas in these directions are approximately 80 miles from the site. The area around the site is seldom subject to persistent stagnant high pressure areas and poor diffusion conditions. Thus, the prevailing wind and diffusion conditions are favorable. Geology 1.24 The plant and the waste storage facilities are located on a plateau between two of the ravines which form tributaries flowing into Buttermilk Creek. The geological structure is bedrock overlain by gla~idi deposits consisting of a permeable glacial till, a much less permeable silty till, with sandy tills and various shales underneath. All layers have good ion exchange capacity for cesium and strontium. Hydrology 1.25 The site is an elongated rolling plain cut by ravines with tributaries leading into Buttermilm Creek. All of the tributaries on the site and, therefore, all ground water on the site feed into Buttermilk Creek within the portion of that creek contained wholly within the site. Applicant thereby has control over all surface drainage for the entire site by its control over Buttermilk Creek. At the site boundary, Buttermilk Creek empties int~ Cattaraugus Creek, which in turn flows into Lake Erie, 39 stream mfles from the site. No cities or villages downstream from the site rely on Cattaraugus Creek for their water supply, and there are no potable water sources or large water supplies in the immediate area of the site. 1.26 of 41 cfs. 358 cfs. Buttermilk Creek supplies dilution water at an average rate Cattaraugus Creek has an average flow ~t the site of 1.27 There are three aquifers on the site. One is in the surficial glacial till. Ground water movement in this formation is from 1 to 2 feet per day. On some parts of the site there is an aquifer located in sandy tills underneath the silty till. This does not exist on the plateau selected for the plant facilities. Finally, there is a deep bedrock artesian aquifer which ts situated well below impermeable layers at the facility location. The silty till, in which the waste tanks and the solid burial will be located, ts not an aquifer -. _, -*
( but 1t Is water saturated. Ground wat!~ movement In this very Impermeable layer Is calculated to be about 5 x 10 ft/day. It Is calculated 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 nearest ravine. 1.28 The good Ion exchange capacity of the soil, the slow movement from the waste storage facilities to the ravines, the existence of the ravines, and the fact that all ground water flows to a creek within the site render the site adaptable to an excellent monitoring system and allow excellent control over radioactive wastes stored on the site. Seismology 1.29 Western New York ts an area of low selsmlctty and the danger of earthquakes which might rupture any of the plant~s facilities Is minimal. The nearest feult to the site Is at a distance of 35 to 40 miles, and this Is more properly classified as a minor earth structure rather than a fault. Thus, the site presents no seismological problems. Sumnary 1.210 In sunrnary, the characteristics of the site are such that the health and safety of the public should not be endangered by operation at the site of the NFS chemical processing plant or by the storage of low or high level wastes. The remoteness of the site from population centers, the low population density for 25 miles beyond the site, the large exclusion area, and the meteo*rology, all are favorable factors to assure protection both from normal operation of the facility and from any credible accidents. The hydrology and geology are suitable to permit control of low level and high level wastes unde-normal conditions and In the event of :a: credible accident. The ease of monitoring water movements and exercising necessary controls, If excessive radioactivity developed, ls assured by the special conditions existent on the plateau on which these waste facilities will be located. I[[ *pJant Description 1.31 The plant site area, located in the center of the 3,331-acre exclusion area, contains 500 acres. Both areas will be fenced and conspicuously posted, and access will be controlled. The facilities consist of a process building, a waste tank farm, a waste burial ground, a temporary waste storage lagoon, an office building, and a warehouse. Office Building 1.32 The office building and parking for vtsl~ors and employees ts located at the entrance of the plant site area 4',000 feet from the process building and warehouse and 3,000 feet from tlie waste disposal ,. 11 I I I. I I I i 11 I areas. It Is thus remote fran the areas where nuclear materials are handled. Of the approximately 130 employees of the applicant, It Is estimated that approximately 30 will be employed In the office building. Process Building 1.33 The process building Is arranged In a Z with fuel receiving and storage area on one end and purified product removal facilities on the other end. In the middle are the mechanical and chemical process cells. On one side of the center line are offices, laboratories, control room, and related facilities. On the other side are shops, a utility area, and a warm equipment aisle. Fuel Receiving and Storage Area 1.34 The fuel receiving and storage area consists of a primary washdown area Into which the fuel shipping cask Is brought by rail or truck, a cask storage area, a cask decontamination pit, a cask unloading pool, a ruptured fuel Isolation pool, a fuel storage pool, and an underwater process pool. The cask unloading pool Is sufficiently deep to permit a mlnlmun water cover of 11 feet over the longest fuel element contemplated. The fuel storage pool has racks and equipment for handling each type of fuel presently contemplated. The underwater process pool *COnt~lns equipment for doing rough underwater cutting of non-active parts of fuel elements If necessary. Each pool can be segregated by removable gates. The spacing of the fuel and the crane and fuel handling fixtures are designed to prevent accidental crlttcaltty. Mechanical and Chemical Process Cells 1.35 The central processing area consists of a process mechanical cell and a chemical process cell. The mechanical cell ts 16 feet wide by 54 feet long by 24 feet high with wall of 6 feet of ordinary concrete or 4 feet of high density concrete. The primary purpose*of the mechanical cell Is to remove extraneous hardware from the fuel element and reduce It to small pieces (1 tn. to 2*1n.) which can be dissolved In the chemical cell. The area has vl~wtng windows and remotely operated cranes and manipulators. The chemical cell Is 16 feet wide by 107 feet long by 4s feet wide with walls of 6 feet of ordinary concrete. It has a remotely operated crane and periscopes, television, and viewing windows to aid in the use of the crane. All high level radioactive equipment requiring f.requelit maintenance which can be performed remotely Is located In this cell. Both cells are tied Into a central ventilation system. On each side of the central processing area are operating aisles containing most of the lnstrLments and controls. Under these aisles are aisles containing sampling stations. Underneath the Interior operating gallery Is a warm equipment aisle consisting of a series of shielding cubicles located below the floor level of the aisle. The cubicles have removable shield covers which permit mainance of p1.111ps and other mechanical equipment contained therein. I I , l I I Cl G Product Purification Area 1.36 At a 90 degree angle to the central processing area are the principal production purification and recovGry facilities. After dissolution of the fuel element In the chemical cell to form a process fuel solution, the solutions are put *through a Purex solvent extraction process which separates and recovers uranium and plutonium as nitrate solutions. This Is done In a series of perforated-plate pulse columns which have the necessary equipment for metering, transferring and Intermediate storage-of solutions-. Facflttles**for c*lean*up and recycle. of solvent are also Included. Product Hand) Ing Area 1.37 Adjoining the product purlflcatlon area are the product concentrating and packaging areas Including evaporation, Ion exchange and silica gel equipment for concentration, final clean-up and packaging of uranium and plutonium. The entire production purification and product handling area Is 128 feet Jong by 43 feet high by 16 to 22 feet In width. Warehouse 1.38 The warehouse Is located near the process building and will provide storage space for bulk ctiemlcals and other supplies, bird cages, shipping containers, equipment spare parts, and plutonium product solutions. 1J** Deta i 1 ed : Process :Des er i pt I on Basic Process 1.41 The plant Is a multipurpose plant capable of processing any type of fuel element from.which the fuel proper can be reduced to a nitric acid solution. This Includes all but one of the presently contemplated fuels from private nuclear power plants (graphite maxtrlx fuels). No fuel will be processed before It has been cooled for ISO days. The base line process Is a Purex solvent extraction system. designed for pr_ocesslng of low enriched H02 In stainless steel or zirconium al Joy tubes with a maximum throughput**of 1,000 kg of uranium per day. In addition, there wl11 be: 1. A head end dissolution treatment for the dissolution of zirconium clad fuels In HN01-HF mixtures, permitting a throughput of 600 kg of zirconium per day. Dissolution Is performed In stainless steel dissolvers with controlled additions of HF and HNO. Aluminum nltrat~ Is added to permit extraction of t.J uranium and to minimize corrosion. Stainless steel tanlcage Is provided for storing the wastes In acidic condition. I
- 2. 3. 4. A total dissolution scheme (Darex) for stainless steel cermet fuels. using mixtures of hydrochloric and nitric acids with a throughput of 230 kg of stainless steel per day. Special titanium equipment Is required In this head-end step which contains facilities for dlstlllatlon and recycle of the HCI. The dissolver Is located In a special cell over the process ..... mechanical cell and the rem11lnder of the Darex equipment ts located In a contact-m11lntalned cell adjacent to the first extraction cell. The Darex head-end rnay be replaced with electrolytic dissolution which ts simpler. The use of electrolytic dissolution wl 11 .Introduce no new safety questions. A direct nitric acid chemical dissolution process for aluminum or molybdenum alloy fuels. A deactivation process prior to dissolution for uranium carbide fuels or for those In which sodium Is present as a bonding agent. Receipt and Storage 1.42 The fu~I Is received In shielded. water-cooled,casks and Is hosed*down In the primary washdown area. After temperature reading. sampling of cask coolants and purging of gases Into the ventilation system. the cask Is placed underwater In the 44-foot deep unloading pool by a hand-operated overhead crane. The fuel Is removed and placed In storage baskets by remotely-operated equipment and the cask Is ~. transferred to a decontamination pit. The storage baskets are ferred by the storage pool crane to the fuel storage pool and placed In safe geometry racks. Any ruptured elements will be stored In sealed canisters. Hechanlcal*Processlng 1.43 When the fuel Is ready to be processed. It Is transferred by the storage pool crane to the underwater process pool fran where It Is transferred through a conveyor and crane to the process mechanical cell. It Is removed fran the basket by remote equipment and dried. The end hardware Is then cut off and the fuel pushed out of its casing. After inspdction it Is chopped Into small pieces In the bundle shear. This operation Is carried out under an inert atmosphere such as CO2, The resulting pieces of fuel are collected In chopped fuel canisters. If sodium ts Involved. deactivation of the sodium Is accomplished before removal of the chopped fuel fran the CO2 atmosphere. Then the chopped fuel canisters are removed to the chemical processing cell on a transfer cart through an airlock. -( ( (

Nitric acid and water are metered Into the dissolver from the solution makeup area so that the final solution contains no more than 7.5 grams per liter of U-235, a critically safe concentration In all geometries and quantities. Complete dissolution Is expected to take about 12 hours. The off-gas treatment Includes a down-draft condenser on the dissolver, a secondary condenser, a scrubber, Iodine removal on a silver reactor, and filtration through parallel filters. The off-gas Is then added to the general ventilation system for further filtration before discharge to the stack. 1.45 Vhen the dissolution of the fuel Is canplete, the solution Is cooled and Jetted to a 304-L stainless steel accountability and feed adjustment tank. The dissolver ts then heated to dry off the hulls, which are returned to the process mechanical cell. The hulls are Inspected and packaged and sent to the solid waste storage area. The accountability and feed adjustment tank Is equipped with heating coils, a condenser, air sparger, liquid level and specific gravity measurement, circulating sampler, and temperature measurement. After analysis and adjustment* of the a>ncentratlon and acidity of the feed, It Is Jetted to the partition cycle feed tank from wht.ch It Is fed to the extraction columns. Solvent Extraction 1.1'6 Solvent extraction Is done by a Purex-type process, which Is performed In the contact process area. The base-line fuel Is put through a partition 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 the major fission product waste stream of the plant. "The plutonium and uranium are also separated In this first extraction cycle Into two separate, partlelly d~conta~lnated, aqueous product streams. These two product streams are then separately put through additional solvent extraction cycles to complete the removal of remalnln~ fission products. 1.47 The uranlun and plutonlun product streams are first collected In the feed conditioner tanks for sampling, analysis, and adjustment of acid concentration. The streams are then put through additional solvent extraction cycles In which the product Is extracted Into an organic phase 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 plutonium through *one. I I I I .I a I ' 11 I ,! I I l l I I I I I I I I n,
. Product Purification and Concentration 1.48 The uranium product stream from solvent extraction Is collected I~ a product evaporator feed tank from which It Is Jetted Into one of l'WO evaporator tanks for concentration. The condensate Is collected In one tank and the concentrate In another. The concentrate Is subjected to a silica gel treatment for final decontamination. The product Is then placed In one of two sampling tanks, and after sampling and analysis It Is transferred to one of a series of storage tanks. Highly enriched uranium Is drawn from th*** tanks In small quantities and mixed with water to a concentration critically safe for shipment In tank trucks; the low. enriched uranium Is already at an acceptable concentration from a crltl~allty standpoint. 1.49 The plutonium product stream Is collect*~ In an Ion exchange conditioner 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 concentrate Is collected In one of three plutonium storage tanks, from which It Is packaged for shipment. _All of the packaging and shipping equipment Is enclosed In separately ventilated glove boxes. The shipping bottles are placed In secondary containers and stored In the product storage area In bird cages awaiting shipment. Solvent Recovery 1.410 The plant Is designed to reuse the TIP-kerosene solvent, which must be cleaned of fission products prior to reuse. To accomplish this, the solvent Is first washed with sodium bicarbonate and then with dilute nitric acid. Acid 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 subjected to an acid fractionation step to concentrate It Into a reuseable condition. Rework System 1.412 All waste streams will be sampled and analyzed prior to being discarded to the waste disposal system. In the event that the product In the waste stream Is above specification, facilities are provided to rework the wastes. They are recycled through a feed tank and a rework evaporator. The bottoms from this evaporator are pumped back to the feed adjustment tank to be subjected to further solvent extract I on. ( C C -** -Waste Hind 11 ng 1.413 Liquid wastes are placed In *tanks designed to contain ap~roxlmately 500,000 gallons each. The tanks are constructed In the *~up-and-saucer" design used at Savannah River. They are operated, however, according to the waste management procedures applied at Hanford. Spare tanks are provided so that wastes may be transferred to another tank should leakage develop. l.414 A general purpose evaporator Is provided In the tank farm area for reducing the volune of low level wastes. It Is backed up by an Ion exchange unit for the condensate. The overhead product Is expected to be water, sufficiently pure to be discarded to Buttermilk Creek. 1.415 High level, solid wastes, such as hulls, wlll be stored In the tank farm area In concret&*llned bins burled In the ground and manltored to assure that no water collects In them. Any seepage wl 1.1 be p1.1nped out and processed In the general purpose ev~porator.

Ventilation 1 .62 The plant has four ventilation systems which are separate from one another. These are: {1) the general building ventilation, (2) the process ventilation, (3) the process vessel system, and (4) the dissolver off-gas system. The systems are designed so that: (1) the total volume of air is kept to a minimum, (2) all air entering is mechanically or chemically cleaned to remove particulate matter and fumes, (3) air pressure to limited access areas is less than atmospheric and to process areas at an even lower pressure, (4) normal access openings are ventilated from the less active to the more active area, (5) gases from process and laboratory equipment are segregated to permit special treatment and close monitoring, (6) back-up systems are employed where desirable for reliability a.nd continuity, (7) distribution equipment contains volumetric control, isolation, diversion, and concentration, (8) toxic and radioactive aerosols are kept to a minimum, and (9) final exhaust to the atmosphere is accomplished at sufficient volume to insure dilution of irremovable gases and at sufficient height (202 feet above grade) to assure secondary dilution and adequate distribution to the atmosphere. The total volume of air discharged is 46,000 cfm. Fume hood and radiolaboratory exhaust, the process ventilation system, the various vessels and equipment pieces in the proc~ss area are separately vented to duplicated systems of preheaters, prefilters, absolute filters, and exhauster installations prior to release to the stack. The waste tank f.Jrm vent gas system cor.sists of two glass fiber-packed columns and parallel exhaust discharging to its CMn stack. Each system is separately adjusted automatically and has a spare absorber train with automatic start-up and phase-in. The duplicate systems are isolated by butterfly valves. All of the exhaust fans are connected to the emergency electrical system and will come back into operation within ten seconds and automatically start up if static pressure in an area drops below a preset point or if activity increases beyond a preset point. The entire system may be operated manually if desired. * }}
