The plant and process which have been described in detail in preceding sections are designed to operate so that, under all normal operating procedures, any discharge of radioactivity to the' environment will be well within the limits set forth in 10 CFR Part 20.

7.2 Radioactivity can be lost from the process complex at the fo!lowing points,

1. Stack

  • 7 .*3 Further, this plant and its site are shown to be so designed and located that, in the unlikely event of the

- moat sarious accident which could possibly be deemed credible, there will be no discharge to the environment which results in levels of exposure in excess of those set forth in Sections 100.ll(a)(l), (2) and (3) of 10 CFR Part 100; and further that steps can be taken to assure. that, even in the event .

of such an accident, the disch3rges to surface waterways at the site boundary canoe kept within the limits specified in 10 CFR Part 20 th!ough the use of reasonable correction measures after the accident or release has occurred.

7.4 The following abnormal events have been postulateds

1. The complete rupture of a waste tank releasing 600,000 gallons of high-level waste.
2. A criticality incident anywhere in the plant involving a total of 1019 fissions in a single buiat or a multiple continuing event totalling 1~ fissions. .

  • wind frequency *in per cent/octant The calculation has been carried out for both inversion and average conditions aver the range 1500 to 51,000 meters (see Appendix 7.7). The results of these calculations are presented in Table 7.7. The maximum concentrations are given for both the average and inversion conditions. For average conditions the maximum concentration occurs at the site boundary; under inversion conditions the maximum concentration ~ccurs over the range of about 4000 to 10,000 mei ers downwind from the stack. It can be seen that all of the concentrations are well within the MPC values with the exception of the Kr-85 concentration under inversion conditions. The inversion concentrations given are centerline concentrations and include no wind diverstty factor; they are not expected to persist for more than a few hours at a time. The yearly average concentration, which is permitted under 10 CFR Part 20, will not be significantly increased by these occurrances *
    • . 7.8 Although 10 CFR Part 20 contains no provision for limits on the . deposition of radioiodine on pasturage, the plant is designed to release iodine at concentrations lower than the MPC for concentration in air in order to protect those areas surrounding the plant site which are used for dairying. Using the long-period average concentration and a deposition velocity of _0.01 meter per second, ~he deposition rate has been calculated (Appendix 7,8). Since yearly average contentrations are used, it is reasonable to assume that the equilibrium. conditions are reac~edJ i.e. the rate of depos-ition equals the rate of decay. The south, southwest and northwest octants have the highest yearly average wind frequencies, ranging from about 19 to 22 per cent. Therefore, a wind frequency of 25 per cent per octant has been used in these calculations. It was found after the Windscale incident that a grazing area contamination level of l µc per square meter resulted in about 0.1 µc/liter of milk*.

Using this relationship the resultant activity levels in milk ha~e been calculated. The milk activity levels are shown in Table 7.8.

7.9 The Federal Radiation Council has established a Radioactivity Intake Guide for Iodine-131 of 100 µµc per day, b~sed on the uptake by children as the most sensitvie segment of the population. As can be seen from Table 7.8, the con-sumption of about five liters of milk per day from dariy cattle grazing inrnediately adjacent to the site boundary would be required to equal the level of intake as established by

  • this Guide. This rate lf consumption is higher than any that can be expected, probably by a factor of at least four. In additio n, no credit is taken for dilutio n (during processing) by milk contain ing lesser (or no) amounts of radioio dine or the fact that cattle are pasture d in Western New York State only about half the year.

Waste Storage Tanks 7.10 The design of ~le waste storage tanks has been discuss ed in detail in Paragraphs 5.50 through 5.56 and in Submission 1 date July 1, 1963. These t~nks are built in a "cup-and-saucer" design. Operating procedu res call for monitoring of the annular space between the tank and its saucer and of the water introdu ced under the tanks.

If there is signific ant leakage from the tank into the saucer, the entire tank content s Nill be transfe rred into a spare tank kept for that purpose . Thus, under normal operati ng conditio ns there will be no loss of activit y from these tanks. c<<~,.- t J.r ..,.\c,.~,lt. o,\;;;-,

1 Storage Lagoon 7.11 The very low-lev el wastes from this process --

overheads from acid fractio nation, solvent wastes, and

  • miscella neous wastes- -can be put through the gene.ral purpose evaporator and the overheads from this can be put through ion exchange ~olurnns if necessa ry. It is expected that the normal activit y content of the overheads from the general purpost!

evapora tor -will contain about 10-6 µc/cc . of activit y. This can be further reduced by a factor of 30 by the use of simple, non-reg enerated cationi c ion exchange r~sultin g in a concent-ration of 3 x 10-8 µc/cc. The expected volume of these .

wa*stes is 40,000 gal/day . The average availab le flow in

  • Butterm ilk Creek is 41 cfs which is equal to 2. 7 x!_07 ga.1/day.

Thus, the availab le on-site dilutio n factor is 6.8 x 102.

In Cattara ugus Creek an additio nal dilutio n factor of about 8.5 is availab le. The concent ration in Cattara ugus Creek would be expected to be about 10-lO µc/cc. Furthermore, the residua l activit y in this stream will be largely Ru-106 and I-131 with some ~-Nb-9 5. The MPC's for 4these isotope s are 1 x 10*5~ 2 x 10*, 6 x 10-5, and 1 x 10* µc/cc rather than 1 x 10- 1 for unknown activit ies when radium is absent.

Therefo re, the availab le factor of safety is 4about 103 with-out any analyse s of the effluen t and about 10 if we choose to carry out specifi c fission product analyse s on this effluen t stream. This stream will also carry about 130 curies per day of tritium since there is no known way to process it to remove the tritium . The concent ration of tritium on-site in

-Butterm ilk Creek will average 1.3 x 10-3 µc/cc. The on-site MPC is 10-l µc/cc. In Cattara ugus Creek the tritium

  • concent ration is expected to average 1.5 x 10-4 µc/ccJ the MPC here is 3 x 10-3 µc/cc.
  • Revision 1, Oct. 29, 1962 Revision 2, Aug. 20, 1964

7.12 This low.le vel .stream can be discha rged direc tly to Butte rmilk Creek and the level of activ ity at the site boundary will remain well within the MPC level s of 10 CFR Part 20. In additi on there will be a serie s of lagoons availa ble for use as an emergency holdup area. Their use will permit time for the decay of short er-liv ed isotop es and will allow the adsor ption on the soil of some of the I longe ~live d isotop es. The low level waste streams from the plant ~isch arge into the interc eptor , a concr ete pit of 50,000 gallon s capac ity, ..ich is design ed for batch ing of waste s. A valved interc eptor drain lice will permi t collecOion of one days outpu t from the plant which will then be sampled for gross alpha , beta, ganma and tritiu m. The pH of the sample w,ill be checked and the interc eptor conte nts neutr alized if neces sary ~o pH to 6 to a. A line is availa ble for pumping the interc eptor conte nts back to the plant for furthe r proce ssing. Normally, after sampling, the inter -

cepto r drain valve will be opened and the conte nts allowed to drain by gravi ty to the first holdin g pond, a 300,0 00-gallon settli ng basin vlith a hlgh level overflow to the second pond * . The second and third ponds each have capac ity of about 2.3 millio n gallon s. Between the second and third ponds will be a high level overflow and a valved drain line about 18 inche s above the bottom of the pond. A valved drain 0

line from the third pond will discha rge to the creek . The ete capac ity of the ponds above the overflows will allow compl holdup of 100 days outpu t from the plant .

7.13 In view of the facto rs of safety availa ble, no hazard will be prese nted by the routin e handl ing of this aspec t of the opera tion.

Buria l Ground 7.14 Two types of wastes will be buried in the ground in conju nction with the opera tion of this plant . One is low-

  • level solid trash of all sorts coming eithe r from the plant opera tion itsel f or shipped in for buria l from off -site users of radio activ ity. The other is high-levP.l solid trash in the form of leache d hulls or equipment discar ded from the ered plant . Activ ity assoc iated with the former type is consid to be "avai lable" in the sP.nse that it could be leached out of the waste if it were conta cted with water . The radio activ ity assoc iated with hulls and discar ded ~quipment, Revision 1, Aug. 20, 1964

on the r,ther hand, is not considered to be "available". In the case of the hulls, the radioactivity is induced in the hulls themselves which are either $tainless steel or zirconium. Both of these metals are highly refractory and and would not be expected to corrode in the burial environment to any significant extent. They will have been carefully l leached in bolling nitric acid prior to burial, inspected, and an aliquot analyzed to assure that significant quantities of fuel values ar~ not being discarded with them. Equipment to be discarded will have been exhaustively decontaminated in place before bringing it out of the cells and it will then be further decontaminated in the Equipment Decontamination Room before it is buried. Hence, significant quantities of "available" activity is not expected to be associated with this type of waste either.

7.1~ Burial .of both types of solid waste will be done in the silty till described in paragraphs 2.17 through 2.25 and 2.41. We h~ve now had considerable experience in working with this material in various excavations in the course of constructing the plant and in the operation of a low-level waste burial *operation for wastes of the first type described in paragraph 7.14. From this experience it is possible to accept the very low permeabil*i ty figures which were obtained during the subsurface investigations reported in Section II.

Therein a calculated *horizontal flow rate of 5 x 10-5 ft/day was reported.. Since we expect to carry out no burial operations within...100-.feet of any ravine, -this calculates to something over 5000 years for any leached activity reach the ravine. Further this silty till has been shown to have good ion exchange capacity for the longer lived isotopes, Cs-137 and Sr-90. Thus, we expect the natural defenses~-* this material to cont~in completely the activity buried in it.

7.16 Silty till does not, however, act as a natural ion exchange material for ruthenium. This is a relatively short-lived isotope, however. For the sake of illustration assume that a curie of ruthenium were to escape from the burial site and begin to work its way toward on of the ravines. Further .assume that discontinuities or chemical reaction of the waste with the soil should increase its velocity by a factor of 100. It would still take over 50

. years for the activity to reach the stream. In this period of time the curie ruthenium would have decayed to 10-l5 curie.

  • The yearly flow in Cattarau~us Creek averages 3.5 x 1013 cc.

Thus, for each curie/year which was leached from the burial ground, the concentration in Cattaraugus Creek would be 3 x 10-23 ~c/cc. The MPC is 10-5 pc/cc. .

Abnormal ~eratio ns 7.23 In Paragraph 7.4 five abnormal events were hypothe-sized. These *events range from the unlikel y to the incredi ble but they delinea te, we believe , the upper limit of any cat-astrophe which could occur in this plant and its related facilit ies. None of these acciden ts would result in levels of exposure to the general public exceeding the quide limits for gaseous emission suggested in Section 100.11 of 10 CFR Part 100, and further there is reasonable assurance that liqiud dischar ges at the site bounda11 could be kept within the concen trations for drinkin g water purpose specifie d in 10 CFR Part 20.

Loss from High-Level Waste Tanks 7.24 Careful measures have been taken to ensure the reliabi lity of the high-le vel waste tanks, to provide multipl e means of detectin g any leakage in the unlikel y event that any defects should develop and to minimize the effects on the environment of such leakage . ...'

7.25 There are several methods of detectin g leakage from the waste* tanks barrier s between the stored waste and the environment. The tanks have been e.quipped with liquid level measurement systems which are accurat e to 1/4 inch or about 700 gallons .

  • The tanks are located within saucers and each saucer is equipped with a liquid monitoring system.

Each tank and saucer is contained within a reinforc ed concret e vault; the vault in turn is constru cted upon four feet of graded gravel into which water is introduced for the primary purpose of maintaining the moisture content --and thus the bea~ing propert ies--of the underlying silty till.

There are eight wells located within a foot of the vault which go down into the gravel area and through which the level of the water is measured and from which samples may be drawn to determine if there has been any leakag*e through the first three barrier s. If there sho~ld have been any large penetra tion of the first thr~e barrier s, it would be possibl e to retriev e the activit y with relativ ely little dilutio n by pumping out of the gravel area thro,*;!l any of

  • the eight wells. This 3rea thus represe nts the forth barrier to the escape of activit y.

  • tanks 7.26 Th* local environment provides two additional

~nlen to the **cape 6f r1dioactivi ty from the al te. The

  • r* located in the approximate center of a peninsula with a thick layer of aUty till. rt has been shown ~at

~h* perm..blllty of this silty till la so low that essentially complete containment would be expected of any waste that did

.-.cape the first four barriers. The till, then, is a fifth and most important barrier. The aeninsula is bounded by Erdman Brook and Quarry Creek. U&iS geologists who did the survey work on the site assure us that any radioactivity which escaped either onto or into the ground on this peninsula would eventually have to show up in one or the other of these creeks lf lt were not adsorbed on the soil by ion exchange.

At the confluence of these two creeks there is established a sampling *st&tlon to detannine again that activity has not escaped from the site. The average yearly flow at this point is about 2 cfs. While it would be expensive, it

~ould not be impossible to collect the total flow at this point and pump it bac~ up to the plant site for additional processing if this should prove to be necessary. This represents the sixth barrier. There is still a final sampling of th~ ditcharge in Cattaraugus Creek at the point where the effluent leaves the plant property. This will provide the legal record of the plant discharges.

7.27 A spare tank identical. to the working tank is provided so that in case the working tank begins to leak the contents may be transferred to the spare. Initially there will be a lal sparing ratio. It is .contemplated that during the first 1~ years of .operation of the plant two additional working tanks will be built and that the spare will serve all .three. Th~ eveotual sparing ratio will be dictated by plant experience.

  • 7.28 c;;,~~that a waste tank could be ruptured only by sabotage or*by a major earthquake. The former is outs!de the scope of the requi rements of this review. The latter has been shown to be highly unlikely (see Paragraphs 2.46 through 2.48). In the event that a tank shbuld rupture, however, the combination of the vault, the gravel area and wells, and the impermeability of the surrounding silty till can be expected to maintain the tank contents within the iamedlate area for a long period of time. There would be more than ample time to arrange a temporary piping system to permit pu:nping the waste solution from the tank, the saucer, or wells into the gravel, into the spare tank.

Criti c~llt y Incid ent Anywhere in the Plant 7.30 7here have been eleven criti calit y incid ents in solut ion systems.* Eight of these have resul ted in a total number of fissio ns ranging from 4 x 1016 to 1.3 x 1018. Oie, that at Idaho Chemical Processing Plant in October, 1~9, resul ted in 4 x 1019 fissio ns. Except in one case in which there wa, some warping of a tank bottom, none of these resul ted in any physi cal damaga. The assumption is made her~ that a criti calit y incid ent producing 1019 fissio ns in a singl e burst or 1()20 fissio ns in a repea ting incid ent is experienced anywhere in the plant and that the entir e produ ction of noble 9aseous fissio n produ cts plus 1/3 of tht iodin es (from 1020 fissio ns) are lost. The value ofat 1019 fissio ns is chosen to conform to calcu latio ns made Savannah River suggesting this value as the upper l~~itfissio of a singl e burst . These same calcu latio ns suggest 10 ns as the resul tant of a maximum repea ted burst . It*w ill be ohown that the limit ing problem with this incid ent is not a publi c nnel prote ction problem but rathe r the exposure of in-pl ant perso to pene tratin g radia t-ion at the time of the burst . For annel repeating incid ent there would be time to evacuate perso ion after the first burst and the exposure to penP.trating r adiat burs t.

can be considered equiv alent to that from a 1019 fissio n This is considered in Paragraphs 8.26 and 8.27. Insof ar as the general publi c is concerned there is no ~azard from the iaaad iate radia ti.on at the time of the burs t. It ,.s well of

  • ~tab lishe d that the limit ing cond ition in an occurrence this type is the thyro id dose from the iodin e isoto pes re-l eased. There fore, this event is analyzed on the basis of thyro id dose to a person on the perip hery of the site, at Sprin gvill e, and at Buffa lo. All three are calcu lated for the average and inver sion cond itions speci fied in Table 7.5.

In the case of Sprin gvill e and Buffalo the total popu lation dose ls calcu lated and expressed in man-rem.

Wlth one excepti on, the p~ak activit ies have been assumed in calcula ting the popunticm- dose. This procedure ls conserv ative but by a relativ ely small amount over the time periods involve d. The one exception is the activit y of iodine-134 at the time it reaches Buffalo under inversio n conditi ons.

The tranait time in this case ls so large in relatio n to the half-li fe of iodine-134 and its precurs ors that its activit y level was found to b~ ner*igi ble compared to the remaining iodine isotope s.

7.32 Th* off-sit e doses have been computed assuming that the iodine 11 release d from the stack instanta neously . The to~l inhaled activit y has been calcula ted using Equation 7.7a for short-te rm center- line concen trations .

Extrapo lation to 50,000 meters is questio nable, but gives a fair estimat e. The results so obtained are given in Table 7.32a.

Then using the approximations suggested in 10 CFR Part 100 for the thyroid dose from each of these isotope s, the total rem p,r person and the fraction of the 300 rem referen ce value are calcula ted 'for the three locatio ns and for .both typee of meteorology. Total man-rem values have also been calcula ted.

These date are presented in Table 7.32b. Calcula tions supporting the numbers shown in these three tables are given in -Appendix 7.32. It can be seen that in no case is the referen ce value used for evaluaton of reactor sites exceeded or even closely approached. The highest value indicat ed, a 1.95-rem/person dose in Springv ille under i nversio n conditi ons, is not expected to be encountered since it is the opinion of meteoro logists (see Paragraph 2.13) that an inversio n aimed at Springv ille would be caught and held in the Buttermilk-Cattaraugus Valley systems. Even t ~is value is only about 0.7 per cent of an emergency dose of 300 rem.

It is furthe r assumed that all five elements are defec tive and, thus, that some gaseous activ ity can escape from the element.

7.34 Calcu lation s suppo rting this sect ion are shown ~in

    • Appendix 7.34. The beet releas ed would raise the temperature of the water in the storag e pool only about 16F even if the pool water coole rs failed to opera te. There fore, there is no danger that the water level in the pool would drop sign-ifican tly and consequen~ly the shield ing provided Ly the water would preve nt any hazar~ from increa sed radia~ion levels from direc t radia tion.
  • EBWR defec t test studie s have shown that the fracti on of noble gaGaous activ ity lost per second from a defec tive fuel element is about 4 x 10-s. This same test showed that the iodine loss was at least an .order of magnitude less than this. The total inven tory of gaseous activ ity ir, the five fuel elements assumed to be i nvolved in this incide nt and the amounts which may reasonably be lost from the fuel pool water are shown in Table 7.34. These ts quan titi,s of iodine isotop es are much less than the amoun which ~ave alread y been *shown to be readi ly tolera ted by this environment (see Paragraphs 7.30 to 7.32) . Consequently the iodine releas es resul t in less hazard than has alread y been shown to be accep table. The releas es of kryptons are also much less than those which have. alread y been shown to be withi n MPC. Simil arly, the xenon-133 discha rge resul ts in conce ntrati ons under the worst *condt ions of only 0.01 MPC.

  • Using the method employed in Paragraph 7.7 (Equation 7.7a)

~h* concentration of xenon-138 at the site boundary under inversion con~itions is f.4 x 10-6 p.c/cc. No MPC for this isotope is given in either 10 CFR Part 20 or in NBS Hand-book 69 but it would not appear that this would result in any hazard. This event can, therefore, be tolerated without exceeding published feiPC' s_.

Chemical Explosion 7.35 The a*ssumption is next made that a vessel containing one full day's charge of fuel in solution suffers an explosion which ruptures the vessel distributing the contents through-out a cell and putting some fraction of the contained solution into the ventilating system. The ventilating system will 8ithstand the rupturing of a tank. However, there might be some plugs or windows loosened. So long as ventilation is maintained air flow should remain into the cell except for the instant of the explosion. In analyzing this event some assumptions contained in "Radiochemical Facility Hazard Evaluation", by E. o. Arnold, A. r. Gresky, and J.P. Nichols,

~L-CF-61-7-39, July 10, 1961 are used. This is a very similar analysis of a completely analogous situation to that considered here. The assumptions are made therein that aerosols pene-trating high-efficiency filters will contain 0.14 mg/M3 of material with the same concentration as the original dispersed solution and that the MPC for mixed fission products is 6.6 x 10*9 a,.c/cc. The ventilating air passing through the fllt.e rs of this plant amounts to 32,000 cfm or 900 M3/min.

Then 0.14 x 900 or 12~ mg/min of the original solution may be assumed to pass through the filter. w~ further assume that the gaseous activity has already been released and that in twenty .minutes the ventilating system will have picked up nearly all of the gross activity that it is going to; Under these conditions about 2.5 grams of solution will be released.

The maximum activity to be expected in the plant is about 700 curies per liter or 0.45 curie per gram for a total discharge of 1.1 curies. Following the methods of Paragraph 7.7 the poorest value of X/Q (at a distance ~f abou~ 5,000 meters) ls 1 x 10-5. Q is equal to 1.1 3600

  • 3 x 10-4 curie/sec.

The X

  • 3 x 10-9 p.c/cc. This is le s than t e MPC for mixed - :; ..

fission products assumed by ORNL in the above report and it would appear possible to accept this particularly untoward accident.

  • There would be, of course, a big cleanup job in the cells. This would be undertaken according to methods outlined in Paragraphs 8.8 and 6.54 through 6.56.

failure of Iodine Removal Equipment

. 7.36 Finally it is assumed that the silver reactors and other iodine removal equipment all fail and that this ls not discovered for a period of one day.

If the entire charge of iodine-13 1, 1.7 curies, were to be lost during a day the value of Q is 2 x 10-5 curie/sec . Under worst conditio ns (at a distance5of about 5,000 meters) the poorest value of X/Q is 1 x 10- and the concentr ation of iodine-13 1 at this point would then be 2 x 10-10 p,t;/cc.

VIII PR0rEC1'I0i Of PUNT PERsmHEL l>e*lf! Criteria 8.1 The design criteria and the operating rules of the N1S plant have been set up so that the plant .will conform to th* rules and regulations specified in 10 CFR Part 20, Standards for Protection Against *Radiation.

8.2 The plant will have an across-the-board industrial safety program (see Section IX) aimed at reducing accidents of all types. It will maintain a con~tant program designed to increase .tM s,afety morale of all of its personnel, both ln the area ~f normal industrial safety and in that of radistion safety.

8.3 The radiation safety program is designed to protect the plant personnel froms

a. external radiation,
b. inhalation, *
c. ingestion.

All three have been taken into consideration in the design of the plant. They also dictate the conditions under which the plant will be operated. In subsequent paragraphs each of these areas is discussed in detail to demonstrate that the plant as designed can be operated in accordance with the provisions of 10 CFR Part 20. In addition, the accidents which were hypothesized in Section VII are reanalyzed from the standpoint of personnel in the plants and some less serious but more probable events are discussed from the view-point of pers*onnel protection.

  • Protection from External Radiation 8.4 The primary protection for t he worker from penetrati ng radiation is to interpo1e sufficient shielding between him and the radioactivity at all times. The plant shielding has been described in some detail in Paragraphs
  • 6.~9 through 6.65. The shielding has been designed so that, when the most active unit which ~ould be in any particular section of the plant is present, . the radiation level on contact outside the shielding in a normal access area would be 1 mr/hr. In many cases the point *of contact will not be readily accessible. to personnel and the percentage of the time that the shielding wall is subjected to the maximum activity level 11 small. The shielding design has been based on a "design"

A shipment will be surveyed befo:re it is sent out.. It will be survey_ed again upon arrival at the plant. Before the carrier is opened, lt is placed under sufficient water (see Paragraph 3.7) so that, as a fuel element la removed. there will be at least 11 feet of water over the to~ of the longest type of fuel element. Movement of the elements ln the storage pool ,and their storage are also conducted under at least this much water. Transfer to the PII: ls done remotely under water and back of concrete ahleldlng. The mechanic1l operations in the PMC and GPC are carried out remotely back of. concrete shielding. The transfer to the CPC ls handled remot4!ly. All operations ln tho CPC are remote. Transfers to the remaining contact-maintained cells

  • are fluid transfers carried out remotely. All operations in the enti:re process, therefore, are carried out behind shielding until product ls decontaminated to the point where external radiation ls no longer a problem. Plutonium products containing high concentrations* of Pu-240 will be placed semi-remotely into con'tainers with suffic.i ent shielding so that they may be handled safety.

J 8.6 Sampling ls an operation which can contribute significantly to exposure of personnel. The sampling systems, which were described in detail in Paragraphs 6.22 through 6.36, have been designed to permit most of the sampling to be carried out compl~tely behind shielding and to provide working back-ground of l mr/hr or less. Many dilutions will be made inside the shielding and only the diluted analytical sample will be

  • brought out. This will reduce considerably the potential for spillage and also the resultant exposure in the event of spillage.

8.7 In order to maintain the background levels in the plant at design levels, it is necessary not only to have adequate shielding but also to maintain strict controls to prev~nt spillage. -This is done fir.st by keeping the activity back of the shiolding--there are no planned withdrawals of activity except for the samples, many of which, have been already dlluted1 second by a careful and continual radiation survey program to detect areas in which there may have been an inadvertent introduction of activity1 and third by a prompt and imnedlate cleanup of such areas at the same time deter-mining the cause of the event and corr*cting it.

Under all normal opera ting cond itions no proce ss activ ity is expected to escape past the first two barri ers and into the opera ting areas .

8.11 There will be a system of fixed air samplers backed up by a program of air monitoring with porta ble air monitors to assure that the air in the working area does, indeed, remain free of activ ity. This monitoring program has already been descr ibed (see Paragraphs 6.66 through 6.76) . The monitors will have audib le and visua l alarm s set to opera te at the lowest pract ical level so that reme dial actio n may be taken befor e any consi derat ion of evacuation is nece ssa_ry.

There is, however, an infre quen t cond down whereby the disch arge from a stack may come direc tly upon the stack . Under these cond itions the amQunt of .

dilut ion could be small. A calcu latio n is shown in Appendix 8.12 for the normal iodine-131 disch arge. This shows the conce ntrati on of Iodine-131 at the stack exit latio with no dilut ion at all except that affor ded by the venti n air in the stack itsel f. The conce ntrati on of iodin e disch arged from the stack would be 6.7 x 10-8 ~c/cc which ls onlyCFR a facto r of 7.~ highe r than the. occup ation al MPC of 10 Part 20.

I Ingestion

  • 8.14 The control of the problem of ingestio n of radio-activit y ls largely one of developing <<ithin the workers good safety morale and habits of persona l hygiene and of providi ng them .with adequate protect ive clothin g, devices , and monitors to facilita te the execution of the program. It ls a problem which has ~~en dealt with routine ly at all of the present ly operating chemical process ing plants of the AF.C without creatin g any serious hazards .

The medical history will be aimed at not only past illnesses and injuries but particular attention wlll be pald to history of past radiation exposure, al~ergies, blood dyscrasias, tumors, and any evidence of emotional instability. The laboratory studies*

  • .on all applicants will consist of a minimum of complete blood count, serology, urinalysis, chest X-ray, and vital capacity determinations.

~.ach employee will h~ve a complete physical examination yearly. A complete blood count will be done twice yearlyJ clinical urinalysis monthly. Bio-assays will be done on an

  • across-the-plant sta~lstical survey" plan and follow-up examination, as this survey may indicate. The pre-employment physical examination and laboratory studies will be repeated on each individual leavirag the employ of the company.

A dispensary will be maintainP.d for care of ordinary minor on-the-job injuries. There will be facilities for intensive first-aid care of severe* injuries such as burns, fractures, and gross contamination with radioactive material. Inrnunization against tetanus will be routine for all employees.

Close liaison with the Health and Safety Department will be maintained . The medical director will assist in health and gafety training and indoctrination o He will review with the superintendent of health and safety all industrial radiation exposure recordsJ air, water, and plant radiation survey records. He will cooperate with the superintendent of health and safety in plant inspections.

8.19 As expla ined in the foregoing paragraphs we

~"tic ipate no diffi culty in conducting the normal operastion of this plant withi n the framework of perm issib le levelon of exposure. It remains in the remainder of this secti to analyze the consequence to employees of ac~id ents.

  • Analysis of Accidents 8.20 In Paragraph 7.4 five highl y abnormal hypo thetic al incid ents were proposed and the effec t
  • of these upon the publi c was considered in Paragraphs 7.24 through 7.37. These same incid ents are now considered with refer ence to the plant perso nnel.

Tank Rupture 8.21 It has been shown that the soil in which the tanks will be const ructe d in quite impervious and that the liqui d from a ruptu red tank would be held in the iaaed iate vicin ity for some perio d of time. It is proposed that the waste be trans ferre d into one of the spare tanks as quick ly as possi ble. The type of actio n envisioned would involve pumping the solut ion into a t spare tank probably through temporary lines which migh be laid overground with only a minimum of shiel ding.

The layin g of this pipe would not requi re personnel exposure except for the connection into the ruptu red tank. This would be done by lowering a flexi ble hose into the tank through one of the spare nozzl es on the tank. If neces sary, such an opera tion could be d accomplished from back of a temporary shiel d const ructe outsi de the radia tion *field and pushed into place wi th a payloader or crane . If the earth shiel d remained intac t, no addit ional shiel ding would be requi red. If the sary condenser system was inope rativ e, it might well be necesy-

. to carry out this opera tion with the prote ction of suppl air masks. The trans fer system would probably be set up with two pumps in the system in an effor t to avoid any maintenance on the pumps durin g the trans fer opera tion.

The pumps would be opera ble from outsi de the radia tion field .

8.22 Maintenance of the pumps, if requi red durin g this opera tion, would certa inly entai l opera tions in a high radia tion. In the trans fer set-u p a tee would be ln1er ted upstream from the pumps so that the lines could be flush ed and decontaminated somewhat befor e such

  • Revision 1, Aug. 20, 1964
  • maintenance would be attempt ed. It would have to be done from behind a portabl e shield. In the case of so serious a problem as this there would be no questio n that oper~ti ons of the plant would be shut down and all availab le exposure time would be used in solving this probl*em. Supervi sory personnel to the highest levels and individ uals from other plants operated by the company--those who receive no radiatio n in the course of their work--could be brought in if necessa ryo No individ ual, however, need be exp,>sed beyond permiss ible levels.

8.23 Most of the exposure associa ted with this inciden t would be in cleanin g up afterwa rd. Dismantling the highly contaminated lines, pumps, and valves and disposi ng of them would certain ly require operati ons in high radiatio n fields. However, the need for speed would no longer be present and enough time and people would be used to assure that the task was accomplished within the permiss ible radiatio n exposur es.

Critica lity Inciden t in Plant 8.24 This inciden t, discuss ed in Paragra phs 7.30 through 7032, assumed that the ventila tion system remained in working order since that situatio n results in the most iamediate and complete dischar ge of the 9aseous isotope s to e the environment. In that event the air inside the plant would be completely safe, as evidenced by the calcula tions shown in Appendix 8.12, in all cases except that of the unlikel y recycle . In Appendix 8.25 it is shown that if such a downdraft occurs under average conditio ns the amount of dilutio n will amount to a factor of about 500 0 If it occurs under inversio n conditio ns the dilutio n factor will be about

~. For the purpose of this calcula tion the dilutio n is taken as 10. It is further assumed that during the course of the entire dischar ge (assumed to be 10 minutes) the downdraft will be centere d precise ly on the air intake ten percent of the time. It is also assumed that some personnel are exposed to the resultin g concent ration* for the entire ten minutes and that they are so preoccupied with renderin g assistan ce to other p~rsonnel or are otherwi se so upset that they did not make use of the availab le supply- air equipment.

Under these circumstances they would be exposed to the concen trations and receive the thyroid doses shown in Table 8.24. These calcula tions are also shown in Appendix 8 .,25 0 The total thyroid dose is less than the dose suggested as an emergency guide in 10 CFR Part 100.

a.~ There la no r1a1on to assume that the events which could lead to a criticality incident would al10 lead

.to ahuttlrig down the ventilation 1ystem. There may be, however, a iaall probability that the two events might occur 1laultaneou1ly. The possibility is a difficult o~e to analyze since the amount of li,akage of activity from the cell would be expected to vary considerably depending on the conditions. If th' supply air remains on, the exterior of *the cells .would remaln ' at a higher pressure tlijln the cells and little, if any, leakage should occur. If both the supply air and the exhaust go out, there may still be a little negative pressure in the cells due *t., the natural draft of. *t he 65-meter stack. If the static pressure in the cell becomto equal to that outside the ce-lls, some leakage wc,uld occur but it should not be large since any leakage path would be tortuo~s. 'There would not seem to be a mechanism whereby th~ cella would reach a higher pressure than the surroundings. Failure of the ventilation system will activate

  • an alarm which :will require evacuation of the plant unless counte%111anded by plant supervision. We conclude, therefore, that *tf a *critical.tty incident were to occur coincident with a failure of the ventilating system, the plant would be evac~~ed long before anyone could receive a significant dose from inhalation.

8.26 The most* tmportant aspect of protection of plant

  • personnel in connection With a criilcality incident is to assure th~t no one rec~ives a serious dose of penetrating
  • radl~tion at the time of the incident. The first line of de{ense -is, ~f course, to prevent the occurrence of the incident. Gre~t care ls being exercised in -the design of this plant and in the setting up of its operating procedures to ensure tha.t
  • a
  • crl ticall ty incident does not take place.

The whole subject of crlticality control throughout the plant ha* been pr,sented in detail ln the final paragraphs of Section vi; We believe that we have reduced the probability of such*~ incident to an absolute minimum. However, there have been eleven such accidents in solution systems. Every

  • mijor site save one has had one. There have been five incidents in metal-air systems at Los Alamos.

8.27 An Olk Ridge study* has calculated the prompt neutron and gamna dose at the outside of a normal concrete shield from a nuclear reactor of 1018 fissions and these data are shown in Table 8.27. They can be used fqr a 1019 fission event by direct ratio. Th9 concrete shielding walls

It will certainly be possible to evacuate this room ln less than a minute and an event such as this would be iaaediately obvious to anyone in the room.

Presumab\y there would b~ a visible flash. Monitors would trip and alarm, and the fuel pool itself .would be visibly agitated. After evacuation, personnel could put pn supply-alr equipment in other parts .of the building before re-entering to take remedial action.

Chemical .Explosion 8.30 In .Paragraph 7.3~ a chemical explosion is assumed which ruptures a tank containing an entire day' s charge .of activity .les~ the gaseous activity (sine~, in orde~ to have the full day's charge in solution, it will have to have been through the dissolution step during which the gaseous ac~ivity ls lost). The cell ventilation system has *been designed to withstand *the effects of sucn an explosion. So long as the ventilation system is maintained, no activity ,hould get out of the cell in which the explosion took place e~cept s~e that would be lost during the period of oyerpressure following the. explosion. This period is estimated to be about one second. The calculations of Appendix 8.12 show that,' for all conditions except a direct recycle of stack discharge into -the air intake, there will be negligible concentration of ~ctivity in the building air.

In the unlikely event that such a recycle and an explosion should coincide and using o calculative method analogous to that shown in Appendix 8.25, the concentration of unfiltered solid* activity at thr tnroat of the stack would bea 0.12~ g/min x 0.45 curie/gram x 106 pc/cc /

  • 32,000 cfm x 28317 cc/cf
  • 602 x io-5 p.c cc As in Appendix 8.25 a dilution factor of 1/10 from stack to intake and a frequency factor of l/10 were used ~ The resulting concentration in the building would be 6.2 x 10-7 µc/cc.

This is about 100 times the MPC assumed by Oak Ridge for mixed fission products as aerosols and it implies that about 25 minutes would be available for evacuating the plant. This ls more than adequate.

As in the discu ssion of Paragnph 8.25 we find this si'tua tion diflic ult to analyze and for the same reaso ns. In this case it is certai n that the cell would be pressu rized for a short time, perhaps sever al seconds, and that du1ing this time some activ ity would escap e. If the buildi ng venti lation system were iOt functi oning , the air in the buildi ng will be essen tiallyhigh stagn ant. In the ianed iate vicin ity of the cell quite concentrations can be hypothesized depending on the assump-tioni chosen. However, it seems diffic ult to hypothesize a mechanism whereby this activ ity will spread ver, quick ly from the immediate area if the buildi ng air is not moving ~

An explosion ~uld alert anyone close to it and the inmediate area would be evacuated in a matte r of seconds. Reconnaissance and remedial action would then be carrie d out with supply-air masks.

Failu re* of Iodine RP1Doval Equipment 8.32 As in all of the situat ions in which activ ity is put up the stack , here again there is no hazard inside the plant at all except in the unlik ely case of direc t

  • 20 ~c/sec x 0.1 diluti on factor x O.l frequency 8 l.~ x 107 cc/se~ = 1.3 x 10- µ:/cc The 40-hour MPC for iodine-131 is 9 x 10*9 p,c/cc which is lower than *the above calcu lated conce ntrati on by only about 30 perce nt. Thus, this conce ntratio n could be permi tted for over two days. It is unlike ly that the recyc le would be in- just the right positi on for more than an hour during the day. In any event this conce ntratio n would trip all the build ing air monitors and the incide nt would be dis-covered more readi ly and the dissol ver shut down. *. .

Minor Accidents 8.33 We do not believ e that the accid ents which have been discu ssed in Sectio ns VII and VIII will occur . It .is a good deal more likely , however, that during the course of the opera tion of this plant there will be a number of much more minor occurrances which pose no hazard 3t all to the gener al publi c but which, if they were not handled prope rly, could lead to additi onal exposure of the plant perso nnel. Such

event, alght tp., llluatr1ted bya

a. Spllllng of activity, particularly analytical aamplea or special samples such as waste tank sample.
b. Tracking of spilled activity from on& place to another.
c. Pulling activity into jet steam lines by improper venting.
d. Leaking waste lines in diversion boxes ,
    • Spilling of product solution.

The problem with all of this type of event ls the same. In one way or anothe~ they lead to an increase ln the background radiation which the worker may receive. This is undesirable since in nuclear work one wishes to avoid any unneces.s ary radiation. It is also undesirable since it is important to keep the "operating background" as low as possible in order to leave a cushion with which to carry out the required maintenance work. There are several lines of defense against this sort of problem and they are the same for all of thems

a. First, the plant has been designed to eliminate, insofar. as possible, the necessity for handling even small amounts of activity.
b. Second, the operating rules are designed to eliminate 9very possible exposure.
c.
  • Third, the fixed monitoring system (see Paragraphs 6.66 through 6.76) is designed to detect increases in either background radiation or air concentrations.
d.
  • The fixed monitoring system is backed up by a formal mobile monitoring and survey program (see Section IX).
e. Each employee will wear both meters and film badges. He will be trained to chec~ his own e:q,osure rate frequently and to use portable monitors himself so that he need not rely completely upon Health-Safety Coverage.

the** alnor accidencredibl Thu*, ts should not go undetected. tlone of th*** accidents could y result in exposure to plant personnel ln excess of the limits set forth ln 10 CFR Put 20. .

. 8.34 In- this section we have shown that we are able to operate the NFS plant under all normal conditio ns within the requirements of 10 CFR Part 20 as they pertain to the protect ion of the plant personnel. This includes protect ion froai external radiatio n, inhalat ion, and ingestio n. Both the operati on of the process proper and all the necessary aalnten ance operatio ns are included in this stat~e nt.

a.~ The same aeries of hypothesized major acciden ts that were discussed in Section VII have been considered from the standpoint of the protect ion of the workers in the plant. It i ~~~~9Wn that each of these unlikel y events could be sustaln td without undue risk of exposure to plant personnel.

8.36 Finally the problem of minor acciden ts that could lead to increas es in the background ~adiation received by plant personnel ls considered and the multipl e series of defenses against these *are shown.

needed.

9.39 The perimeter samples are changed weekly and are I

analyzed once as soon as practical after sampling and again four days

' after sampling. The samples are analyzed by counting for one hour in a low background aipha, beta proportional system (see ~ppendix 9.39a). The geometry of this system is 50% for beta and 35% for alpha. The background is about l c/m. The concentration of beta emitters is determined as shown in Appendix 9.39b and the concentration of alpha emitters is determined as shown in Appendix 9.39c. A log is kept of air sample results. These results become part of the permanent record of radiation-contamination conditions in and around the plant.

9.40 Radioiodine activated charcoal filters from the stack and p~rimeter ~tations are analyzed as follows: The filters are gamma .

scanned to dete~ine if there are other gamma emitting isotopes present and in what proportion. Since the radioiodine filter is preceded by a particulate filter, there will normally be no interference from other isotopes.

9.47 A regular schedule of routine surveys will be performed by Health and Safety. The routine survey program is designed to supplement the reports of radiation contamination conditions which are encountered during maintenance and other work, and to insure that all plant areas are surveyed on a regular basis. Each routine survey is described in consider-able detail on the "routine survey" form \See Appendix 9.47) which will serve as a guide for the Heal th and Safety person11el performing the survey.

A list of routine surveys is shown in. Table 9.47. A written record is made of every survP.y performed by Health and Safety personnel. This record which is executed on pre-numbered survey log sheets becomes part of the permanent record of radiation-contamination conditions in and around the plant.

Environmental Survey Program 9.48 The environmental survey program, pre-operational and post-operational is divided into three categories:

1. Atmospheric monitoring including air particulate monitoring;
  • 2. Water monitoring including surface and -ground water 3.

sampling; Earth and biota monitoring including samples of silt, mud, -plankton, fish an.ci shellfish from Buttermilk Creek and Cattaraugus Creek; soil, vegetation and milk samples from the site and surrounding area *and small game from the site.

  • 9.49 The pre-operational progr e~ is divided into two phases; the first phase, started in the spring of 1963, to establish on site gross activity background with a few analyses for specific isotopes and the second phase, starting in the fall .of 1964, to include more analyses for specific isotopes. Phase II will continue into the post-operational period: Both Phases are detailed in Appendix 9.49. A summary of the Environmental Monitoring Program is presented in Tables 9.49a and 9.49b.

-Waste Disposal Control Program--Gaseous Waste 9.50 Gaseous waste control is accomplished by treatment of waste gases be(ore release, continuous monitoring at the point of release and environmental monitoring to determine the effect, if any, of released activity in the environment. Waste gas treatment is discussed in some detail in Section V~, Paragraphs 6.66 to 6.70. Prefilters, air sc: ubbers, silver reactors and high efficiency filters are used to minimize the amount of radioactive gases and particulates released routinely from the plant.

Revision 1. October 26, 1964

Proc;;a,, Miloperattoo 9.97 lllch design, operating information, and experience exists on the chemical processing of spent reactor fuel, particularly on processing by solvent extraction. *The Purex-type of extraction process, which will be used in the NFS plant, is a thoro49hly tested process and one which .is ex-pected to operate without unusual difficulty. Plant operation is predicated upon the "norm" or usual condition where the equipment operates as designed and no *human mistakes are {Jlade. Obviously, such ideal conditions will no~

always exist. This section discusses possible maloperation in various areas of the plant, the results of such rnaloperation, the method of determining c maloperation, and the corrective action to be taken in the case of the particular maloperation. This information is largely presented in tabular form for ease in review and *assimilation. A list of abbreviations used in the discussion is found in Table 9.97.

Mechanical Cttead End} Processing.

9.98 Maloperations that may occur in the head-end processing are mechanical in nature.

  • M>st of the maloperations envisioned involve a failure of a manipulator grapple during the transfer of f~el elem*nts or f baskets and constitute little or no hazard, as such, but rather an incon-venience and time loss during processingr Maloperations in the FRS, PM:,

GPC, and CPC are itemized in table ,.,sa, b, c, and d.

I Dissolution - Feed *Adjustment.

9.99 Dissolution-Feed Adjustment steps Jnder normal condi-tions are discussed in Sections 4.21 through 4.34. The nature of a mal-operation can vary with the f ue-1 be lng processed. For dis cuss ion purposes, the fuels will be divided into (1) ceramic UC>i or Th<?:2 fuels, cylindrical in form,. clad in stainless steel or Zircaloy tubing (as repre-eented by Consolidated-Edison, Yankee, Commonwealth-Edison, and Northern States Power Fuels), (2) uranium-aluminum alloy fuels (MI'R type), and (3) Zr-U alloy* fuels (STR type). Maloperations in dissolving these types of fuels will be fairly representative of difficulties that can be encountered in all types of fuels processed. by NFS.

A summary of dissolution maloperation for these three fuel types, is given in tabl~ 9.99. Contents of this table are discussed in the following paragraphs a Ceramic Fuels, Stainless- or Zirc;aloy-Clad.

  • Yankee, Commonwealth-Edison, and Northern States PaNer fuels are practically identical in processing. These fuels are chopped, loaded into baskets, and the baskets placed in the dissolvers, as described in Section IV. Dissolvent acid of the appropriate strength is added to the dissolvers, the solution heated, and the dissolution of the fuel proceeds . Too low or too high a dissolvent concent~ation or too little or too ~uch dissolvent added to the dissolver are the maloperations most likely to occur. The r~sults of, and corrective actions
  • required by, such a maloperation are given in table 9.99.

  • and the correct ion needed would be obvious in each case *
  • Flow ratios of the organic-aqueous streams (0/A ratio) have direct bearing on waste losses and decontamination factors. Losses from the HA column, as well as thP IA, IO, and IIA columns, will decrease with increasing 0/A ratios. The magnitude of 0/A increase is limited, however, by the increased flow or ratio change possible in the downstream column, or by flooding the column in question. TFor example, the 0/A ratio in the HA column for the Yankee flowsheet is normally about 1.7. If this ratio is decreased by increasing A (or the feed rat~, to approximately 0.80, the waste losses in the HAW stream will start exceeding the economically permissible value of 0.1% of the uranium in the fuel. Likewise, increasing the 0/A ratio (by increasing organic - the HAX stream) by a factor of 2.0 would result in a flooding condition in the column and again high uranium in the HAW and, additionally, organic phase in this stream.

Operating limits on the 0/A ratios will be set on each of the columns in the system as discussed for the HA column above. Operation outside these limits would be considered maloperation and would be the result of human error, failed or *erratic flowmeters, or metering pump.

  • In each of the above, pulse or flow-ratia maloperation, the most probable result is high fissile losses i~ the raffinate stream. Recovery of fissile *material will be discussed under the operation of the rework system. Column maloperations are tabulated in table 9.100.

Maloperati-0ns in the Partition Cycle Feed Pump Pots and 1,,eter .Head Pots are mainly concerned with flow -rates to *and from the column. These are also discussed in table 9.100.-

procedur&s and administrative controls, which are discussed in the chapter on Nuclear Safety. The rework system receives solutions into the Rework Evaporation Feed Tank (70-8) from seven other collection tanks (40-2, 40-8; 40-10, .40-13, 60-3, 70-10, and 130-8). The solutions in these seven tanks have been sampled; hence, they are of known composition. These analyses determine which solutions shall be routed to Tank 70-8. On the basis of these known co, positions and extraction feed requirements, a procedure is followed for reworking 9ach batch. If soluble neutron poison is required, as determined by analysis, it is added from Tank 140-32 in the cold solu-tion area. Acid, or other reagents, could be added from the same tank, if required. Solution in Tank 70-8 is air-sparged and transferred by steam-jet eductors to the R!work Evaporator 70-4; Because of criticality considerations, Evaporator 70-4 is operated on a batch basis only. A

.low-ievel alarm anJ control prevent ,overconcentration in the evaporator.

Condensate from the rework e*:aporator flows to the Low* Level Waste Evaporator feed Tank. This material will be very dilute acid with some activity in it. the bottoms

  • from the rework evaporator are transferred by steam transfer eductor to the Partition Cycle feed Tank (30-1).

Solutions may also be transferred to the Low-Level Waste Accountability and Neutralizer Tank. Various possible maloperations of the Rework Evaporator sy,tem, togeiher with possible *consequences, alarms, indica-tions, and corrective measures,are listed in table 9.107.

Wast& from the parti-tion cycle or from the rework evaporator can be transferred to the High-Level Waste Evaporator Feed ~ank. Solution may be t~ansferred to the
