NUCLEAR REGULATORY COMMISSION'S OPPOSITION TO THE MOTION FOR INJUNCTION PENDING APPEAL i

The Susquehanna Valley Alliance (SVA) has moved this court to enjoin, pending further court action, the Nuclear Regulatory (NRC) f rom approving the processing of radioactively contaminated ' waste water through EPICOR-II, a filtration and ion exchange decontamination -

systec et the Three Mile Island Unit 2 nuclear facility (THI-2)-.

There are four requirements which SVA must meet in order to obtain.a

, preliminary injunction:

(1)

A reasonable likelihood of prevailing on the merits; (2)

Im:ninen t and irreparable harm to themselves unless the injunction is granted; J

(3)

Absence of substantial harm to other interested parties; and (4)

Absence of harm to the public interest.

MD40RANDUM AND ORDER i

Because of the March 28, 1979 accident at the Three 11ile Island Unit 2 i

nuclear power plant-(TMI-2), substantial amounts of radioactively contaminated

]

waste eter have been collected in tanks at the facility.

As the initial step ir, a program to deal with this accumulation, th( Commission's technical staff has recomended that Metropolitan Edisor Company, the licensee for Three Mile Island, j

be permitted to operate an' EPICOR-Il filtration and ion exchange decontamination i

system to decontaminate intermediate-level radioactive este water now held in tanks in the TK]-2 auxiliary and fuel han'dling building.

This recommendation is accompanied by the staff's environmental assessment of the impact of using EPICOR-11 and an analysis of ccoments on the assessment by the public.

The staff has concluded, based on this assessment and analysis, that the proposed use of EPICOR-11 will not significantly affect the environment and therefore that no environ-mental impact statement need be prepared prior to authorizing the licensee to operate EPICOR-II.

The Commission is now called upon to decide whether the i

regard to the proposed use of EPICOR-Il and, if: so, whether the -licensee should j

be. directed -to operate the system.1/

\\

B AC XGROUND l

There are three major volumes of radioactively contaminated waste water' i

i accumulated at Three Mile Island Unit 2. (TH1-2) as a result of the accident in l

Ma rch 28,1979. These include approximately 630,000 gallons contained in the i

lowr levels of the reactor-containment ~ building, 85,000 gallons in the~ reactor I

coolant system in use to remove decay heat.from the reactor core, and about-i 387,000 gallons. stored in tanks in the auxiliary building.

The waste water stored in the auxiliary building has a total radioactivity. concentration less.

l than 40 microcuries/ milliliter and is referred to as intermediate-level waste l

The radioactivity concentrations of wasti water ir, the reactor building l

wa er, and in the primary coolant systems have been measured at greater than 100 pCi/ml

.for some isotopes'.

This waste water is ' referred to as high-level was te water.

l

\\

Principally because of leakage from the primary reactor coolant system,.the l

volume of water in the reactor containment building is increasing'in volume by I

about 430 gallons per day, equivalent to' a level increase of about 2 inches per month.

The present height is about 7-1/2 feet above the basement floor in the l

containment build ng.

Since no paths of Irakage to the outside have been iden-tified, decontamination of this water is not at present an urgent problem.

The l

situation is different with respect to the intermediate-level waste water now 1/

This decision does not address the subject of disposal of the decontam-inated water.

Pursuant to the Commission's Statement of May 25, 1979, i

discharge of THI waste water is not permitted, with certain exceptions set out in the Statement, pending completion of an environmental sssessment dealing with'such discharges.

1 s

i 3

1 stored in the auxiliary building.

The inventory of this water is increasing at' '

the rate of.about 800-1000 gallons per day U Remaining capacity in the aux'il-iary building tanks as;of the end of September 1979 was' about 29,~000 gallons; Thus there is 'a pressing need to ' deal.with the intermediate level waste water.

In addition to the problem of inadequate storage capacity, the retention of l

contaminated water 'in the auxiliary building contributes to the occupational.

exposure of workers at the THI site.

The continued saf e shutdown of Dil-2 'de-l pends upon the use of equipment located in the, auxiliary builping.

Approximately 50 workers per day are currently ' admitted to the auxiliary building to perform necessary decontamination, operations, and consthoction activities. Occupational exposure to these verkers as a group, primarily as a result of radiation from the stored water, everages about 15 man-rem per month.

The licensee has developed a procedure to decontaminate the intermediate-level waste water using the EPICOR-Il filtration and ion exchange system con-structed at Thl-2 following the Ma rch 28, 1979 accident.

Decontamination would

)

be an effective response to the problems identified abcve, since the processed

(

water would not be a source of significant occupational exposure and could be readily stored in unshielded tanks outside the auxiliary building.

Successful operWon of EPICOR-Il will serve to transfer the significant radioactive con-ta;,inants from a mobile forTn (suspension in water) to a fixed fom (held in filter and ion exchange resin r,aterials).

I In : Statement dated May 25, 1979 the Commission directed its technical staff, pursuant to NEPA, to prepare an environmental assessment of the use of U

The dominant source of this increase is leakage from the component evap-orative cooling system, the demineralized water system, and the reactor building cooling system, and from recirculation of water in the tanks prior to sampling. Most of this leakage is non-contaminated water which becomes contaminated while passing through avriliary building floor drains and sumps provided to collect the leakage.

Pursuant to' this Statement, the licensee was not pemiitted to operate 1

l' ment, except for testing with uncontaminated water.

The staff's assessment, "Use of EPICOR-Il at Three Mile Island, Unit 2," NUREG-0591, was issued for public coccent on August 20, 1979.

See 44 Fed. Reo. 48829.

The assessment concluded that the proposed use of EPICOR-Il would not significantly affect the quality of f

j the environment and that accordingly NEPA does not require, preparation of an.

impact statement prior to permitting EPICOR-II to operate.

Some 40 comments were received.

In written analyses of the comments and a and October 10, 1979, oral discussion at open Commission meetings on October the staf f responded to these comments and reaffirmed its conclusion that the

' I environmental effects of operating EPICOR-Il as proposed wuld be insignificant, See revised NUREG-0591, dated October 3,1979.

Tne public comments, the docu-ments submitted to the Commission by' the staff, and transcripts of the October 4 and October 10, 1979 meetings are included in the administrative record and for-the basis for the Commission's decision on tr.is matter.

~

lHFACT OF EPICOR-ll Based on Comission review of the facts and analysis in the staff's environ-mental assessment and written and oral discussion of the comments, the Commission has determined that the proposed operation of EPICOR-Il will not tave a signi-ficant effect on the environment.

Pursuant to 10 CFR 51.7 and Si.50(d) the staff 4

is directed to issue a negative declaration stating that an environmental impact statement for the proposed action will not be prepared.

E With respect to the transcripts of the October 4 and October 10, 1979 l

meetings, the Commission has waived its usual rule that statements at an open meeting are not part of the record of decision of the matters dis-l cussed therein.

10 CFR 9.103.

s 5

In reaching this conclusion the Commission has taken note of comments which

~

a rgue that the. Commission has violated NEPA by. considering 'the impact of EPICOR-II-separately and' apart from the overall impact of a-complete program for decon-q tamination of THI-2.

The Commission does not believe this " illegal segmentation" a rgument is well-founded in trils case.

In meeting NEPA requirements'an agency

- v may focus on the impact of a single action, even when it is arguably a segment of a larger program, when the action in question has independent utility. See e.o_.,

lookout Alliance v. Volpe, 484 F. 2d 11 (8th Cir.1973); Friends of the Earth v, j

Coleman, 513 F.2d 295 (9th Cir. 1975).

The Commission finds that use of EPICOR-l 11 meets this test.II The independent utility of EPICOR-Il is emphasized by the fact that decon-tamination of the intermediate-level water appears by a considerable margin to be the best available response to the impending accumulation of intermediate-level waste water in excess of adeovately shielded storage capacity.

The al ternative ~

1 to decontamination would be to find addiiional storage facilities, but problems 1

with this alternative are severe.

Construction of new tanks Mth the necessary l

shielding would require several nonths, at least, and could not be accomplished l

Al in.this regard, by letter of October 10, 1979, the Council on Environ-mental Quality asked to meet with the Cornission to discuss its concerns about prospective radioactive cleanup operations'at the Three Mile lsland Unit 2 reactor.

Our respective General Counsels and members of their staffs met on October il to discuss these matters, in an exchange of letters with the Commission dated October 15 and October 16 and based on 1

the assurances made in the NRC letter, the Council found that the prompt decontamination of the intermediate-level waste water through the EPICOR-11 system is an operation necessary to control the imediate impacts of an emergency situation (40 CFR 51506.11).

In so doing, however, the Council did not reach those questions concerning the legality of the l

Commission's actions thus far under NEPA.

These letters are part of the j

administrative record on which the Cocmission has reached its decision.

9 a

6 before.the auxiliary building tankage. capacity is exceeded. Other than decon-

]

tamination, there are at present only two. timely alternatives available to pro-f l

ide suitably shielded storage space for the intermediate-level waste water,'once v

the auxiliary building. tanks are filled.

One alternative sculd be to transfer

)

1 7

the wa ter.to tanks at Unit.1.

This action sculd significantly raise the con-tanination, level of piping and tankage in Unit i and extend the scope of the j

. problem of occupational exposure.

The other, even less desirable, alternative would be to transfer the intermediate-level water to the TM!-2 reactor building, mixing it with the higher-radiation-level water presently in the containment, raising the height of that water and in effect increasing by almost 50" the

]

amount of water which must subsequently be decontaminated by systems yet to be l

developed to handle high-level waste water.

Both of these alternatives in effect would enlarge rather than reduce the spread of radioactive contamination and woule involve potentially significant safety cuestions and environmental impacts.

Tne Commission has thus concluded that prompt decontamination of the intermediate-level water by EPICOR-11 is the best response to the situation.

The t

use-of this system will immobilize most of the radioactivity presently dispersed in the intermediate-level water, which requires large storage volumes and in-volves at least some possibility of leakage, by transferring this radioactivity to the compact, more easily stored EPICOR-Il resins, thereby reducing the poten-tial hazard to workers and the public of an excessive accumulation of intermediate-j

]

level waste water.

Decontaminated water shich has been cycled through EPICOR-11 can be readily stored in conventional, unshielded tanks while disposal options are considered without any pressing time constraint. These benefits of EPICOR-II operation, together with the reduction of occupational exposure to wrkers in the r

7 l

auxiliary building, establish the independent utility of the system,EI thereby cor. firming that pursuant to NEPA environmental aspects of EPICOR-II may be evaluated separately from an*overall programmatic analysis of cleanup at ml-2.5/

l l

Another objection to the scope of the environmental assessment made in some of the comments is that the environmental assessment did not consider psycho-logical impacts.

Without deciding whether l' EPA requires the consideration of such impacts, the Commission notes that use of EPICOR-II would provide no objec-tive reason for concern and there is no indication in the ccrraents received that l

the prospect of EP]COR-11 operation, as distinct from release of water, has in fact occasioned public alarm or fear.

Several of the comenters did indicate i

great concern with regard to possible discharge of processed wste ster into the Suscrehanna, but such disposal activities are separate from EPICOR-Il operation and lie outside the scope of the assessment.

The Commission stresse., again that

(

decontamination by EPICOR-11 will not of itself result in any waste water dis-cha ges, and the question whether discharges shoulc later be approved is in no way prejudged by permitting use of EPJCOR-!!.

  • /

Another criterion for permitting segmentation is that the proposed action will not foreclose subsequent alternatives.

Decontamination of the wa ter in the auxiliary building will not foreclose any alternatives with reoard to subsecpent processing or disposal options.

Ra ther, such decontamina-tion may reasonably be viewed as a prerequisite to a variety of alter-native actions sich may subsequently prove necessary and desirable in cleaning up TMI-2.

5I Whether a progrannatic impact statement for the overall cleanup of THI-2 may eventually be required is an issue the Commission need not address at q

the moment.

It seem, clear that no such statement is required at present because 1111-2 cleanup is a project in contemplation and is not yet a formal agency proposal.

The Supreme Court has stated that an agency need not have a final impact statement ready until "the time at Mich it makes a recom-mendation or report on a proposal for federal action." _Kleppe v. Sierra Club, 427 U.S. 390, 406 (1976) (emphasis in the original).

8 With regard to the many technical issues concerning EPICOR-l! that wre raised by the substantive comments, the Connission, as previously acted, has found the staff's responses adequate.

Many of the doubts about EPICOR-Il ex.

pressed by commenters were not relevant t'o the question at issue in the environ-mental assessment, which is whether operating EPICOR-11 will have a significant environmental impact.

Some comments, for example, questioned whether EPICOR-Il will in fact achieve the decontamination levels expected by the staff.

In the Concission's judgment, we expect that EPICOR-Il will be able to remove at least 99% of the radioactive contamination from the intermediate-level waste water the j

sys tem will process.

But that aside, the dettils of the system's performance do not bear on the conclusion that EPICOR-ll does not require an environmental impact statement to justify its use.

For NEPA purposes, once it is determined l

tnat the proposed action will have no significant imoact, no iepact statement is required.

As notec, the Conmission believes the staff's performance expatiations for EPICOR-Il are reasonable, but even if these expectations are not met, addi-tienal decontamination by recycline through EPIC 07.-Il or, if necessary, by other 7/

nethods would in no way be foreclosed.-

One aspect of the proposed EPICOR-11 operation requires further attention he re.

It is the Conmission's view that s' solidification of the EPICOR-11 radio-active waste products (filter and ion-exchance resin materials) prior to offsite M

An alternative decontamination technology frequently mentioned in the comments is the evaporation nethod.

Because an evaporation system is not presently available for use at TM1-2, this technology is not a realistic alternative in the present situation, in view of the need for prompt action.

The Conmission notes that the evaporator method has significant drawbacks, notably the fact that the highly radioactive sludge remaining after evaporation is in liquid fonn and may well be more difficult to i

dispose of than the resins and filters of the EPICOR-Il system.

l

.o

a 9

4 shipment will contribute to improved safety daring transportation and to the ease of final disposal, Accordingly, the Commission concludes that the licensee '

should be directed to construct expeditiously the necessary facilities for solidification and to store EPICOR-Il wastes;at l}il-2 until the resins have been-properly solidified.E There should be no shipment of non-solidified wastes offsite unless necessary to allow waste water decontamination to continue or unless otherwise required' to protect public health and safety.

l U

A staf f menorandum to the Commission, dated October 12, 1979 included in the record of this proceeding, indicates that unavoidable occupational exposure associated with the solidification process can be kept to accept-a ble levels. Although no specific facility designs have been developed f or the solidification operation at T141-2, the staff reviewed three topical reports on systems of this type which show that routine main-tenance and operation activities are expected to result in an occupa-tional dose of less than 10 man-rem per year.

Solidification of resins f rom EPICOR-II, which has not been specifically designed to accommodate solidification, will likely involve design features not previously analyzed by the staff.

Further, resins from EPICOR-Il will be more radioactive than the average from an operating plant.

However, the staf f M

judgment was that solidification of EPICOR-11 resins developed from decontamination of the auxiliary building water would result in occupa-tional exposure levels similar to those of systems previously reviewed if no unusual problems were encountered, and that a best estimate upperbound i

for the operation would be 25 man-rem.

l 10 AT3'11C ENERGY ACT RE0VIREMENTS j;

i t-L We now mov'e to the cuestion whether the Atomic Energy Act authorizes the-Cocnission to direct prompt operation of EPICOR-II.A/ For the reasons stated l

below, we conclude :that it does.

l Our earlier discussion about the accumulation of contaminated water at tlc Unit 2 indicates that public health and safety requires that some action be I

taken to deal with the intermediate-level waste water, and that the timely alter-natives to EP]COR-II operation all present health and safety problems.

Al though no action sich involves the handling of radioactive materials can be found l

1/

One of the ccomenters has argued that construction of E?1COR-Il without a construction permit violated the Atomic Energy Act.

We do not think that construction of EPICOR-11, a minor commit:nent of resources in a $1 billion f acility and unrelated to operation of the reactor itself, is a material alteration of a utili2ation facility within the meaning of our regula-tions and therefore requiring a construction permit.

10 CFR 50.91.

See, Portland General Electric Co. (Trojan Nuclear Plant), LBP-77-70, 6 NRC 1179, 1183 (1977).

Beyond this, the NRC staff has monitored the design and construction of EPICOR-ll from the beginning, so that there are no serious questions about whether the facility is flawed in some manner that might have been detected if a formal permit proceeding had been held.

.Y

1 11 inr.erently free of all risk, the evaluation of EPICOR-Il indicates that no sig-j nificant health and safety (or environmental) impact will likely result from the

]

prcposed operation.

We are thus confronted vith a situation dere some action must be taken to reduce health and safety risks, and an appropriate action to reduce those risks has been identified that itself entails no significant health j

a nd safety haza rds.

Under sections 161b. and i. of the Atomic Energy Act the Corr.ission is empowered to issue such orders affecting activities of licensees as it deems necessary or desirable to protect heal th and to minimize danger to life or property.

Further, every facility license, including the operating license for TH1-2, is expressly subject to further Cornission orders.

10 CFR $ 50.54(h).

An crder to the licensee here to promptly begin the process of decontaminating the int: mediate-level waste water by operating EPICOR !! would be entirely consistent with the purpose of the Act and regulations.

6)

Some of the public commenters have argued in litigation that the Concission h

cannot take such action without first holding an adjudicatory hearing under Sec-k \\ tice 189a. of the Atomic Energy Act to amend the El U it 2 operating license.

I

[

We find section 189a. inapplicable to the type of order contemplated here.

Section 189a. is quite careful in specifying the types of proceedings to which it applies, even going so far as to cite to. specific sections of the Act.

A pro-ceeding for a Comission order under sections 161b. and i. is not one of the proceedings listed in section 189a.

Thus, the plain language of the statute supports the Commission's exercise of authority here. Of course it is possible to argue heie that the order alters the licensee's obligation to the Comission, as such har the effect of amending the license, and consequently that a Section

a 12 i

189a. proceeding for such an amendment should be held.

We think, however, that the entire thrust of the Atomic Energy Act indicates tha t Congress intended the Commission to be able to act with dispatch een in its judgment the public health '

I and safety calls for pronpt action.

Even if for purposes of argument it is assumed that the order constitutes a form of license amendment, the result would i

be,a conflict between the authorization to issue irmediate orders necessary to protect health and safety in sections 161b. and i. and the hearing requirement in section 189a. We have no difficulty resolving that conflict in favor of pro-tection _of the public health and safety especially where, as here, there has already been a fair opportunity fer public participation in the form of written concents.

While w conclude that an order for operation of EPICOR-Il is not subject to section 189a. of the Act, the licensee itself has due process hearing rights I

i under the Constitution cuite apart from section 189a.

Tne law is clear that, given the public health and safety need for prompt EPICOR-Il operation, any due O

process hearing rights can be satisfied by an offer of a prompt hea....g af ter the

. order for EPICOR-Il operation becomes effective.

E.o., Ewino v. Mytincer &

Ca s sel berry, 339 U.S. 594 (1950); Ecwles v. Willinebaun, 321 U.S. 503 (19a4).

And, given that the licensee is free to re' quest a hearing for purposes of challenging the order, we believe that sound administrative policy in these circumstances dictates that other interested persons be given a similar right.

Accordingly, we provide below that the licensee and any other person whose interest may be affected may request a hearing with a view toward lif ting or modifying the order, but that the order shall remain effective pending decision in any hearing that may be requested.

i

13

' One final matter warrants our attention.

Operation of EPICOR-Il will add several ef fluent discharge paths to those presently listed in the THI-2 operating license. As discussed in the staff's environmental evaluation, radionuclides discharges through these additional paths will have no significant impact on, the environment.

Further, the Commission's regulations in 10 CFR Part 50, Appendix A, Criterion (GDC 64), require that the new discharoe paths be monitored.

it has

]

been the staff's practice in developing operating license technical specifica-tions to include in the specifications a listing of discharge paths that require nonitoring under GDC 64 It is not necessary to amend the technical specifications to assure that monitoring will be conducted, given the cicar requirement of GDC 64 and the provision of 10 CFR i 50.54(h) that all facility licenses are conditioned on compliance with all applicable Ccamission regulations.

Nevertheless, we believe that the Commission's inspection and enforcement program will be simplified if the requirements for discharge path monitoring are spelled out in a single legal cocument -- the operating license -- tha t can be reedily referenced by the licensee and Conmission inspectors.

For the same reason there is merit in in-clucing in the operating license the cbligation to operate EPICOR-Il and the ccr.ditions associated with solidification and shipment of the spent resins.

Accordingly, we are proposing to amend the TMI-2 operating license to include these provisions.

In light of our disposition in this regard, and the reasons already discussed as to our authority under Section 161 of the Atomic Energy Act, we need not and do not reach the question whether such a license amendment is required here.

Under section 189a. of the Act, the licensee and other interested. persons may request a hearing on this proposed amendment.

Given the similarity of

issues, hearings requested on this proposed amendment and on the order for EPICOR-Il ~ operation will be consolidated.

ORDER for the reasons stated above, the Commitsion orders as follows:

1.

~ The licensee shall promptly begin the process of decontaminating the.

j intermediate-level waste water from THI-2 by operating EPICOR-il.

Prior to operation, the licensee shall' consult the Director.of NRR for approval of the final operating procedures and design and construction details.

In order to reduce the inherent risk from the contaminated witer most expeditiously ~ and pr.dently, the licensee should to the extent possible process all the water once threugh the EPICOR-1) system.

2.

The licensee shall maintain suitable tankage at El-1 that could be used to store waste water from El-2 at an appropriate state of readiness. should additional storage capacity becone necessary.

3.

The licensee shall not ship spent resins of fsite unless they h3ve been l

solidified, and only-then with the prior approval of the Director of NRR, pro-l viced however, that the licensee may ship non-solidified but dewatered spent resins offsite if it deterTnines, and the Director of NRR concurs, that such ship-mer.. is required to assure contSued operation of EPICOR-Il or otherwise required to protect public health and sifety.

The licensee shall expeditiously construct a' facility for solidification of the spent resins anc shall use such facilities f or resin solidification upon receiving the Director of HRR's concurrence with the d'esign and operating procedures.

Also the tanks in_the chemical cleaning building (CCB) are currently part of the EPICOR-II system which was designed by the licensee to treat the water in the Und 2 auxiliary building. Any use of the tanks in the CCB to store radioactive water would compromise its intended purposes as part of EPICOR-II.

Therefore,' these tanks would preferably only be used 'o' store waste in an emergency situation.

t Thus, at the present time, there is only the surge capacity listed in the Unit 2 auxiliary building (25,136 gallons) which is available to hold the water in the Unit 2 anillary building.

Please state whether it is your opinion that water con-taining hight 1evel radioactive vaste is currently etored on the Three Mile Island Reactor site.

t

14. RESPONSEt Current federal regulations do not define high-level radio-1 active waste in the sense used in this interrogatory. However, water' contained in the reacter building basement and the reactor coolant system is considered to be highly radioactive when compared to levels of radio-i activity normally encountered (i.e., greater than 100 uCi/ml) in operat-ing PWRs. Water in the reactor coolant bleed tanks is considered to conhain intermediate levels of radioactivity (i.e., between i and 100 uC1/al) when compared to operating PWRs.
15. INTERROGATORY:

Please describe where that water is being stored and how it is being monitored.

15. RESPONSE Water in the reactor coolant system (RCS) and the reactor coolant bleed tanks is being monitored by periodic sample collection and analysis.

h.uav.c avAty in the reactor building sump is being non-itored by analytical methods which consider water balance and anal ses t

or radioactive material in the RCS. Although procedures are being developed, there is no method for directly sampling water in the reactor b.. ling sump at this time.

21. INTERROGATORY: Please state to the best of your ability where the--

steam released in the Three Mile Island accident fell.

21. RESPONSE During and following the March 28 incident. radioactive j

^

materials in gaseous effluents were released from the auxiliary and fuel handling building ventilation systems which discharge to the environment through the Unit 2 plant vent. The corresponding dose from these releases to the population in the vicinity of the plant de-pends in part upon the local meteorological conditions, namely wind direction, wind speed, and plume dispersion characteristics, which varied during the period of radioactive release. Thus, there is no single location "where the steam released in the TMI accident fell."

However, throughout the accident period, the known meteorological con-ditions indicate that the NNV, ENE, and SSE sectors were the predominant directions from the plant in which radioactive material released from Unit 2 would be expected to be found. NUREG-0558 sumarises radiation measurements made at various times and locations around the Three Mile Island site. The staff made specific periodic estimates of the location f

e r

and relative concentration of releases throughout the course of the accident. These estimates are referred to, but not specifically pre-sented, in NUREG-0558. NUREG-0558 is provided as Attachment 4 in the response to Interrogatory 23.

22. INTERROGATORY: Please state whether any of this steam fell on the Susquehanna River and whether the addition of radioactivity to the River from this steam has been estimated. If such an estimate haa been made, please provide.

28. RT.SPONSE : The environmental impacts resulting from loss of' coolant i

I accidents have been evaluated in the Final Supplement to the Final Environmental Statement related to the operation of Three Mile Island Nuclear Station Unit 2, NUREG-Oll2, dated December 1976. The specific accident which occurred at TM1 was not evaluated. However, the enviros-mental impact of a more severe accident, namely the loss of coolant accident resulting from a larger diameter pipe break, was evaluated in i

Section 7.2 of NUREC-Oll2. Also, the environmental impact of a similar i

accident, namely the loss of coolant accident resulting f rom a small I

i I

diameter pipe break, was evaluated in Section 7.2 of NOKEG-Oll2.

i The environmental impact of the subsequent cleanup and alternatives to discharge was not evaluated in NUREG-Oll2. However, as indicated in e

the May 25 directive from the Comission to the NRC staff, no cleanup or j

discharge of the water generated as a result of the March 28, 1979 i

i accident may begin until the NRC staff completes certain actions. An environmental assessment of the cleanup of this water and alternatives to discharge into the Susquehanna must be completed and the public nust At this p

be provided with an opportunity to conusent on the assessment.

time, the NRC staff is in the process of preparing the envirordnental i

assessment of the cleanup of the vaste water.

40. INTERROGATORY: Please state the basis on which the dilution factor of the Susquehanna River of 250x vaa developed in the Three Mile Island, Unit Two, Facility Operating License Number DPR-73.
40. RESPONSE: The dilution factor of 250 for Three Mile Island, Unit Two, was developed to determine expected doses from the finfish consump-tion pathway for use in the assessments required by 10 CTR Part 50 The specific estimate of 250 was based upon the dilu-Appendix I tion of plant discharge by the average annual flow rate in the middle channel of the Susquehanna River at the site. The river flow is split at the head of TMI, such that during normal flow conditions, approxi-mately 30% of the average annual discharge of 34,000 cubic feet per second (CFS) is diverted to the middle channel on the west side of the island. The average annual discharge of 34,000 cfs was based on records from the U.S. Geological Survey stream gage at Harrisburg, Pennsylvania.

m

-i.
40. RESPONSEt (Continued)

The average annual plant discharge is expected t'o be 80 cis. Therefore, the average dilution factor townstream of.the discharge was calculated to be 125. It was assumed that an individual fish would be upstream of the discharge point % of the time and downstream of the discharge point % of the time.

The dilution was,therefore, calculated to be 250 for the region where finfish exist (within a one-quarter mile radius of the discharge point).

57. RESPONSEt We are not aware of any method to determine the amount of cell damage in humans caused by low doses of radiation (i.e., about 100 mren). In NUREC-0558 (Attachment 4) the dose to a hypothetical offsite taximum individual was estimated to be less than 100 mrea.

Recently DJ. Joseph Cong of the State University of New York at Buffalo presented a talk on the erythroid effects of radiation of rats in the I roentgen (R) range (Symposium on Biological Effects, Imaging Tech-niques and Dosimetry.of Ionizing Radiation, Bureau of Radiological Health, June 1979). At this symposium Dr. Cong stated that he has detected an increase in the amount of normoblasts for bled rats at doses as low as 50 mR. To the best of our knowledge, this is the lowest level of exposure at which cell damage has been observed in animals. However, we are not aware of any studies that have.shown l
