MEMORANDUM AND ORDER

'JPCA's Motion Concerning Anticipated Transients Without Scram On May 7, 1975, during a hearing session in the above-captioned proceeding, Intervenor Minnesota Pallution Control A v.e nc '. (MPCA) filed with the presiding Atomic Safety and Licensing Board (Roard) and parties a document entitled m,'n iss ion 01 Additional Contentions." The contentions caiwd therein related to the Applicant's analysis of the unsequences of anticipated plant transients in the event a postulated ! 't i lu re to scram. At the request of the o: r< 'dPCA i iied , reframed contention in the form of a r w l on o. Revised Additional Contention" (hereafter, contention C.1) on May 14, 1975. In response to the coquests of the parties on May 15, 1975 (Tr. 1817), the

Applicant) and the Nucicar Regulatory Commission Staff (the Stall) each filed a response to MPCA's submission of the additional contention. In addition MPCA filed a memo-1975, .

randum of law dated June 3, ,

By way of background, it is to be noted that one'of MpCA's contentions in this-proceeding (Contention II-33) was admitted as a challenge to the appropriateness of the st all assertions of low probability of Class 9 accidents Pur-forth in the Final Environmental Statement.

as set suant to an agreement between counsel for the Stafi.and MPCA',

t he S taf L's prepared testimony on Contention II-33. was two kinds of Class 9 accidents, limited'to consideration of pressure vessel failure and anticipate'd transients without scram (ATWS). The Staff's testimony on ATWS was considered during the ~

1975. .

evidentiary hearing in-this proceeding on May.6 and 7, As noted above, MPCA's motion to introduce additional ATWS.

-contentions was presented during.the course of the eviden-tiary hearing on May 7, 1975.

ATwS. Therefore, the plant should be modified so as.

to reduce the probability of such incidents'.

The basis for the contention is stated to be' the following:

(1) " Supplemental Testimony of Nuclear Regulatory Commis=sion Staff on Contention II-33," particularly pp. 3 and 92.

(2) " Technical Report or Anticipated Transients Without Sc ram f or Water-Cooled Reactors ," WASil-1270, which is referenced in the Supplemental Testimony and was served.

on the parties along with the Supplemental Testimony.

(3) Cross-examination of Starf witnesses (Tr, at 104'3-1049).

.la m :_<e r of Nuclear Support Services, Northern States power Company to A. Giambusso, Direc tor, : Division of . Reactor Licensing, U.S. Nuclear Regulatory Commission.

In its-response, Applicant requests that the Board reject Contention C.1 because it is overly vague as well-as being premature. With regard to the latter,.' Applicant argues that WAsil-1270 makes i t clear that for'the-Monticello

The Staf f ~ supports the admission of MPCA's Contention C. 1 as an issue in controversy in this proceeding and  ;

urges the Board to find that MPCA has shown good cause for the nontimely filing of ' the contention.

The sufficiency of Contention C.1 must be measured against the requirements of 10 CFR 52.714 of the Commis '

sion's Rules of Practice. In accordance with $2.714(a),.the' contention must be stated with reasonable specificity and with some basis provided. Northern States Power Company (Prairie Island Nuclear Generating Plant, Units.1 and 2)

ALA3-107, RAI-73-3 at 188, 194 (March 29, 1973). If the t iling is nontimely,tne petitioner must also-make a substan-ttal showing of good cause.for failure to file-on time, he believe that Contention C.1 is clearly stated with reasonable specificity and with sufficient basis provided.

In order to determine whether MpCA has shown good cause for the late t iling of the revised contention, it is necessary to consider the history of the ATWS matter as it relates to the Monticello plant.

In September, 1973 the Sta r f issued a " Technical Report on Antic

  • pated Transients Without Scram (ATWS) for Water-Cooled power Reactors", WASH-1270. This Report established three categories (A, B, and C) of nuclear power reactors and t o A I'WS preneribed " programs of implementation" with respect considerations for each category.

(Id. Appendix A), Monticello ialls within Category C, applicable to plants for which neither the Connission's Saiety Evaluation Report nor the Advisory s amistce on Reactor Saleguard's Report at the construction l'or pernit stage identified ATWS as a matter under review, is t e e. o r s, C plants the Staff required submission by October 1,

.1 analyses 01 AThS consequences and reviews of reactor u n u i d bv. u system design. Thereafter, the Statf would determine t ni wd tor plant changes on "an individual case basis".

6 Pursuant to hASil-1270, the Applicant submitted on October 1, 1974, a review of the design of Monticello's reactor protection system (NEDO-20G35, " Evaluation Report--

Common Mode Failure Vulnerability of Reactor Protection System Instrumentation for the Monticello Nuclear Generat-ing Station") and was granted an extension until April 1, _

On April 1, 1975 to file its analysis of ATWS consequences.

1975. the Applicant filed this analysis in a document entitled " Anticipated Transients Without Scram Study for the Monticello Nuclear Generating Plant" (NEDO-20846).

MpCA states that its revised contention is based upon the Applicant's April 1, 1975 submittal on ATWS consequences (including the covering le tter thereto) and the testimony of Start witnesses at the recently completed hearing session.

In NEDO-20846 the Applicant's vendor (General Electric) clearly states that "... if a serious ATWS event is postu-lated, the conditions could exceed the General Electric guidelines without plant changes". (p 3) For that reason, G E. continues,

" ... minimal plant modifications are considered in this analysis". G.E. then proceeds to enumer-ate the tollowing plant modifications: recirculation pump trip. feedwater pump trip, and modification of the Automatic Depressurization System. The Staff concluded after review-for ing NEDO-20846 that "... the analysis submitted was not It was for a hypo-the tacility presently constituted.

thetical facility."- '(Tr. 1054) The report does not,-there-fore.-comply with the-requirements: set forth in WASil-1270,. - _ -

i.c., an analysis.of ATWS consequences based-on existing-Monticello configuration. (Appendix A, particularly-pp. 89-90)

A further conflict between the Staff and Applicant regarding ATWS was revealed in the April 1, 1975 submittal' and the Staff's' response thereto at the recent hearing.

The Applicant, despite its recognition that plant changes-will be necessary to accommodate serious ATWS events, concludes in its covering letter (p. 2) that "... we do not believe backfitting of Monticello is presently warranted."-

Responding-to that conclusion a Staff witness stated that

.. the letter does not' agree with the prescnt Regulatory-Staff position'that backfitting is required for'the Mon'ticello facility." (Tr. 1143)

I( is apparent, therefore,-that-MpCA-could not have-known the Applicant's position on whether backfitting is required until it received, at theLsame time as the-Staff, the April 1, 1975 report. Nor could MpCA_have known the-S4att's position on backfitting until it heard the testimony -

of t_he - St a f 1 at.the-recent hearing session.

Section 2.714 of-10 CFR establishes a standard for admission of nontimely filings. 'That standard requires a ,

petitioner'to make "a substantial showing of good cause" _

to justif y the lateness of his/her actions.- Four factors are set out, to which the Board-must give special consid-eration. They are:

(1) The availability of other means whereby t he pet it ioner's interest will be protected.

(2) The extent to which the petitioner's participation may reasonably be expected to assist in developing a sound record.

(3)_ The extent to which petitioner's. interest will_be represented by existing parties.

(4) The extent to which the petitioner's participation will broaden the issues.or delay the proceeding.

While it is true that WASil-1270 his been available for

s. ome one and one-half years, its application to this pro-ceeding and to this-plant was finally established only in the Staff's testimony on MPCA Contention II-33, served on the parties in late February, 1975. Further, it_was'not s

until the receipt _of the Applicant's April.1,-1975 letter r

transmitting NEDO-20846, that.MPCA became aware that'the-Applicant's position-on this issue;was:in such fundamental conflict with that of_the. Staff. --Until that. time,-MPCA-might- have determinedLthat the Applicant and the Staff could come to agreement as to the appropriate retrofitifor.

9 Montleello, thereby negating the necessity for the Board to consider this matter. Finally, it was not until MPCA's cross-examination of Staff witnesses during the recent evidentiary session in this proceeding, that the conflict betveen the Applicant and the Staff became direct and obvious, and therefore became an issue to which MPCA coald _

legitimately and appropriately respond.

In view of the above, the question of tardinrss does not arise MPCA has act ed as expeditiously r ; possible in an el f ort to bring the issue before the Board as soon as its scope and details became clear to MPCA.

An examination of the factors cited in 10 CFR 2.714 s hov s that MpCA's contention C.1 should be admitted as an issue in this proceeding.

There are no other means by which the safety of the _

'!onticello plant in the event of an ATWS and the extent of tLe consettuences of such an event can be considered Iully a; . putil i cl y before an impartial tribunal such as this Atomic Safety and 1.icensing Board. With regard to whether

'1pC A 's

, participation on this issue may ascist in develop-ing a sound record, had MPCA not raised this issue, there would be no record at all. Similarly, one cannot cc .c . _ue that as to MPCA's interest in the matter of ATWS ovents and

~ . . - . - - - - . - - . . - . - - .. . . - - -- -

k 10 their consequences can be adequately. represented by

" existing parties." While there is an obvious confli.3t- .

between the Applicant and the Staff-on thistissue, if MPCA's contention is not admitted, there will be.consid-eration of this' issue before the Board, but no party will represent MPCA's position.

Tne Appeal Board has provided poine guidance as to-the extent to which delay in the proceeding should' preclude consideration of new issues. In considering a motion to reopen the record, the Appeal Board in the Matter of Vermont Yankee Nuclear Power Corporation'(Vermont Yankee Nuclear Power Station), Docket No. 50-271, ALAB-124, RA I - 7 3- 5 ~, 358 at 365, said:

In this same vein, the applicant has suggested that-the effect-of granting the motion to. reopen would be to permit intervenors to seize upon, as a justification for reopening a hearing, every letter which the staff,-in the exercise-of

-its continuing reguintory responsibility, sends to an applicant. Thus, according--to the applicant,.an intervenor would be able to prevent indefinitely the termination of the proceeding and the rendition of an initial decision authorizing the issuance of an operating-license.

=1 We cannot accept the applicant's un9tated premise that the desirability of-completing the l

-hearing outweighs the need to resolve potentially se ri ous safety matters. .This is so even_though the stari believes that the matters . raised by - a let t er do not. warrant consideration -in the-- hearing but instead can be handled by the staff outside ,

the hearing process. The intervenors have every right, in presenting contentions for consideration, to rely.upon consequential safety matters brought to light by the staff's technical experts.

In short,-delay in the issuance of an operating license at t ribut able to an intervenor's ability to

-present to a licensing board legitimate contentions based on serious safety problems uncovered by the stall would establish not that the licensing system ,

is beinn frustrated, but that it is working properly.

Any delay in such a situation would be fairly attrib--

utable not to the intervenors but to'the non-readiness of the facility I'or operation. Delay in the issuance ,

of the licetse is entirely appropriate -- indeed, mandated -- in that circumstance.

(Emphasis added )

The iacts giving rise to this decision are closely-l analogous to the extant situation and the decision should br dispositive of any argument based on delay. As-in the Wrmont Yankee' decision, the intervenor, here MpCA,_

l has raised aefore the Board a serious safety question.

l_

l l Indeed. an argument based on delay is even weaker in this procc.' ding since the record in this proceeding has not been c l ose d , so any inconvenience or prejudice attendant to admission of the contention is surely less than it would -

l- have been in the Vermont Yankee setting.

1 12 More general guidance as to the standard which the Board must use has'also been provided by the-Commission.

Its order of September 29, 1972, in Matter of Indiana and-Michigan Electric Company (Donald C, Cook Nuclear Plant, Units 1 and 2) has long provided a precedent for Licensing Boards in considering new issues. _

The. Commission said; we note our longstanding - practice of permit ting-amendments to petitions to_ intervene.for good cause shown. Unless special considerations-dictate otherwise in specific circumstances, new information appearing in previously unavail-able documents would generally constitute good -

cause for amendment, assuming of-course that the request to amend is expeditiously presented and is otherwise proper. Such determinations rest _in-the sound discretion of the Licensing Board.

(Emphasis added.)

As noted earlier, MpCA's Contention C.1 is_. based on documents and information available only shortly befor'e-tae motion to add the contention.was made.- Therefore, according to the Commission's standard, MPCA has-made a

. tully satisfactory showing of " good cause" for11ts-filing-of Con ten tion C.1 at this point in the. proceeding. Because-the issue raises _a serious safety-question, any possible-r

- delay in the issuance of Monticello's full term operating license due to admission of this contention is entirely-

~

appropriate--- 'ndeed, i mandated. Accordingly, MPCA's motion-is granted ~ and Contention C.1 is admitted as an issue in-t his proceeding .

l MpCA's contentions were directed at-quantities'-of radioactive. -

ing. Oral arguments were heard on two occasions during the recently concluded session of the hearing, 'Counse1~for Applicant argued that with the adoption-of Appendix I, the Interrenor's contentions' dealing with "as low as practicable" .
