OPPOSITION OF INTERVENOR LIMERICK ECOLOGY ACTION, INC.

TO " MOTION BY LICENSEE PHILADELPHIA ELECTRIC COMPANY-TO SET SCHEDULE FOR DISCOVERY AND HEARING" Intervenor Limerick Ecology Action, Inc. (" LEA") opposes the extremely abbreviated schedule proposed in the " Motion By Licensee Philadelphia Electric Company. to Set Schedule for Discovery and Hearing" ("PECO Motion") for the reasons set forth below:

I. PECO's Proposed Schedule Is Unreasonable While the schedule proposed by Philadelphia Electric Company

("PECO") accommodates its own interests, it does not afford LEA the minimum time required to prepare its case. It therefore does a

not satisfy the minimum requirements for hearing under the Administrative Procedure Act. and the Atomic Energy Act 1 /; nor does it advance principles o'f justice, fair play, or due process.

1/ See,e.a., Administrative Procedure Act, 5 U.S.C. Section 556(d) ("A party is entitled to present his case or defense by oral or documentary evidence, to submit rebuttal evidence, and to conduct such cross-examination as may be required for a full and true disclosure of the facts".

B908290095 090822 PDR ADOCK 05000352 PDR O

58 3

For these reasons,. the PECO proposed schedule is also inconsistent with the Commission's directive to the Board that the remand proceedings be " expedited to the extent consistent with fairness to the carties". Philadelphia Electric Company (Limerick Generating Station, Units 1 and 2), " Commission Order",

May 5, 1989 (slip op. at 2).2/

PECO proposes a mere thirty days for the review of all information already provided under informal discovery in this case, the preparation of all additional discovery requests, the preparation of all responses to all formal discovery, and the review of all of the additional information provided in formal discovery. It then provides only a ten day period for the submission of testimony (in LEA's case, requiring coordination between counsel in Pennsylvania and experts in California). Such a schedule completely ignores the complexity of the issues, the technical requirements involved in the necessary review of the newly revised three-volume PECO probabilistic risk assessment and i

another separate volume, a " Containment Safety Study", addressing 1

2/PECO has already signaled its intention to involve the licensing board in unfair litigation strategy by seeking an order  ;

demanding an expedited response to the PECO Motion. See, Memorandum and Order (Request for Expedited Answer), August 15, 1989, slip op. at 3 ("The requested action is not supported by good cause, nor is it fair to the parties".)

Limerick's severe accident containment response 3/, and the need for meaningful discovery in parallel with LEA's ongoing review of these risk assessment materials.

In addition, unlike LEA's discussion infra, PECO presents

,. absolutely no specific justification for the schedule it i proposes. It merely recites, in a conclusory way, that it has informally provided information to LEA and the NRC Staff, and that "the material already provided by Licensee would constitute its evidence at hearing". PECO Motion, at 3. No wonder PECO wants a hearing schedule which would make it impossible for LEA to adequately review the material submitted and to conduct a meaningful technical review. Its litigation strategy is patent:

(1) present its own " evidence" on SAMDAs even prior to the hearing to the NRC Staff and to the licensing board (by serving e

3/ We say " newly revised" PRA because this most recent three volume PRA (provided to LEA in the middle of July, 1989) represents a substantial departure from the risk estimates which PECO presented in its 1981 Probabilistic Risk Assessment (internal accident initiators only) and its 1983 Savere Accident Risk Analysis (" SARA") (including " external events") which were reviewed by the parties, reviewed by Brookhaven National Laboratories (see NUREG/CR-3028 " Review of Limerick l Probabilistic Risk Assessment", February 1983) and formed the l core of the basis (with required corrections by Brookhaven and

). NRC staff) for the Staff's environmental assessment of severe

, accidents in the Limerick Final Environmental Statement, NUREG-0974, " Final Environmental Statement related to the operation of  ;

Limerick Generating Station, Units 1 and 2". In addition, the  !

. 3-volume PRA provided to LEA in mid-July 1989 failed to contain any analysis of the containment response to severe accidents.  ;

That analysis was contained in a separate three-inch thick report, " Containment Safety Study (Preliminary Dra f t) " . This document, for inexplicable reasons known only to PECO and its counsel, was not provided with the PRA. That document--

obviously critical in any analysis of containment mitigation j options --

was not provided to LEA until weeks later, July 24, l 1989, less than a month ago. '

-the ASLB with its " evidence" contained in pleadings before the Commission.-itself on the. licensing issues now being resolved.by it), (2) preclude meaningful. opportunity for technical review by LEA, and' (3) stampede to hearing with an absurdly truncated

.- schedule, in hopes of obtaining the concomitant rush to judgment which'such a procedural arrangement implies.

The fact that PECO provided to LEA, some less than a month ago, crucial technical risk assessment documents does ngt meaningfully " reduce [] the amount of formal discovery needed by the parties to prepare for - hearing", as PECO claims. See PECO Motion, at 4.

The PECO documents in fact raise more questions than they

  • . answer. This is because, inter alia, the risk numbers depart so significantly from the earlier [NRC Staff and Brookhaven 4

reviewed] PRA documents. LEA has concluded that it will be necessary to investigate in detail this most recent risk analysis.

As we have noted, PECO. has only recently provided LEA with the " updated" relevant PRA and other risk documents for f submission to its primary consultants, Mr. Steven Sholly and Mr.

. Robert K. Weatherwax4 / who have commenced-preliminary reviews of  ;

i those documents. Mr. Weatherwax has indicated that his review of i the PRA materials will require him to obtain from PECO (cr NUS j Corporation, consultant to PECO) the PRA computer models and 4/ The resumes or statements of qualifications-of Mr. Robert  !

K. Weatherwax and Mr. Steven Sholly are attached hereto as Attachments A and B respectively.

codes in a format which will permit the running of the codes on the computer equipment of his expert consulting firm, Sierra Energy and Risk Assessment, Inc.

Mr. Weatherwax has further concluded that the time required

. to review the new PRA, obtain and run the necessary computer models and codes (assuming prompt responses to our requests for the information), coordinate technical information exchange with LEA's other witness (es), perform the required value-impact analyses,. and prepare testimony is 22 to 24 weeks. See Attachment C.5/ Therefore, in view of the time requirements for technical review of recently supplied documents (upon which PECO intends to fully rely for its current risk estimates, and thus any cost-benefit analysis)6/ LEA requests this Board to establish a

5/ This time estimate is not a " leisurely" schedule by any means; in fact, the estimate is based upon numerous generous assumptions in favor of a tight time schedule (e.g., that the new PRA, Revision 5, dated November 1988, is complete and revisions to it are not planned during the period of analysis, that PECO or its consultant will willingly and rapidly supply in mutually acceptable computer-readable form, the full input data set, complete source code, code in executable form, and full output data sets employed to generate the base case results for the new PRA, and that no major mistakes will be uncovered in a new PRA that will necessitate a substantial redo of that analysis) .

6/ LEA will be required to conduct its own complete review

. of the newly issued PRA and containment safety study because, inter alia, the NRC staff appears to be willing for purposes of this proceeding to accept at face value the PECO newly revised

. risk analyses and containment response study. This is in stark contrasu to its previous practice of obtaining Brookhaven National Laboratory review of PECO's risk analyses, a decision which proved to be amply justified. Unlike the NRC staff, LEA is not willing to accept PECO's estimates at face value. Our skepticism is fully warranted in view of the history of the earlier PECO risk estimates. Brookhaven's review of the PRA resulted in sharp disagreement with PECO over the validity of the risk results, with the Brookhaven review estimates of core damage 5

The Scope of the Severe Accident Risk Reduction -

Measures To Be Litigated In This Proceeding May Be Altered By LEA's Anticipated Filing of

Late-filed Contentions In Accordance With the Memoranda and Orders of this Board and the Commission As the Board will note, the Commission's order of July 7, 1989 indicated for the first time that the litigation in this proceeding would be limited to the "same opportunity to obtain consideration of specific SAMDAs as it would have had if its SAMDA contention had been fully litigated before the licensing Board when it was submitted. If LEA now wishc to have other SAMDAs considered, it can do so by satisfying the requirements governing late-filed contentions". Philadelphia Electric Co.

(Limerick Generating Station, Units 1 and 2), Memorandum and Order of July 7, 1989, CLI-89-10, slip op, at 3-4, n.1. This than those proposed by PECO. See, frequency and other measures of risk and Table 3 from NUREG-1068, e.g., Attachment D, Figure 1 Probabilistic Risk " Review Insights on the Assessment for the Limerick Station", August 1984.

staff review and preparation In addition, in the midst of Generating of the Limerick the NRC the NRC staff by letter of March 13, FES, PECO advised errors in the 1983 SARA consequence 1984 that it Such analysis. had discovered a history affords LEA numbers to little basis for sufficient confidence in PECO's blindly accept them for purposes of this adjudicatory proceeding.

never 7/The Board the past requested any should note delay in the that this counsel on LEA commencement 's behalf of any hearing in request a of this now eight-year old proceeding, nor did he ever board hearing because of schedule which nor undue delay was denied by the licensing recollection) any other reason. (to the best of his 6

t______---- --

I Board echoed that conclusion in'its decision' limiting the scope of the litigation to certain specific SAMDAs, and rejecting various low-cost SAMDAs which were set forth in' LEA's submission-

^

" List -of Primary Candidates for Severe Accident Mitigation". It

. noted that other SAMDAs would have-to be presented as late-filed contentions. See, e.g., Memorandum and Order, LBP-89-19 (July 18, 1989), slip op. at 13,17.

'In fairness to the Board and to the other parties -- in. view of its implications for scheduling in this matter -- LEA wishes to provide advance notification to the Board and parties that it is LEA's intention to file as soon as practicable a motion with' this Board to accept as late-filed contentions " the remaining elements of the risk reduction package presented by LEA as its 4

" List of Primary Candidates for Severe Accident Mitigation".8/

LEA's counsel's preoccupation with other filings in this matter following this Board's July 18, 1989 Memorandum and Order denying admission of various elements of LEA's risk reduction package--

l-8/ This list was submitted to the parties and to the Board at the first special prehearing conference in this matter on June 6, 1989. The 3ist was also submitted as part of the "Mamorandum of Limerick Ecology Action, Inc. Pursuant to Prehearing

. Conference Order of Atomic Safety and Licensing Board of June 9, 1989". At that time, LEA believed that its proposed severe accident risk reduction measures vere within the scope of its contention DES-5. LEA further believed that DES-5 was admitted into the proceeding as a result of the remand of the United States Court of Appeals for the Third Circuit in Limerick Ecoloav Action,Inc. v. U.S. Nuclear Reculatory Commission, 869 F. 2d 719 (3d Cir. 1989). While LEA still believes its position to be correct, it is apparent that the Commission disagrees; LEA

- therefore has no choice except to present to the Board a motion for admission of its other severe accident risk reduction measures as late-filed contentions.

has precluded completion'of such a motion to date. However, preparation of the required expert affidavit (s) to support such a motion is nearing.

completion, and LEA expects to . file its motion within the next l

two weeks. Therefore, LEA believes that the fundamental assumptions concerning the scope of the proceeding which underlay PECO's proposed schedule are incorrect.

III. LEA's Proposed Schedule Is Realistic and Properly Accounts for the Complexity of the Issues and the Time Required for Adequate Technical Review and Analysis I

As we indicated above, LEA's experts have concluded that to properly review and analyze the critical risk assessment j documents which will be at the center of the' matters in I

controversy in this case will require a period of 22 to 24 weeks. j The issues in this proceeding travel far beyond simple issues of compliance with. specific regulatory provisions in Part 50.

Instead, they~are questions of first impression in NRC licensing hearings. Never before have such severe accident risk mitigation ]

issues been litigated in NRC licensing hearings, and the j I

technical issues relating to risk assessment and wevere accident  ;

-mitigation based on prcbal;>ilistic risk assessment are relatively j l

new.  ;

To est'iblish a schedulce which does not afford sufficient ]

time to conduct an adequate technical review of the fundamental i

risk assessment documents in this case would deprive LEA of a meaningful opportunity to be heard. Based upon expert best 8

E h estimates of the time requirements to conduct an adequate technical review, LEA proposes the following schedule:

Filing of formal discovery requests Commence upon issuance of order Completion of discovery (including 20 weeks thereafter completion of responses to dis-covery requests as provided by NRC rules of practice)

Submission of testimony 4 weeks thereafter Motions to strike, etc. 10 days thereafter Responses to motions to strike 7 days thereafter Commencement of hearing 10 days thereafter

. IV. Conclusion For all the reasons set forth above, LEA requests that the

~

Board deny the PECO Motion, and to establish a reasonable schedule in accordance with the schedule set forth above.

uncertainties in the values of various input parameters such as hardware failure data, human error data, frequency of accident initiators (especially loss of offsite power), large and medium LOCAs, fires and seismic events. These sources of uncertainties also exist in the Reactor Safety Study. Some of these sources of uncertainties are still dominant sources because of (1) no data on large LOCAs, (2) relatively sparse data base on severe earthquakes in the eastern United States, and (3) inadequacies in quantifying certain human errors during accident scenarios. There is also large uncertainty attributed to varying degrees of systems success / failure modeling assumptions, complete-ness, statistical and arithmetic errors. The impact on the frequency of core damage from this kind of uncertainty is believed to be within range of uncer-O tainties that have been quantified for Limerick.

Both the applicant and BNL have performed sensitivity analyses and have identified potential sources of uncertainty and treated them using the appli-cable state-of-the-art methodologies. Figure 1 shows a perspective on the range of uncertainty associated with the core damage frequency, as estimated by the applicant and BNL. Note that BNL's estimate of the fifth to the 95th percentile probability range for the frequency of core damage from transients and LOCAs spans almost 2 orders of magnitude (7E-6 to 3E-4 per reactor year) and is greater than the corresponding estimate by PECO.

To provide a perspective on the range of uncertainties on various contributors to the core damage frequency, the staff has provided Table 4 which gives esti-mates of uncertainty and the mean values of the class of accident sequences Limerick RER 2-10
