SUMMARY

OF MEETING WITH COMMONWEALTH EDISON TO DISCUSS THE INDIVIDUAL PLANT EXAMINATION FOR EXTERNAL EVENTS PROGRAM On October 15, 1992,.the NRC staff (the staff) met with Commonwealth Edison Company (the CECo, licensee) to discuss CECo's Individual Plant Examination for External Events (IPEEE) program and schedule. A list of attendees is provided as Enclosure 1.

A copy of CECo's slide presentation is provided as.

The meeting had been requested by the licensee to provide the staff with an overview *understanding of CECo's IPEEE program and to explain the reasons for the extended schedule requested by the licensee for completing their program.

In their presentation, CECo emphasized the necessity to complete their Individual Plant Examinations (IPE's) prior to commencing their work on the IPEEE.

They also indicated that the IPE/IPEEE process was interrelated with their work for the seismic qualification issue (USI A-46).

In addition, CECo's resources for doing IPE/IPEEE work are limited.

For all these reasons, CECo stated that they need the extended schedule shown in Enclosure 2 to complete their I PEEE work.. At the staff's request, the 1 i censee committed to submitting an integrated schedule showing their milestones for IPE, IPEEE, and USI A-46.

This schedule should help the staff to better understand the schedular difficulties that CECo is experiencing. After examining the integrated schedule, the staff will notify the licensee as to the acceptability of their schedule.

The staff raised one concern which will be pursued in a separate meeting.

The licensee is establishing their own screening criteria for determining a~eas for performing focused analyses.

The staff indicated an interest in this screening criteria since CECo does not want to use the criteria already approved by ~he staff. The licensee, however, has not yet determined the criteria and was unable to provide any details at this meeting.

The licensee

. expects to have this criteria established in a preliminary form by

RELATIONSHIP TO NUREG 1407 OBJECTIVES

1. UNDERSTAND SEVERE ACCIDENT BEHAVIOR; THE EDISON PROGRAM IS CLOSELY TIED TO THE BASIC EDISON IPE PROGRAM WHICH*-

. AFFORDS UNPARALLELED INSIGHTS INTO SEVERE ACCIDENT BEHAVIOR OF EDISON PLANTS; THE EDISON IPEEE: WILL RELATE

  • PLANT BEHAVIOR RESULTING FROM EXTERNAL INITIATORS TO THAT BODY OF.

KNOWLEDGE AND WILL, AS AND IF* NECESSARY, SUPPLEMENT THAT KNOWLEDGE WITH NEW PLANT ANALYSES.

2. UNDERSTAND THE MOST LIKELY SEVERE ACCIDENT SEQUENCES;
  • 1 THE EDISON IPEEE WILL IDENTIFY THE LIKELY PROGRESSION OF SEVERE ACCIDENTS.

RESULTING FROM EXTERNAL INITIATORS BY RELATING THE EVENTS TO BASIC IPE SEQUENCES OR, AS AND IF NECESSARY, BY EXAMINING NEW SEQUENCES.

---=

-~-

.~

3. OBTAIN A* QUALITATIVE UNDERSTANDING OF THE LIKELIHOOD OF CORE DAMAGE AND FISSION PRODUCT RELEASES; THE EDISON IPEEE WILL OBTAIN SUCH AN UNDERSTANDING BY ASSESSING THE RELATIVE LIKELIHOOD OF SEQUENCES.

IN A QUALITATIVE MANNER.

4. TAKE, IF NECESSARY, APPROPRIATE ACTION TO ENHANCE PLANT CAPABILITIES IN THE AREA OF SEVERE ACCIDENT RESPONSE; THE EDISON IPEEE WILL BE CONDUCTED WITH A GREAT DEAL OF ATTENTION TO SEARCHING FOR INSIGHTS AND POTENTIAL ENHANCE-MENTS. THE PHILOSOPHY MOTIVATING THE BASIC IPE WILL BE CONTINUED.

IF NOT WHOLLY, IN THE SCREENING ANALYSES. SELECTED SCC'S-MAY BE EXCLUDED FROM FURTHER FIRE AND SEISMIC WORK BASED ON THE SCREENING ANALYSES.

WALKDOWNS

1. SEISMIC WALKDOWNS FOR A-46 PLANTS IN CONJUNCTION WITH SQUG EFFORTS
2. NON A-46 PLANTS WILL BE DONE USING SIMILAR CRITERIA.
3. ANTICIPATE TWO TYPES OF ISSUES:
  • OBVIOUS PROBLEMS SUCH AS MISSING SUPPORT COMPONENTS
  • MORE SUBTLE PROBLEMS FOUND BY SEISMIC EXPERTS SUCH AS POTENTIAL TANK FAILURES VIA BUCKLING.
4. FIRE WALKDOWNS BY FIRE AND PRA ENGINEERS. SIMILAR DIVISION OF ISSUES TO THAT EXPECTED FOR SEISMIC~
5. PREMIUM ON CAREFUL ORGANIZATION OF WORK, USE OF EXPERTS, TRAINING OF PERSONNEL, DEVELOPMENT OF GUIDELINES.

AND CAREFUL DOCUMENTATION OF EFFORT

  • -FOCUSED STUDY
1. TOPICS DERIVED FROM SCEENING ANALYSES AND WALKDOWNS.
2. TECHNIQUES INCLUDE FOCUSED PAA, SPECIFIC DETERMINISTIC ANALYSES OR A COMBINATION OF THE TWO.
3. PAA WORK WOULD INCLUDE THE SPECIFIC SEISMIC OR FIRE FAILURES OF INTEREST
  • EVALUATED IN CONJUNCTION WITH RANDOM FAILURES IN THE FRAMEWORK OF THE BASIC IPE.
4. BOTH PRIMARY EFFECTS (FIRE OR SEISMIC INDUCED LOSS OF SSC) AND SECONDARY EFFECTS (FLOOD FROM FIRE PROTECTION SYSTEM OR RUPTURED TANK) WILL BE CONSIDERED AS APPROPRIATE IN PRA WORK.
5. EMPHASIS WILL BE PLACED ON CAREFUL DOCUMENTATION AND BENCH MARKING OF RESULTS AND RATIONALE FOR RESULTS.
