SUBJECT:
SUMMARY
OF MEETING WITH SEISMIC QUALIFICATION UTILITY GROUP (SQUG)CONCERNINGSEISMICQUALIFICATIONOFEQUIPMENTUSIA-46 L
On February 2, 1990, the NRC staff met with representatives of SQUG concerning the current status of the SQUG 3rogram for resolution of USI A-46 and to reach egreement on actions to bring tie program to closure. The main points discussed and agreements reached are summarized as follows:
- 1.
Status of SOUG program and SQUG's position on open issues.
Mr. N. P. Smith, SQUG Chairman, presented a sumary of the status of the
['
SQUG program and SQUG's position on open issues affecting completion of the program. The information presented by Mr. Smith is given in i.
In sumary, Mr. Smith indicated that SQUG has been actively proceeding'with development of technical criteria for resolution of USI L.
A-46, despite the lack of formal acceptance of certain elements of the progran by the NRC in the form of Supplement 1 to their generic Safety E
EvaluationReport(SER). He indicated that SQUG is reluctant to expend L
substantial additional resources in the training program detelopment.and L
implementation without resolution of-(1) the legal challenge to use of GenericEquipmentRuggednessSpectra(GERS)and(2)openlicensingissues, b
Dr. Richardson and Mr. Marsh acknowledged that they understood the SQUG' I-position. They also indicated they wish to make clear the NRC's position on.USI A-46, which is to implement resolution of USI A-46 as soon as possible,' independent of future programs which may impact USI A-46 such astheIndividualPlantExaminationforExternalEvents(IPEEE).
However, they indicated that utilities would be prudent to coordinate any data gathering needed for IPEEE with the USI A-46 walkdowns. They indicated that necessary guidance for the IPEEE data gathering will be
@/0g S
issued by the NRC in time to support this approach.

Legal challenge by Westinghouse to GERS.
Westinghouse transmitted a letter to the NRC in late 1988 which challenges the use of the SQUG/EPRI Generic Equipment Ruggedness Spectra (GERS) by the NRC. The NRC has not responded officially to the Westinghouse legal i
challenge. The NRC staff representatives indicated that they are presently preparing a negative consent position paper on this issue which will be submitted to the NRC Comissioners in the next few weeks. This position paper is expected to state that the NRC staff does not agree with the Westinghouse challenge of the use of the GERS by the NRC. The negative consent position paper will indicate that if the Comissioners do not disagree, the staff will proceed and allow the use of GERS for equipment verification, Dr. Richardson suggested that the SOUG utilities may wish to explore this matter further with Westinghouse in parallel with the NRC's disposition process. The timing for resolution of this issue is i
j unclear, >ut it is unlikely to be resolved in less than two months.
SQUG representatives advised that the use of the EPRI/SOUG-developed GERS is an essential element of the SQUG generic program, particularly for equipment not included in the experience data base and for equipment L
installed at high elevations in nuclear plants. They also noted that GERS and similar published data mey be needed for planned future seismic evaluations such as the IPEEE.
l 3.
Licensing Issues The ettendees discussed the licensing issues which are considered signifi-cant by SQ'JG for which formal NRC acceptance has not been received. The nainissuesare(1)whethertheUSIA-46rulescanbeusedforseismic verification of new and replacement equipment in A-46 plants, and (2) whether the plant's licensing basis for seismic qualification of ecuipment can be changed to be consistent with the use of A-46 rules.
l l
tir. Schmidt (P.PR) sumarized the NRC's position on the use of USI A-46 1
rules for new and replacement equipment as presented officially in NRC Generic Letter 87-02 and as given to SQUG by the NRC staff (Mr. Marsh) during several previous SQUG/NRC meetings. This infornetion is summarized in Enclosure 2.
The NRC staff acknowledged the correctness of SQUG's presentation of the NRC's post position on this subject and indicated that the NRC's positions l
on these licensing issues are currently being reevaluated by the NRC staff.
They stated that the NRC positions on ti,ese issues will be promulgated officially in the NRC's SER supplement which should be issued within 60 days. Based on the discussions at this meeting, it was agreed that the HRC SER supplement need not address the SOUG technical criteria since the i -
technical information in Revision 1 of the GIP has been significantly 1-revised.
E S
, March 13,1990 1
SQUG representatives expressed concern that the NRC has found it necessary to reevaluate their long-standing position on the application of USI A-46 rules to future equipment applications.
SQUG representatives noted that a change in the NRC position would likely result in reevaluation of utility plans for resolution of USI A-46, 4.
Technical Issues
[
SQUG representatives advised that essentially all of the open technical issues have been resolved between SQUG, SSRAP and the NRC staff, leaving only two issues on which SQUG and the NRC have chosen to disagree. These two issues are:
o The use of 3 X Dead Weight as a screening method for evaluation of all calde trays; and The use of 7 versus 6 as the generic amplification factor for relays o
installed in switchgear.
The letter issue on use of an amplification factor of six or seven for switchgear is not expected to have a significant impact on the seismic verificction of switchgear.
In the case of the 3 X Dead Height screening criteria for cable trays, SQUG proposed a compromise approach for resolu-tion cf this issue. The compromise is that SQUG could eccept the use of 3 X Dead Weight as_a screening criteria for all cable trays with the under-standing that the alternative lateral load c. heck, described in the E0E cable tray report, would be an acceptable approach for resolving outliers which do not meet this 3 X Dead Weight vertical capacity check. This compronise would retain the cencept that the screening criteria would flag those cable trays which are not consistent with the earthquake experience data base, yet provide reasonable, fWst principlet approach to resolve outliers which would result from this screening check. The NRC staff indicated that the use of alternative lateral load check as an approach for resolvir.g outliers will be reviewed on a case-by-case basis.
5.
Future Course of Action The tiRC management representatives summarized actions which are underway by the NRC staff to resolve the open legal and licensing issues. They are proceeding to 3repare a position paper for submission to the Commissioners on the legal c,allenge to the use of GERS. This position paper will have to be reviewed by appropriate individuals in the NRC staff before submittal to the Commission.
In parallel, the NRC staff will prepare and issue an SER supplement covering t!.e open licensing issues discussed at this meeting.
This SER is projected to be issued within about 60 days.
SQUG representatives indicated that based on the discussions at this meeting, SOUG cannot proceed to cormiit significant resources until the open issues are resolved. This will likely mean that development of the SQUG training program
