FEB 111981 Docket No. 50-382 APPLICANT: Louisiana Power & Light Company FACILITY:
Waterford Steam Electric Station, Unit No. 3
SUBJECT:
SUMMARY
OF MEETING ON LOCA ASYMMETRIC LOAD ANALYSIS On January 22, 1981, members of the NRC staff met with the applicant and their consultants to discuss the above subject. Attendees are listed in the enclosure.
Summary The applicant's analysis of LOCA asymmetric loads is plant specific for fuel, RPV internals,and CEDM's and the balance of the review references the CE generic report and the St. Lucie report. The staff has some difficulty with this because neither has had staff approval. The applicant's consultant i
Ebasco who is also involved with the CE generic plant analysis will attempt to speed up the review of the CE report by expediting their response to our questions on the CE plant. The fact that they also referenced the St. Lucie analysis is not crucial to stif t review.
The staff will base their review only on the CE generic repart.
Ebasco was given a copy of the recently issued NUREG-0609, "Asymmetri'c Blow-down Loads on PWR Primary Systems", which describes the desired methodology for this analysis.
In order to facilitate staff review, Ebasco committed to revise their report to conform to the format of 0609 where possible. Staff also requested that in place of referencing FSAR sections in the report, that a summary of the assumptions and relevant design parameters be incorporated into the text.
This listing of design parameters assumptions will especially help our consultants in their review of the Watertord Unit no. 3 analysis as an independent report.
The intent is to avoid duplication of effort in reviewing the CE generic report.
The dominant break to be used for the fuel analysis will be a single cold icg at the vessel inlet nozzle.
Ebasco will provide the documentation to demonstrate tha. a limited hot leg break will be less than 135 square inches.
The CE generic report showed that a cold leg break was governing for all cases over a limited 135 in.g hot leg break.
Therefore, the cold leg break should also be the dominant break for Waterford Unit No. 3.
The staff requested that 2. dynamic linear elastic timc-history analysis be I
performed on the remainkng ECCS lines attached to the reactor coolant loop.
The results are to be documented in the final report.

- 2' FEB 33 y The staff reviewers from Mechanical Engineering Branch stated that our consultant ORNL should have questions ready by the end of January on the draft Q110.1 response dated 11/14/80. He will contact them to terify tl _
date. Other NRC branches (Core Performance Branch, Reactor Systems Branch, nnd Containment Systems Branch) will also have input in this review of the final report with the 0609 format and additional design information.
The Core Performance Branch was informed that the fuel analysis, which will be plant specific, is scheduled to begin in February and take one year to complete. Ralph Meyer (CPB) stated that the CE topical report should be reviewed and approved by late spring. He suggested a technical meetirig in mid-May in which the applicant should present oreliminary calculations which could provide a means for comparing it to this approved topical report. The staff would hope to obtain enough information at that point to write an SER which temporarily and conditionally closes out this item. This same approach will apply to the MEB input, which will have to wait for the approval of the CE owners group report for final write-off in a SER supplement. The LOCA Asymmetric Load question will be addressed by each branch in their respective sections in the SER.
