MEETING WITH SOUTHERN CALIFORNIA EDISON COMPANY SAN ONOFRE-NUCLEAR GENERATING STATION UNIT NO. 1 DECEMBER 1, 1981 AGENDA
- 1. Structural Details of the Fuel Storage Building A. Drawings B. All Calculations and Results of All Analyses
- 2. SCE's Response to the Following Questions:
A. Why does the Spent Fuel Building require extensive modification to meet 0.67g Housner siesmic input while reanalysis of other Category A structuers, which were origininally designed to 0.5g Housner DBE, did not require modifications?
B. What is the structural capacity of the existing Spent Fuel Building?
C. What are the limiting structural members? Is the problem limited to Block Walls above the 42 foot elevation and the roof fr'aming?
D. What are the safety consequences of possible structural failures?.
The effect on decay heat removal systems and the effect upon stored spent fuel should be identified?
E. Based upon the seismic hazard at the site, what is an appropriate schedule for implementation of any necessary modifications? The licensee's current schedule would provide preliminary results.for the Spent Fuel Building by January 31, 1982.
The licensee has not provided a schedule for implementation of modifications for this structure; however, the staff has required a schedule and case-by case justification for any modifications necessary to meet 0.67g Housner SSE which are not implemented by January 1, 1983.
- 3. Any SCE's comments Related to Other Sections of SER Dated November.16, 1981, Regarding Interim Seismic Adequacy with Regard to Availability Applicability, and Correctness of SCE's Supporting Information.
- 4. General Discus'sion of the Methods of Analysis for Other Masonry Load Carrying Walls in Category A Structures.and masonry walls whose failure or displacement could adversely affect the performance of safe shutdown equipment.
