Gus C. Lainas, Chief Containment Systems Branch, TR i THRU: J. Kudrick, Section A Leader, Containment Systems Branch, T MEETING - SOUTHWEST RESEARCH INSTITUTE - JUNE 26, 1975 On June 26, 1975, a meeting was held with members of the NRC staff, the General Electric Company (GE) and the Southwest Research Institute (SRI) in San Antonio, Texas. A meeting agenda and attendance list are enclosed.
The purpose of the meeting was to discuss the seismic slosh test program being conducted by SRI under contract to GE. The objectives of the program are to determine suppression pool response a.nd containment wall pressures for a Mark III containment during an earthquake. The tests utilize a 1/30th scale model of the Mark III containment and pool and the SRI shaker table to simulate the seismic response spectra. Brief highlights of the meeting were as follows:
- 1. The test model simulates the 238 standard plant containment. GE stated that the final report on seismic slosh will include a dis- '
cussion of the applicability of the results to other Mark III designs which might have different containment or suppression pool dimensions.
- 2. SRI indicated that early test results showed that pool velocities in the vertical direction due to seismic excitation were significantly less than those due to pool swell.
- 3. SRI stated that in the 104 frequency range of earthquake spectra containment wall pressures are dominated by suppression pool water slosh whereas in the high frequency range wall pressures are due to pool water inertia effects.
- 4. Testing should be comp 16te in two to four weeks with a final report to be submitted in November or December 1975, hb-<<W.j0AdA Robert L. Cudlin
