20555 N3 1375 R. C. DeYoung, Assistant Director for Light Water Reactors, Group 1 Division of Reactor Licensing GRAND GULF 1 & 2 SUPPRESSION POOL DYNAMIC LOADS (TAR-1579)
In accordance with your request dated April 29, 1975, the Mechanical Engineering Branch has reviewed the applicant's report dated April 25, 1975 concerning suppression pool dynamic loads. We found that the submittal f rom Mississippi Power and Light Company to NRC does not contain any needed information for assessing design adequacy of piping and mechanical components ef fected by suppression pool dynamic loadings or loadings from operation of the primary system pressure relief valves.
Enclosed is our request for information. Our completion of the evaluation is pending on the availability of the specified information.
