SUMMARY
OF MEETING WITH MAINE YANKEE ATOMIC POWER COMPANY ON OCTOBER 18, 1979, TO DISCUSS THEIR ASYMMETRIC LOCA LOADS EVALUATION, IN BETHESDA, MARYLAND The NRC staff met with Maine Yankee Atomic Power Company on October 18, 1979, to discuss their schedule and status for the Asymmetric LOCA Loads Evaluation.
The approach chosen by Maine Yankee was to perfom an analysis taking credit for break area limiting devices. The analytical work proposed by Maine Yankee will be a simplified analysis taking credit, where applicable, for analysis perfonned on sin 1ilar structures.
The proposed modification to limit the break area, of the postulated rupture at the RPV nozzle, has been assessed by M.Y.A.P.C. and can be performed during the planned January 1980 outage. The proposed modification will not interfere with required ISI of the RPV nozzles or impose any additional loadings on the primary system.
The staff agiees with this approach in concept and informed the representatives from Maine Yankee, in the meeting, that details of both the modification and the analysis should be submitted to the staff for review as soon as possible.
