Tha generic grouping studies reduced the Westinghouse plants to -

five (5) rajor gre y .

_ Scoping analyses results were presented for four (4) break locations on the stea', generator and reactor coolant pump sup; orts. The raxirum piping stress (elastic analysis) resulting from each of the breaks consicered was also presented for each plant.

The steau generator support loads presented did not include the affects ,

of stean generator cavity pressurization. The Westinghouse owners stated that preliminary investigations indicated that the contribution of S.G. .

cavity pressuri:ation would be snali and requested that the staff participate in a working group session to potentially eliminate this part of analysis. The staff requested that the Westinchouse owners -

investigste potential f6r 5.G. cavity pressurization for sHrt mWted steirgenerators. A working group session win be scheduled to resolve chis issue. -
