.Cear 14n. Ceters in our Ictter. (BLt-03) to you of June 20.1984, 5cchtel suggested the vortical review portion of the Cilnton Pownr Station 10R be tia':cd on two the high pressura core sitray system.(HrC5) and the Class 1-r at sytests:
These systes permit a congirehensive rt.vfew of electrical power. systte, design activities both functional and discipline related. In additicn to the direct. system. design, design of etiter faellities will ha considered associated. For where they are physically coupled or othetwisc closelyltting evaluation of each systwa installation should tea well advanced pcte tite full range of AE at.tivitites.
the systes permit assesservit of the AE Frem;the functional standpoint, t-itS55 interface, and design Interfects t

They pitvida good exaagiles of retcrunt engineering and design activities including seismic considwation$s nuclear, safety analysis.
