_R1QQEST I'OR ADDITIONAL It!F013% TION In your letters dated July 1 and lioverber 8,1977 you stated that the con-tainment purge isolation system is required to function to mitigate'th; con-sequences of a fuel handling accident inside the containment (FIMIC). Any systems required to maintain the conservatively calculated consequences of an accident below Part 100 exposure guidelines should be considered engineered safety fectare systeir.s.
Provide system descriptions (including P&lD's cnd control system logic and schematic diagrams) and analysis to demonstrate the extent to which existing systems required to function during the FHAIC comply with the criteria established in the Hezards Summary Report for engineered-safety features.
Provide also a description of the extent to which thcsc sys-tems will comply with the current IIRC criteria for engineered safety feature systems which is listed in the flRC Standard Review Plan, tiUREG-75/OS7.
Ex-plain why it is not necessary to have these systems meet the current llP.C cri-teria for ESF systems.
lhe information that you should provide for any changes to the existing plant is described in Regulatory Guide 1.70, I
