DESCRIPTION OF RF@EST: Review and evaluate applicant's submittal (WPPSS i
letter to staff dated 9/3/75) concerning loads on reactor vessel support structure for certain l
postulated IDCA's.
As part of the report on l
the generic concern for reactor pressure vessel supports, WPPSS has presented a revised sub-compartment pressure differential analyses l
based on their recent addition of guani pipes t
l on reactor vessel hot and cold legs within the
~
reactor compartment. Project staff requests prompt review of guard pipe design and sub-compartment differential pressure analyses in ordor to avoid carrying this issue as.m open iten into the post CP period. A radiological I
safety hearing on this application las been tentatively scheduled by ASLB for 11/4/75, i
j with testimny required by 10/15/75.
