7 1.0 WPPSS_ Introduction and Genersi Description L. lhanphreys, Deputy !!anaging Diractor for WPPSS, described the applicants organization an1 function, its relationship with its rannber utilities, and the nuclear power plant experience of their personnel. He described the WPPSS quality assurance (QA) program and its function within the overall l
WPPSS organization.

2.0 Report by the Staff,f T. Cox presented the outstandini; issues in the review of the tr.TT-1,4 application. At SER issuance on May 2, 1975, there were 18 issues, of which 8 had becu resolved prior to the ACRS Subconmittee necting.
Of the remaining 10 itens. 4 were expected to be resolved by mid-A ne 1975, 2 others (ECCS and the ultinate beat sink) by mid-July 1975, and 4 were generic items for which staff revicw is expected to extend beyond the date of issuance of a construction parnit. A brief utatus report on these generic reviews was presente:d.

of their in-plant heat rejection systems may reveal that they do not have a problem in meeting the staff requirement of 25% maximum assumed spray nozzle array efficiency. WPPSS analyses are expected to be complete and a proposed resolution of this issue offered to the staff by June 5, 1975, 4.0 WPPSS Technical Presentation WPPSS' technical presentation covered (1) site characteristics, (2) on-site and off-site power sources, (3) environmental surveillance, (4) emergency planning and industrial security planning, (5) course-of-accident instrumentation, (6) comparison of the WNP-1,4 NSSS with Bellefont and Greenwood, and (7) containment structural design and performance under accident loads.
5.0^ ACRS Subcommittee Comments The following are the comments or questions made by the subcommittee members during the presentations which may be addressed at the full connittee meeting. Numbers in parentheses indicate the page and line location in the offical transcript of the meeting.

In event of total loss of offsite power and failure of diesel generators, you ceram the reactor and have shutdown reactor batteries but no diesal power.
Car. you surv1' e this situation (141-20).
