INTERFACE REVIEW FOR CESSAR ArtJ WA5kINGTON PLBLIC POEA SUPPLY SYSTEM, WP 3 AND 6 Plant Name: Washington Public Power Supply System, WP 3 & 5 Docket hos.: 50-508/509 Licensing Stage: CP NSSS Supplier: Coabustion Engineering l-Architect Engineer: Ebasco l

Containment Type: Dry, Dual Responsible branch & Project Manager: L W 1-3; P. O'Reilly Requested Completion Date: August 6, 1975 Applicant's Response Date: N/A Review Status: Lomplete In accordance with your request of July 25, 1975, the Containment Systems Brarx.n has performed a coordinated review of the optional systems and interfaces contained in CESSAR and WP 3 and 5.

We have concluded that optional systems referenced in CESSAR are not l

applicable to tne WP 3 and L containment systems, l

l With regard to interface items, CESSAR proposed using containment high pressure as the only isolation signal, which we concluded was not acceptable. Combustion Engineering has been advised that diverse con-taiment isolation signals will be required. Since WNP 3 and 5 uses the saine containment isolation activation signals as CESSAR, this is i

an open item which will require resolution with the applicant. Com-bastion Engineering intends to amend CCSSAR November 30, 1975, to address this issue.
