DOCKET 50-155, LTCENSE DPR BIG ROCK POINT PLANT Transmitted herewith are three (3) executed ana thirty-seven (37) conformed copies of a request for a change to the Technical Specifications of License DPR-6, Docket 50-155, issued to Consumers Power Company on May 1, 196h for the Big Rock Point Plaat.
1 This proposed change pro ~ ides enhanced operability and surveillance require-ments for the core spr4 systems, modifies the automatic actuation requirements of the containment spray systems such that the interlock between M0-706h cnd MO-7068 <an be eliminated, and changes the allowable operating pressure to be consistent with the ECCS analysis submitted July 25, 1975 Also attached is an analysis of ECCS performance for the case of a break in the ring core spray line assuming only reflooding from the nozzle spray system and feed-water system. This analysis shows that the core is never uncovered.
