\\<v-31 ATOMIC ENERGY COMMISSION WASHINGTON, D.C. 20545 rn c November'21, 1972 Docket No. 50 155 Con umers Power Company Am:
Mr. Ralph B. Sewell Nuclear Licensing Administrator 212 West Michigan Avenue Jackson, Michigan 49201 Change No. 33 Gentlemen:
License No. DPR 6 We have reviewed your request dated July 20, 1972, that proposed a change to the Technical Specifications of Facility License No. DPR-6.
The proposed change concerns the testing of the explosive actuated valves of the liquid poison system.
From telephone discussions with members of your staff, we understand tha t the test firing of explosive primers will utilize the normal actuation circuit, but will only energize one primer ot the two per valve, and that post-test inspection will confirm that both primers have fired. We conclude that the test should be performed in this manner.
Based on our review of your request, we have concluded that the proposed change is an improvement in the existing specification and does not present significant hazards considerations not described or implicit in the Big Rock Point Safety Analysis Report. There is reasonable assurance that the health and safety of the public will not be endangered by operation in the manner proposed.
Accordingly, pursuant to Section 50.59 of 10 CFR Part 50, the last sentence of Section 5.2.3 of the Technical Specifications of Facility License No. DPR-6 is replaced by the following:
"One squib primer and trigger assembly from the equalizing line shall be removed and test-fired at least every 12 months.
These shall be tested on an alternate basis insuring valve replacement every two years. One squib primer and trigger assembly from the remaining five units shall be removed and I hereby certify that this a true and correct copy of the original k'y
