. Bertram H. Schur,-. Associate General: Counsel, Atomic Energy Commission, dated August 16, 1971.

(4) Safetv/Reliqf Valve In-Plant Testina (Section 3.8.1. SSER #5)*

Prior to completing the startup test program, Deco shall perforu a series of in-plant tests of the safety / relief valves (SRVs), The acceptance criteria for these tests are contained in Section 2.13.9, "SRV Load Assessment by In-Plant Tests" of NUREG 0661, "NRC Acceptance Criteria for the Marx I Containment Long-Term Program." The results of these tests shall be reported to the NRC staff within six months of completing this test series.

(5) 31!npression Pool Temperatureligasurements (Section 3.8.1. SSER #51 Deco shall accomplish during the first fuel cycle, all the tasks described in its letter dated March 6, 1985, regarding the series of SRV tests which will confirm its methodology for measuring the suppression pool bulk temperature.

(6) Environmental Qualification (Sectign_3dL_SSER #El No later than November 30, 1985, Deco shall environmentally qualify all electrical equipment according to the provisions of 10 CFR 50.49.
