PRIMARY PLANT SELF-ACTUATED RELIEF VALVE OPERATION. CORE 1, SEED 3. Section 2. Test Evaluation, DLCS-3070202

Technical Report ·
OSTI ID:4829524
ABS>Tests were carried out to insure the reliable operation of the four self-actuated reactor coolant loop relief valves and the four self-actuated purification system relief valves. The valves operated properly, and the final set pressures were all within the prescribed limits (2530 plus or minus 50 psig) except that of the 1BD hairpin loop. The set pressure of this valve was accepted since it exceeded the lower limit by only 3 psig. The valve temperatures which were measured before the manual flush of each relief valve indicated that there was no excesstve leakage. (M.C.G.)
