_ __UllIT FLAME florth Anna YEAR 1979 DATE 11-5-79 COMPLETED BY W. R. f4ADIS0tl 79-01 (A) Excessive packing gland leakage from fl0V-1700, the residual heat removal system suction valve, of greater than 1 gallon per minute.
Technical specifications permit primary plant unidentified leakage of 1 gpm or less. The unit was rer.oved from service and the reactor shutdown at 1641. The plant was then cooled down and depressurized.
The maintenance was completed on 1-28-79 at 1940. The plant was heated to 547 F on 1-29-79 at 1245 and a leakrate calculation was performed.
Agairi leakage was excessive. It was determined that the pressurizer spray valves were leaking between their bodies and bonnets. The plant was then cooled down and depressurized to allow maintenance. January shutdovin 78-33 continued into February 1979.
