SUBJECT:
TECHNICAL FEVIEh PEPORT: "FLOCDING 0F SAFETY-PELATED VALVES IN P!T5" The subject Technical Review Report is encicsed for your information.
Between February 35 and 18, 1985, testing of the recirculation spray valves at L' orth Anna Unit 1 indicated that one of these valves was sticking ir. the 75%
open position. Maintenance personnel found miner-1 deposits on the valve yoke nd and valve stem which prevented the valve from operating properly. Tt e valve had beer submerged and impurities in the water had solidified on the valve.
Groundwater infiltration is a chronic problem at the North Anna site.
This particular problem does not appear to have ceneric implications.
It can, however, have safety implications for specific sites.
The resident inspector
.s tracking North Anra's resolution of the problem.
AEOD plans no further action.
