- ML19345B811 - LER 80-069/01T-0:on 801112,water for lubrication & cooling of A train svc water pumps found to be provided by B train water header & vice versa.Caused by design error.Design change to provide correct separation completed. (2 page(s), 11/26/1980)
- ML19345B816 - LER 80-066/03L-0:on 801026,containment atmosphere particulate & gaseous radioactivity monitoring sys (R11 & R12) declared inoperable.Caused by clogged filter paper from stuck filter paper takeup reel causing pump low flow trips. (1 page(s), 11/26/1980)
- ML19345B823 - LER 80-068/03L-0:on 801031,B train river water pumps declared inoperable due to inadequate lube & cooling water flow.Caused by dirty strainers.Strainers blown down & cleaned. (1 page(s), 11/26/1980)
- ML19345B829 - LER 80-070/03L-0:on 801028,svc water bldg train A battery sys declared inoperable due to low cell specific gravity. Caused by close terminal proximity & poor post seal design allowing formation of acid residue which shunted current. (2 page(s), 11/26/1980)
- ML19345B833 - LER 80-071/03L-0:on 801027 & 28,containment atmosphere particuulate & gaseous radioactivity monitoring sys (R11 & R12) declared inoperable due to low flow pump trips.Caused by failing bearings & partially opened isolation valve. (2 page(s), 11/26/1980)
- ML19345B840 - LER 80-072/03L-0:on 801031,river water train B declared inoperable when pump 5 tripped & would not restart.Caused by breaker HEA 86 lockout relay & 50G instantaneous overcurrent relay actuation. (1 page(s), 11/26/1980)
