9-1 Normal operation at 211 Nie net. , ,.

9-2 During norm'al operation, while investigating a " river water intake

. system IC-102 trouble" alarm, HS-2960B was found in the 'off' position.

HS-2906B is the mode switch for IP-112B, the 'B' . river water supply (RWSS) traveling screen wash pump. , 'B' RWSS was declared inoperable.

R0' Report 82-057 9-10 During normal operation, the 'B' RWSS traveling sc een 1F-368 would ,

not run in either ' auto' or ' continuous' mode. The 'B' RWSS was declared inoperable.

, R0 Report 82-058 .

9-10 During normal operation, workmen in the RCIC rocm reported a marked l increase in room temperature. Subsequent investigation revealed that  !

. ..the drive. belt for RCIC. room cooling unit.IV-AC-15A.was broken. . Since ._ . . _

.]

redundant IV-AC-15B was inoperable for repairs, RCIC: pump 1P-226 was j inoperable.

1 R0 Report 82-059 9-10 During normal operation, the 'B' RWSS traveling screen 1F-36B would not run in either ' auto' or ' continuous' mode. The 'B' RWSS was l declared inoperable. l 1

R0 Report 82-060 l 9-12 During normal operation, HPCI steam supply isolated due to erroneous signal from TDS-2260A. HPCI was declared inoperable. Upon operability testing, HPCI did not meet fast start requirements. ECCS subsystems testing resulted in RCIC declared inop. due to turbine trip.

. R0 Report 82-056 9-14 ,

During normal operation, RHR Service Water pumps ' A' and 'D' failed to ,

meet Teqhnical Specification flow and head requirements during testing.
