SUMMARY

OF OPERATING EXPERIENCE 6-1 Normal plant operation at 431 MWe.

6-2 During normal operation surveillance testing, MSIV position switch ZS 4415 did not provide a closure signal to the RPS within the Technical Specification limit of < 10% closure.

R0 Report 82-34 6-3 MSIV inspection revealed broken cap screws on the speed control manifold assembly for CV 4415 and cracked speed control hydraulic cylinders on CV 4415 and CV 4412.

R0 Report 82-34 _

6-5 Reactor in cold shutdown.

i 6-7 During cold shutdown surveillance testing drywell to torus vacuum breaker CV-4327D was opened and failed to close completely.

i f

R0 Report 82-38 During cold shutdown surveillance testing. RCIC steam line high flow pressure differential indicating switches PDIS 2441 and pDIS 2442 tripped at a setpoint outside the range of Technical Specifications.

R0 Report 82-35 i

i 6-10 During cold shutdown surveillance testing, standby diesel generator 1G-21 l failed to start using the normal air start solenoid.

i R0 Report 82-39 i'

During cold shutdown surveillance testing a leak was noticed in the jacket I cooling system for standby diesel generator IG-21.

R0 Report 82-40 6-16 During cold shutdown surveillance testing electricians discovered manual heater for the "A" standby gas treatment system open.

R0 Report 82-42 6-20 t Repair and leak rate testing of MSIVs undemay.

6-21 During cold shutdown, the NRC Resident Inspector found isolation valve, V-18-07, for SDV level scram switch, LS-1861A, to be open' as required, but not properly locked open.
