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
