OPERATIONS

SUMMARY

f The unit was shutdown the entire month by order of the NRC.

Core cooling was provided by the Decay Heat Removal System. With OTSG repairs completed, a hydrogen peroxide flush of the RCS was performed to remove deposits of sulfur contamination.

In conjunction with the flush the following cujor components / systems have been exercised: reactor coolant pumps, CRDMs, makeup pumps, and pressurizer.

Additionally, most primary support systems were also run during the month and vacuum was drawn in the secondary. Near the end of the month, a comprehensive program of ESAS testing was commenced that lasted into the following month.

To date, all components and systems have run with little or no problems.

MAJOR SAFETY RELATED MAINTENANCE The following major maintenance occurred during the month:

DH-V14B Repair DH-V14B was found to be leaking through and was disassembled. The seat ring was replaced and the valve reassembled and tested satisfactorily.

DH-VSA The magnetic brake on DH-V5A was replaced in order to upgrade the valve for more severe environmental conditions.

The valve was then tested satisfactorily.

Local Leak Rate Testing This program continued with the satisfactory testing of EM-V4A and LR-V49.

Valve Operator Thvrectors Change Out Thyrectors in 22 of 47 valve operators were. replaced. The replacement was necessary to i=orove the environ = ental cualification.

The remain-ing thyrectors will be replaced next month.

Purge Valves Hard stops were installed in AH-V-1B and C to prevent their discs from drifting past their intended seat oosition. AH-Vlc tested satis-factorily. AH-VlB will be tested next month.

Snubber Testing The snubber testing and repair progrs= continued during the month.

No failures were identified.
