a MONTHLY NARRATIVE REPORT OF OPERATING AND MAJOR MAINTENANCE EXPERIENCE This report describes the operating and maior maintenance experience for the month of September, 1978. This report was prepared by the Plant Staff and is submitted in accordance tith Section IX.I.1.c. of the Technical Specifications.

During the report period the reactor remained in the cold shutdown mode of operation. There were no significant events associated with the operation of the Unit. The following significant maintenance was completed during the month:

1)

No. 3 Screen Wash Pump - The pump performance decreased significantly and the pump was removed from service. The performance decrease was due to plugging of the suction bell by shells. The pump was overhauled, the pump pit cleaned, a pump suction strainer fabricated following a 10CFRSO.59 review and the pump returned to service.

2)

No. 3 Fire Pump Relief Valve - The pump was removed from service following the lifting and only partial reseating of the relief valve. The relief valve seat was cut and the sten galled. An investigation was initiated te determine if the valve performance could be improved and it was discovered that the valve had not been designed for horizontal installation (present method of installation).

The valve was overhauled and the piping modified for proper vertical installation following a 10CFR50.59 review.- This item is the subject of LER-78-003/03L-0.

3)

Radwaste Vent Monitor - The monitor failed high due to degraded electronic components. The unit was overhauled and returned to service.
