Replaced the valve cage, machined the plug and the bonnet gasket face, reassembled with new gaskets and repacked the valve.

Had the valve tested.

M-2 No. 4 steam generator blowdown regulating valve, DRV-342 had a body-to-bonnet leak.

Replaced gaskets and had valve tested.

M-3 The safety injection pump discharge crosstie motor operated valve, IM0-270 would not operate. The valve operator motor was burned up.

Replaced the motor, adjusted limit switches and lubricated the shaft.

Had valve tested.

M-4 The inboard fan bearing on ventilation unit, HV-AES-1 (Engineered Safe-guards Features Ventilation) was running hot.

Replaced the fan bearings.

M-5 Emergency boration valve to the charging pump suction, QM0-410 would not open.

Replaced the stem, disc, backseat and position indicator.

Repacked the valve and had it tested.

C&I-l CFA-450, component cooling water flow to the reactor coolant pumps indi-cated approximately 200 gpm with the return flow indication at full scale.

The instrument loop was tested and the square root extractor required recalibration.

The instrument loop indicated 800 gpm when returned to normal service.

C&I-2 Reactor Coolant Pump No. 2, thermal barrier differential pressure low alarm was received with a seal injection flow of 8 gpm.

The calibra-tion of QDA-21 was tested and determined to require recalibration.

Following the calibration the alarm cleared.

C&I-3 WFI-721, essential service water flow from the AB diesel generator, indication would vary dufing a zero flow condition.

The transmitter's i

printed circuit board was replaced and the instrument was recalibrated and returned to service.

C&I-4 The, diesel fire pump fuel oil tank level gauge failed to indicate the correc,t level.

The gauge required replacement.
