[1 of 1 MAJOR SAFETY-RELATED MAINTENANCE MARCH, 1981 M-1 Gasket leaks were detected on the reciprocating charging pump from a flange in the discharge line.

Replaced the outboard flexitalic gas-ket on No. 1 cylinder of the pump.

Also replaced the gasket on the discharge line of the pump upstream of the pulsation dampener.

The pump tested satisfactorily.

M-2 The air operated cross-tie valve for the Unit 1 and Unit 2 condensate storage tanks, CRV-51, had a blown operator diaphragm.

Replaced the diaphragm and had the valve tested.

M-3 The turbine driven auxiliary feedpump trip and throttle valve was leaking by.

Disassembled valve and found the pilot valve, the stem and the main valve steam cut.

Lapped the seat, replaced the disc and stem, reassembled the valve and had it tested.

M-4 The power cable to motor operated valve, IM0-910, (suction from the refueling water storage tank to the charging pumps) indicated a ground.

The failed portion was removed and reterminated.

The valve was tested following repairs.

~

C&I-l IRV-300, residual heat removal system to CVCS controller indicated 20%

open and the setpoint dial would not turn. The setpoint potentiometer was found loose. The dial was adjusted and the potentiometer was tightened.

l C&I-2 The 50-foot wind direction recorder indication became erratic. The recorder's amplifiers contacts were cleaned and the gain of the am-plifier was decreased to reduce the oscillations. The amplifiar was calibrated and a visual check of the primary and secondary transmit-ters revealed the vanes were, in fact, changing directions rapidly.

C&I-3 SG-18, containment air temperature recorder on the CAS panel failed.

The range module of the ' recorder failed.

The range module was re-placed and the recorder calibration was performed.

l C&I-4 Loop 2, T percent power panel indication was approximately 6% low.

l The normal hot leg RTD was found drifting and not maintaining the

~

l correct value.

The spare hot leg RTD was placed into service and l

R/E module 1TY-421A was recalibrated to the spare RTD resistance l

values.

The failed RTD will be replaced during the next refueling l

outage, i
