~Summa r 08/03/79 -- Loop 1 Overtemperature and Overpressure 6 T Protec-tion was placed in the "trip" mode due to a low flow alarm on Loop 81 RTD Bypass.
Trouble was located in the alarm rather than low flow.
The alarm was repaired and the instrumentation was removed from the "trip" mode.
Total time in trip mode was 7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br />.

No leaks were located.
08/05/79 -- Control Rods became inoperable in the "Automatic" mode due to an urgent failure alarm.
The rods were still capable of being driven manually.
Repairs were made and the automatic feature became operable 8/6/79.

The flow went to full 'scale on the recording chart (6 gpm).
The flowmeter was bypassed reducing indicated flow to 3 gpm.
Since then the indicated flow has varied from a high of 3.'43gpm to a low of 2.7 gpm.with an estimated 3
gpm through the bypass.
This leakoff flow is being carefully observed.,

The low level alarm 5'23 RCP motor upper oil reservoir annunciated.
The oil level in the sight glass of this reservoir is being monitored by closed circuit tele-vision and the bearing"temperatures are being trended on the computer.

Generator loading suddenly dropped"and recovered(
"approximately,250 Mw while testing >>Turbine valves.
~ The "C" Main Stop and Control,Valve was being tested.
The test sequence is for the control valve to close first and then the stop valve.
As the control valve started to close, the stop valve immediately closed causing the load spike.
The test circuit for this set of valves was thoroughly checked but no problem was found.
A subsequent test of these valves on 8/25/79 was normal.

Backwash valve retainer nut tightened and staked.
Operation is satisfactory.
No.
1 steam generator blowdown containment isolation valve, DCR-310 closed for no apparent reason.
A hole was discovered in the diaphragm of the valve operator.
Replaced the diaphragm and had valve retested.
HARV-422, primary water to the boric acid blender, failed closed.
A capacitor in the controller failed and was replaced with a spare capacitor.
The controller calibration was performed and operationally tested.
The loop ¹1 RTD Bypass Return Flow Low Alarm was received in the control room.
The associated bistables were placed into the trip mode during the investigation of the problem.
A ground condition was identified in the pull box located near the indica-ting alarm switch NFA-210.
The ground was cleared and the bistables returned to normal.
The Fire Protection actuation alarm on 2 HV-AES-1 was received in the control room.
Water was found in the manual actuation switch box.
The switch box was dried and a small drain hole in the bottom of the box was added to prevent future water accumulations.
The source of the water could not be determined.
The limit switch on the main turbine control valve A was indicating arcing of the contacts.
The burned contacts were replaced and the switch operation verified.
Main Turbine Stop Valve A would not operate during weekly surveillance testing.
After repairing a broken wire in the limit switch the valve was tested satisfactorily.
Pressure channels 1 and 2 of loop 2 steam generators differed by 30 psi.
Pressure channels 1 and 4 of loop 4 steam generator differed by 30 psi.
In both cases, the 28 psi differential notification limit was exceeded.
Outputs of all loop 2 transmitters were checked and were found to be within 15 psi.
Indicators were then calibrated.
Outputs of all loop 4 transmitters were checked and were found to be within 7 psi.
Channel 1 indicator and cu'rrent repeater were calibrated.
