1 of 1 MONTHLY OPERATING ACTIVITIES - APRII., 1982 Highlights:

The Unit entered the reporting period in Mode one, the Unit had just been paralleled at 2215 hours0.0256 days <br />0.615 hours <br />0.00366 weeks <br />8.428075e-4 months <br />, March 31, 1981. Prior to reaching 100%, the West Feed Pump tripped when an operator tried to clear the low vacuum trip operated alarm annunciator.

Power was rapidly reduced to 45%. The Feedpump turbine was reset and the Unit reached 100% power at 1208 hours0.014 days <br />0.336 hours <br />0.002 weeks <br />4.59644e-4 months <br />, April 2, 1982.

Power was reduced to 80% on April 7,1982 to conduct condensate flow tests.

Power was started down April 22, 1982, when it was thought that the Boron Injection Tank was not within its required boron con-centration limits.

Less than 1% power was dropped before the tank boron concentration was verified correct.

Power was again reduced to 85% on April 30, 1982 to conduct condensate flow tests.

Summary:

4-1-82 1410 hours0.0163 days <br />0.392 hours <br />0.00233 weeks <br />5.36505e-4 months <br />, West Main Feedpump turbine tripped, power was reduced to 45%.

4-2-82 1208 hours0.014 days <br />0.336 hours <br />0.002 weeks <br />4.59644e-4 months <br />, power returned to 100%.

4-7-82 2207 hours0.0255 days <br />0.613 hours <br />0.00365 weeks <br />8.397635e-4 months <br />, power reduced to 80% for condensate flow tests.

4-8-82 0840 hours0.00972 days <br />0.233 hours <br />0.00139 weeks <br />3.1962e-4 months <br />, power back to 100%.

4-8-82 0648 hours0.0075 days <br />0.18 hours <br />0.00107 weeks <br />2.46564e-4 months <br />, Number 24 Circulating Water Pump motor tripped due to motor grounded.

4-9-82 0358 hours0.00414 days <br />0.0994 hours <br />5.919312e-4 weeks <br />1.36219e-4 months <br />, Number 24 Circulating Water Pump motor was replaced.

4-14-82 On two occasions, one half of a Main Turbine Condenser was removed from service for a leakage test, two tubes were plugged.

4-22-82 Power was reduced less than 1% for a few minutes due to an indicated high boron concentration in the Boron Injection Tank.

4-29-82 2153 hours0.0249 days <br />0.598 hours <br />0.00356 weeks <br />8.192165e-4 months <br />, power reduced to 85% to conduct condensate flow tests.

4-30-82 0920 hours0.0106 days <br />0.256 hours <br />0.00152 weeks <br />3.5006e-4 months <br />, power returned to 100%.

Re-placed the valve bonnet and diaphragm.

M-2 The east centrifugal charging pump mechanical seal was leaking.

Re-placed the seal and had the pump tested.

M-3 The hot leg manway cover on No. 2 steam generator was leaking.

Re-placed the gasket for the hot leg manway cover.

Retorqued the bolts for the cold leg manway.

M-4 The west centrifugal charging pump mechanical seal was leaking.

Re-placed the inboard seal and realigned pump to motor. Had the pump tested.

M-5 No. 2 steam generator power-operated relief valve, MRV-223, had a body-to-bonnet leak.

Lapped the valve seat and replaced all gaskets. Had the valve tested.

M-6 No. 2 steam generator stop valve dump valve, MRV-232, was leaking by.

Replaced the seat ring and the gaskets. Had the valve tested.

M-7 The south boric acid filter outlet isolation valve, CS-421S, was leaking.

Replaced the diaphragm.

M-8 No.1 steam generator power-operated relief valve, MRV-213, was leaking by.

Replaced the plug and cage.

Reassembled with new gaskets and had valve tested.

C&I-l Emergency Diesel generator 'AB' could not be shut down by the control room 'stop' switch nor by an HEA relay trip. The generator was finally shut down by repeated actuation of the local panel emergency trip. A diaphragm and valve seat o-ring on trip valve POV-4 were replaced to restore the proper trip function to ' AB' diesel.
