MMG 1981 I

At the beginning of the reporting period, the Oyster Creek Nuclear Generating Station was operating at 91% capacity (595 IWe) limited by condensate A-4navalizer differential pressure. Se ultimate cause of the differential pressure limitation

, is the in=h414ty of the New Rachaste Facility to es liquid waste from the regeneration of the n-inaralizers as designed. Full load was attained on March 4.

At the end of the reporting period, a startup was in p%& css and load increase was being delayed to cmplete a required Eirau.py Drill.

Se plant was shut down twice during March for maintenance. A shutdown occurred on March 12, 1981 to repair steam leaks in the c el - ar Bay to facilitate maintenance on "A" North Waterbox which was causing high conductivity in "A" Hotwell. On March 28, 1981, the plant was shut down to correct an increasing

. leak rate in the primary contairnent. We main cause of the leak rate increase l was "C" Recirculating Pm p Seal and a leak in 1-5 Drywell cooler.

Bere were 5 Reportable Occuisia. es identified during March.

R. O. 81 - 10 was identified on March 2,1981 when the setpoint on Main Steen Line Hi Bad Monitor #2 was found to be less ocnservative than Tech Spec requirements.

R. O. 81 - 11 was identified en March 7, 1981 when the setpoint on the Telaticn Cbndenser Linebreak Sensor was found to be less conservative than Tech Spec requirements.

a l R. O. 81 - 12 was identified on March 13, 1981 when the setp ints on ERV's 1A83C & E were found to have settings less ocnservative than Tech Spec requit=-d.s.

I R. O. 81 - 13 was identified on March 19, 1981 when the setpoint for Core Spray Hi Drywell Pressure Switch RV 76B was found to have a setting less conservative than Tech Spec requirements.

R. O. 81 - 15 was identified on March 27, 1981 when the setpoints for Main Steam Line Break Sensors RE 22 F & G were found to have settings less ccuservative than Tech Spec requirements.
