1RPRRTIVE Sutt9RY OF FOffIHLY OPEPATDIG EXPERIDJCE UNIT 1 OCIOBER 1993 October 1 'Ihe Unit operated at a nominal value of 100% output.

through October 11 October 12 At 1507 hours0.0174 days <br />0.419 hours <br />0.00249 weeks <br />5.734135e-4 months <br /> the Unit experienced a loss of the majority of offsite load Valley when ten offsite feed breakers in the Beaver switchyard opened as a result of inadvertent underfrequency system separation. We large load reduction caused the turbine to trip on nechanical overspeed and resulted .

in a "high flux rate positive" reactor trip. The opening of '

the switchyard feed breakers arx1 the resultant turbine generator trip resulted in a loss of offsite power to both Beaver Valley Units 1 and 2. Offsite power was restored to both Units at 1517 hours0.0176 days <br />0.421 hours <br />0.00251 weeks <br />5.772185e-4 months <br />. 'Ihe Unit remained in Mode 3 to '

ccuplete required inspections on the RCS Protection RID's.

October 13 The Unit initiated a cooldcun to Mode 5 at 1110 hours0.0128 days <br />0.308 hours <br />0.00184 weeks <br />4.22355e-4 months <br /> due to pressure boundary leakage from the Loop 1A Cold Irg Isolation Vent [1RC-27). Mode 4 was entered at 1747 hours0.0202 days <br />0.485 hours <br />0.00289 weeks <br />6.647335e-4 months <br />.
