SUMMARY

At the beginning of the month the plant was operating at full power.Qn April 5, the plant experienced an automatic scram resulting in about'6 days of forced outage.Following the forced outage, the plant restarted and operated an additional 11 days then plant shutdown for the annual refueling outage on April 22.TYPE F-Forced S-Scheduled REASON A-Equipment Failure B-Maintenance or Test C-Refueling D-Regulatory Restriction E-Operator Training&License Examination F-Administration G-Operational Error H-Other METHOD 1-Manual 2-Manual Scram 3-Auto Scram 4-Continued 5-Reduced Load 9-Other SYSTEM&COMPONENT NUREG%161 Exhibits F&H AVERAGE DAILY UNIT POWER LEVEL REPORT PERIOD: APRIL 1995 DOCKET NO.: UNIT: DATE: COMPLETED BY: TELEPHONE:
