MONTHLY NARRATIVE REPORT OF OPERATION AND MAJOR MAINTENANCE EXPERIENCE This report describes the operating and major maintenance experience for the month of April,1985. This narrative report was prepared by the plant staff and is submitted in accordance with Section 6.9.1.10 of the Unit 1 Plant Technical Specifications and Section 6.9.1.7 of the Unit 2 Plant Technical Specifications.

The Unit 130-day outage started on March 28 was continued through the month of April. The primary accomplishments are as follows;

1. Containment Integrated Leak Rate Test,
2. Removal of startup strainers,
3. Maintenance,
4. Regulatory Guide 1.97 required modifications, and
5. Surveillance testing necessary to permit operation for the balance of the fuel cycle with no additional planned outages.

The major safety related maintenances performed in the month of April 1985 are as follows:

A complete inspection of inaccessible snubbers was completed for the Unit 1 containment.

A Unit 1 Pressurizer Safety Valve was lapped to stop a leak.

The bearing mounting plate for all five Unit 1 containment fan coolers was modified to resolve a vibration problem.

The Unit 1 containment fan cooler motor leads were reterminated to correct high resistance connections.

No challenges to the PORVs or Steam Generator Safety Valves have been made.

No changes have been made in the Offsite Dose Calculation Procedure, the Environmental Radiological Monitoring procedure, or any radioactive waste treatment. system.
