50-281 80-025/03L-O EVENT DATE: 10-03-80 TITLE OF REPORT: HEAT TRACING FAILURE

1. Description of Event:

With Unit 2 at 100% power, Pe.riodic T.est 27D revealed that the amp readings for circuit 2A Panel.10 (Unit #2 BIT inlet line and valv.es) were below the Acceptance Criteria stipulated in the PT. This is a degraded mode of operation as specified in T.S.3.3.B.5 and is re-portable in accordance with T.S.6.6.2.b(2).

2. Prob ab le Consequences & Status of Redundant Systems:

The Heat Tracing is intended to ,maintain a temperature above that needed for flow. The redundant Heat Tracing Circuit was operable, therefore, the.health and safety of the public were not affected.

3. Cause:

The *Heat Tracing Tape was damaged during ..erection of scaffolding to support* mechanical work in the nearby area.

4. Immediate Corrective Action:

The immediate corrective action was to verify that the redundant circuit was operable.

5. Subsequent Corrective Action:

The defective Heat Tracing Circuit was replaced within the time span specified by the Technical Specifications.

6. Action Taken to Prevent Recurrence:

No additional *actions are deemed necessary.

7. Generic Implications:

The task force has reviewed the total. spectrum of the Heat Tracing sys tern and a Design Change is being prepared as a .result of the Task Force Study. Long lead items are b.eing procured .
