| |
| 50-302/81-004/03L-0 Facility:
| |
| Crystal River Unit 3 Report Date:
| |
| 16 Fecruary 1981 Occurrence Date:
| |
| January 19, 1981 Identification of Occurrence:
| |
| Inoperable position indication for containment isolation valves contrary to Technical Specification 3.6.3.1.
| |
| Conditions Prior to Occurrence:
| |
| Mode 1 power operation.
| |
| Description of Occurrence:
| |
| At 0113 af ter routine sampling of the Reacter Coolant System, it was discovered that containment isolation valve CAV-2 indicated both open and closed.
| |
| CAV-1, 3, and 126 were closed and deactiva-ted. Maintenance was performed and operability was restored at 0600. At 0648 while restoring CAV-126 to service it was aiscovered that the cloeed position indication would not actuate. CAV-2 was closed and deactivated; CAV-133 was closed. Maintenance was perfcrmed and operability was restored at 1327.
| |
| Designation of Apparent Cause:
| |
| The cause of CAV-2 indication failure is unknown at this time.
| |
| CAV-126 indication failure was caused by defective breaker in the main power supply to the valve.
| |
| Analysis of Occurrence:
| |
| There was no effect upon the health or safety of the general public.
| |
| I Corrective Actiori:
| |
| An engineering investigation is in progress to evaluate problems associated with CAV-2. The system breaker for CAV-126 was re-placed and a functional test for CAV-126 was satisfactory. The engineering investigation for CAV-2 is REI 80-1-11.
| |
| Failure Data:
| |
| This was the sixth occurrence for CAV-2, the second occurrence for CAV-126, and the thirty second event reported under this Specification.
