- 3. Report Date: 28 April 1977
- 4. Occurrence: 6 April 1977
- 5. Identification of occurrence:
In the process of moving Group 8, Axial Power Shaping Rods (APSR's),
the absolute position indicaor for Rod 5 failed causing a condition contrary to Technical Specification 3.1.3.3.
- 6. Conditions Prior to Occurrence:
Normal Mode I operation. -
- 7. Description of Occurrence: 2 At 0812, while adjusting a power imbalance wit! Group 8 Rods, absolute pcsition indicator for Rod 5 failed. Rod posi*. ion was verified by the Rod Zone Limit Switch. Commenced logging position agreement between r reference indicator and the operable position indication as per SP-300.
l ( Position indicator for Rod 5 was restored operable during shutdown on 8 April 1977.
- 8. Designation of Apparent Cause of Occurrence:
The amphenol connector to the position indicator was found to have a faulty pin connection.
- 9. Analysis of Occurrence:
There were no safety implications as the Reactor could have been safely shut down at any time.
- 10. Corrective Action:
The amphenol connector was repaired and absolute position indicator for Rod 5 of Group 8 was restored operable.
- 11. Failure Data:
This occurrence wat non-repetitive for the APSR group.
