SUPPLEMENTARY INFORMATION (V') -l. Report Nc. 50-302/77-53
- 2. Facility: Crystal River Unit #3 3: Report Date: 20, June 1977
- 4. Occurrence Date: 29 May 1977 , _ _
- 5. Identification of occurrence:
Chemica1' addition pumps CAP-3A & 3B inoparable contrary to Technical Specification 3.1.2.2.
- 6. Conditions Prior to Occurrence:
The plant was preparing to achieve' criticality by adjusting boron for the accept-able critical rod position..
- 7. Description of Occurrence: l At 0700 in preparation for criticality, an attempt to adjust Reactor Coolant boron f-concentration for acceptable critical rod position revealed that r.either chemical addition pump CAP-3A or CAP-3B would deliver boric acid to the makeup tank. -Both chemical addition pumps were flushed with demineralized water and the pumps restored operable within two (2) hours. Startup resumed without incident. ,
- 8. Designatio'n of Apparent Cause:
The cause of P.his event has not been determined as of this' date, as the event has not reoccurred.
- 9. Analysis of occurrence:
- l This event had no safety implications as the high pressure injection pumps and the bor9ted water storage tank were available and operable.
- 10. Corrective Action:
An evaluation of this occurrence has been requested and corrective action will be taken pending results of the evaluation.
- 11. Failure Data:
This was not a repetitive occurrence.
