Report No.: 50-302/77-77 2.
Facility: Crystal River Unit #3
- 3. Report Date: 2 August 1977
- 4. Occurrence Date: 9-10 July 1977
- 5. Identification of Ce.urrence:
Cheuical addition pumps CAP-3A and 3B inoperable contrary to Technical Specifications 3.1.2.2.
- 6. Conditions Prior to occurrence:
Mode 1 power operation.
- 7. Description of Occurrence:
At 0810 on 9 July 1977 and 0815,10 July 1977 preparing to add boric acid to the nakeup tank, chemical addition pumps 3A or 3B would not deliver boric acid to the tank. The -
pumps were determined to be airbound and were vented on each occurrence, restoring operability.
- 8. Designation of Apparent Cause:
The system was thoroughly checked and no immediate cause for the pumps being airbound was iound.
- 9. Analysis of Occurrence:
This event had no safety significance as the high pressure injection pumps and the
, borated water storage tank were available and operable.
- 10. Corrective Action:
Vent valves were installed on each pump and appear to have been effective in precluding recurrence as the event has not repeated.
- 11. Failure Data:
These two occasions constituted the second occurrence of this event. Previous occurrence reported as LER 77-53.
