| Description | Technical Specification 5.4.1.c requires the licensee to establish, implement, and maintain written procedures covering implementation of the fire protection program. Unit 1 Operating License Article 3, Condition F states that the licensee shall implement and maintain in effect all provisions of the approved fire protection program. The program requires, in part, periodic maintenance and testing necessary to maintain system operating condition and functionality. Contrary to the above, the licensee failed to implement written procedures that ensured the fire protection was maintained in accordance with the fire protection program. Specifically, the Unit 1 hydrogen seal oil deluge fire protection system was returned to service with a hose fitting installed in place of one required spray nozzle. A review of the maintenance procedure revealed that the procedure did not contain the number or location of fittings to be replaced after testing the system and relied on the technician to review drawings to determine the correct number and placement of nozzles. Further review of similar procedures used to maintain and test the fire protection system revealed the same vulnerability. Upon discovery, this issue was immediately documented in IR 1168144 and the fitting was replaced with the appropriate nozzle. This issue is more than minor because the performance deficiency, if left uncorrected, would have the potential to lead to a more significant safety concern during future maintenance activities in that the same deficiencies existed in procedures for fire protection systems that were required to support safe shutdown of the unit. The finding is of very low safety significance or Green because the spray nozzles provide overlapping coverage and the deluge system would have been able to perform its function. Therefore, the degradation rating for the deficiency is low; therefore, the finding is screened to Green in accordance with IMC 0609, Appendix F, Task 1.3.1 |
