| Description | For Unit 1: As described in the Final Safety Analysis Report through Amendment 78 and as approved in the Safety Evaluation Report (NUREG-0797), and its supplements through Supplemental Safety Evaluation Report 24. 15 For Unit 2: As described in the Final Safety Analysis Report through Amendment 87 and as approved in the Safety Evaluation Report (NUREG-0797), and its supplements through Supplemental Safety Evaluation Report 27.
The Fire Protection Report was included as part of the licensees approved fire protection program for both units. The Fire Protection Report was included as part of the licensees Final Safety Evaluation Report for both units, and states, in part, that administrative control of the fire protection program is provided through station procedures to assure that the fire protection equipment/systems are operable and properly maintained. This includes periodic tests and inspections, compensatory measures concerning items which may be inoperable, and quality assurance audits. The program applies to fire protection equipment and systems that protect fire areas which contain safe shutdown equipment. Revision 30, Section IV-2.1.b.1.g of the Fire Protection Report required that at least once per 3 years the fire suppression water system be demonstrated operable by performing a flow test of the system in accordance with Chapter 5, Section 11 of the NFPA Fire Protection Handbook, 14th Edition. This section of the handbook directs the licensee to carefully choose test points and conduct tests in such a way that the available flow and pressure at high value or hazardous areas can be determined readily. Contrary to the above, prior to June 29, 2017, the licensee failed to implement all provisions of the approved fire protection program. Specifically, the licensee identified that Comanche Peak currently performs loop flow testing of the underground Fire Suppression Water System piping per Procedure FIR-PX-3200, Fire Suppression Loop Flow Test, Revision 3, which the licensee identified did not test portions of the underground loop that feed into the main power block buildings, which contain areas housing safety-related and important to safety equipment, and may not be in accordance with the methodology described in Chapter 5, Section 11 of the Fire Protection Handbook, 14th Edition, such that the available flow and pressure at high value or hazardous areas can be determined readily. The performance deficiency was more than minor because it was associated with the protection against external factors (fire) attribute of the Mitigating Systems cornerstone and adversely affected the Mitigating Systems cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The finding was screened in accordance with Inspection Manual Chapter 0609, Appendix F, dated September 20, 2013. The finding was determined to be of very low safety significance (Green) in Task 1.4.7, Fire Water Supply, Question A, because at least 50 percent of required fire water capacity (flow at required pressure) will still be available as evidenced by successful testing of the main transformer suppression systems. The violation was entered into the licensees corrective action program as Condition Report CR-2017-007536. |
