| Title | Failure to Implement Maintenance Procedure for Control Room Air Conditioning System |
| Description | A self-revealing Green non-cited violation (NCV) of Hatch Unit 1 and Unit 2 Technical Specification 5.4, Procedures, was identified when the B main control room air conditioning condenser tripped on high discharge pressure due to an improperly adjusted water regulating valve. The licensee entered the condition into their corrective action program as CR 10217777 and adjusted the water regulating valve to the appropriate setpoint. Failure to adjust the water regulating valve in accordance with preventive maintenance procedure 52PM-Z41-002-1, Control Room Air Conditioning Maintenance, was a performance deficiency. The performance deficiency was more than minor because it associated with the Equipment Performance attribute of the Mitigating Systems Cornerstone and adversely affected the cornerstone objective in that the failure resulted in the inoperability of the B main control room air conditioner. The finding screened as Green because the loss of component function did not significantly affect the function of the train or system. The inspectors determined that this finding had a cross-cutting aspect in the Resources aspect of the Human Performance area, because the licensee did not ensure that procedures were available and adequate to support nuclear safety [H.1]. |
