Title	Technical Specifications Violation
Event Description	The following information was provided by the licensee via phone and email: At approximately 1100 CST on December 15, 2023, the facility was discovered to be in violation of a Limiting Condition of Operation (LCO) according to Technical Specification 3.3.2.2, which requires that the static pressure measurement in the confinement exhaust system measure -0.1 inches of water or less during operation. It was discovered that this plant variable was not tied to the PANALARM trip for 'Building Pressure', nor was the sensor output value available in the control room to be checked by operators. The PANALARM trip for 'Building Pressure' was set to a different variable not related to the LCO required value. This condition has existed since 2006. The reactor was not in operation at the time of the discovery, and the situation creating this LCO violation is being corrected prior to the next reactor startup. The following additional information was obtained from the licensee in accordance with Headquarters Operations Officers Report Guidance: The issue was discovered by the vendor when a controller board was being replaced after damage from a power outage. * * RETRACTION ON 12/15/2024 AT 2233 EST FROM JERE JENKINS TO IAN HOWARD * * * The following information was provided by the licensee via email: This event report is hereby withdrawn. The reactor was not operated in contravention with the LCO. The confinement pressure was maintained. Notified NRR (Boyle) and NRR (Waugh)
