ENS 56915 | Davis Besse | 5 January 2024 15:40:00 | Emergency Ventilation Systems Inoperable | The following information was provided by the licensee via phone and email:
At approximately 1111 EST on 01/05/2024, a mechanical penetration room door was discovered unlatched. Based on security badge history, the door was last opened at 1040 EST. The unlatched door resulted in both trains of the station emergency ventilation system being inoperable due to being unable to maintain the shield building negative pressure area. With both trains simultaneously inoperable, this condition is being reported as an eight-hour, non-emergency notification per 10 CFR 50.72(b)(3)(v). The door was closed and verified latched upon discovery to restore the systems to an operable status.
There was no impact on the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified.
- * * RETRACTION ON 1/17/24 AT 1400 EST FROM CHRIS HOTZ TO ADAM KOZIOL * * *
The station emergency ventilation system (EVS) was tested with the mechanical penetration room door unlatched. The test results showed that the station EVS attained the required negative pressure in the shield building within the time required by the Technical Specifications. Therefore, the station EVS remained operable with the door unlatched, and this issue did not prevent the system from fulfilling its safety function to control the release of radioactive material and mitigate the consequences of an accident.
The NRC Resident Inspector has been notified.
