Title | |
Event Description | The following information was provided by the licensee via phone and email:
At 1305 CST, on November 15, 2024, it was determined that division 2 cables for the '12' emergency diesel generator start circuitry are routed through a division 1 area without adequate fire barrier separation. This condition is not bounded by existing design and licensing documents; however, it poses no impact to the health and safety of the public or plant personnel. A fire impairment and hourly fire watch have been established for the affected fire zones. Therefore, this event is being reported as an eight-hour, non-emergency notification per 10 CFR 50.72 (b)(3)(ii)(B). The NRC Resident Inspector has been notified. |
