Title	Steam Propagation Door Inoperable
Event Description	The following information was provided by the licensee via email and phone: At 2005 EDT on 9/17/2024, it was discovered that steam propagation door DRCB/501 would not latch properly; thus making the door inoperable. Door DRCB/501 is required as a steam propagation barrier to protect both trains of engineered safety feature equipment from effects of a postulated steam line break. Due to this inoperability, the plant was in a condition that could have prevented the fulfillment of a safety function; therefore, this condition is being reported as an eight-hour, non-emergency notification per 10 CFR 50.72(b)(3)(v). There was no impact on the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified. Steam propagation door DRCB/501 was repaired and maintained in the closed and latched position at 2032 EDT on 9/17/2024.
