| Title | Unusual Event - Loss of All Offsite Power |
| Event Description | The following information was provided by the licensee via phone and email:
At 0209 EST on 02/23/2026, with Hope Creek in Mode 1 at 100 percent power, the reactor automatically tripped due to a loss of offsite power. All emergency diesel generators (EDGs) started and loaded as expected to power vital buses. Operations responded and stabilized the plant in Mode 3. Reactor water level is being maintained via high pressure coolant injection (HPCI) and reactor core isolation cooling (RCIC). Reactor pressure is being maintained using safety relief valves (SRVs). Due to the reactor protection system actuation while critical, this event is being reported as a four-hour, non-emergency notification per 10 CFR 50.72(b)(2)(iv)(B). An Unusual Event (SU1.1) was declared at 0229 on 02/23/2026, due to a loss of offsite power to all vital buses for greater than 15 minutes. There was no impact on the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified, and all offsite notifications have been made. Notified DHS SWO, FEMA Operations Center, FEMA NWC, CISA Central Watch Officer, CWMD Watch Desk, DHS Nuclear SSA (email), DHS NRCC THD Desk (email).
