PLANT ENTERED A NOUE DUE TO BOTH EMERGENCY DIESEL GENERATORS BEING DECLARED INOPERABLE
The licensee declared an unusual event at 0026 CST due to both Emergency Diesel Generators being inoperable resulting in the loss of on-site power capability. At 0017 the "B" Diesel Generator failed to start during an attempt to verify operability as required by TS 3.7.b.2 since the "A" Diesel Generator was out of service for maintenance. They are investigating the cause for the no start of the "B" Diesel Generator. The plant has 6 hrs to be in hot standby and the following 6 hrs to hot shutdown.
The NRC Resident Inspector will be notified. State and local agencies were notified and there may be a press release.

"Unusual Event Termination
"At 0624 the B emergency diesel generator was returned to service. This exited the condition in EPIP-AD-02, Emergency Class Determination," requiring declaration of an Unusual Event. At 0656 the Unusual Event was terminated."
The licensee replaced a faulty speed sensing relay at the "B" EDG relay panel and was subsequently able to re-start the diesel from the control room. The unit is currently stable, holding power at 9.3% and all systems are functioning as required. The licensee notified the NRC Resident Inspector, the State and local authorities. A media/press release was issued by the licensee.
Notified R3DO(Kozak), NRR EO (Johnson), DIRO (Hiland) and FEMA (Caldwell).
