Title	Loss of Power to Irradiator
Event Description	The following was received from the State of Texas (The Agency) via email: On March 27, 2021 at approximately 1021 [CDT], the licensee reported that on March 26, 2021, at approximately 1800 [MDT], their facility in El Paso, Texas, experienced the loss of an electrical breaker which resulted in loss of power to their irradiator, irradiator control system, and equipment room. The source racks immediately descended to the fully shielded position verified by the licensee. There was no exposure to any employee during this event. The access control radiation monitor was not operable due to power loss. The irradiator entry door, as designed, remained locked and unable to be opened. The building security system and security access alarm remained in full operation and the facility was manned. Product entry and exit portals were secured. The pool water circulation stopped due to the power loss and the radiation monitor that monitors the pool water for contamination from leaking sources also stopped working. The deionization monitor had been working properly until the time of the power loss and no levels above background had been detected. An authorized employee was scheduled to collect a water sample from the pool to be analyzed. The electrical breaker was replaced, all systems tested, and the irradiator resumed full operation by 1700 [MDT] on March 27, 2021. The irradiator is a Nordion Model 8900. Texas Incident Number has not yet been assigned.
