EN Revision Text: TECHNICAL SUPPORT CENTER DEGRADED DUE TO SUPPLY FAN BELT FAILURE
"This is an eight-hour, non-emergency notification for a loss of Emergency Assessment Capability. This event is reportable in accordance with 10 CFR 50.72(b)(3)(xiii) because the Technical Support Center (TSC) Supply Fan belt had failed which affects the functionality of an emergency response facility.
"Corrective maintenance activities are being performed on January 29, 2021 to the TSC HVAC [heating, ventilation, and air conditioning system]. The work includes replacing the failed belt and restarting the TSC Supply Fan. The work duration is approximately 12 hours.
"If an emergency is declared requiring TSC activation during this period, the TSC will be staffed and activated using existing emergency planning procedures unless the TSC becomes uninhabitable due to ambient temperature, radiological, or other conditions. If relocation of the TSC becomes necessary, the Emergency Director will relocate the TSC staff to an alternate location in accordance with applicable site procedures. The Emergency Response Organization team has been notified of the maintenance and the possible need to relocate during an emergency.
"There was no impact on the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified."
The licensee will be notifying the Illinois Emergency Management Agency.

EN Revision Text: AGREEMENT STATE REPORT - DISCONNECTED RADIOGRAPHY SOURCE
The following was received from the Texas Department of State Health Services (the Agency) via email:
"On January 29, 2021, the Agency was notified by the licensee's radiation safety officer (RSO) that on January 28, 2021, at 1730 [CST], one of their crews had experienced a source disconnect. The crew was using a Sentry model 330 device containing a 39.5 curie cobalt-60 source. The RSO stated the crew had completed work in one area and moved to a new location. After completing the first shot at the new location, the radiographers could not get the source to lock in the shielded position. The radiographers also noted elevated dose rates. The radiographers decided at this point that the source had disconnected. The radiographers contacted the site RSO who contacted the licensee RSO. The licensee contacted the device manufacturer who responded to the site. The manufacturer was able to retrieve the source by 0330 on January 29, 2021. An inspection of the equipment found that the drive cable connector had separated from the drive cable creating the disconnect. The RSO stated the drive unit was fairly new and did not show any signs of damage or rust. The manufacturer will inspect the drive unit to determine the cause of the disconnect. The RSO stated he was sending the dosimetry for his personnel to the processor for reading. No over exposures occurred during this event. Additional information will be provided as it is received in accordance with SA-300."
