LOW LEVEL CONTAMINATION OF FUTURE PRODUCTION AREA
The following is a synopsis of a phone report received from Curium USPET LLC.
At 1907 EST on January 21, 2021, the Radiation Safety Officer (RSO) at the Curium USPET LLC facility in Noblesville, IN was notified that one hand/foot monitor was alarming. Upon investigation it was determined to be a valid alarm. The area was surveyed and revealed two small areas of Strontium-82 contamination, apparently transferred from shoe cover booties. The total contamination was 640 microCuries, all within the Future Production Area (10,450 sq. ft. area). Decontamination of the area was initiated and completed at 1630 EST on January 22, 2021. The three decontamination workers each received 0.4 mREM dose during the clean-up process. No contamination escaped the Future Production Area room. Source/cause of the contamination is being investigated.

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.
