"The plant is in a safe configuration.
"On December 4, 2022 at 0901 MST, water was discovered on the floor of the Liquid Effluent Collection and Transfer System (LECTS) room. A pump had catastrophically failed and resulted in leakage of 170 L of contaminated water from slab tank 3 to the inside of the slab tank berm. Upon arrival of the technician, the pump was stopped and the leak was isolated. Some of the water, estimated to be 10 L, leaked out of the berm. Access to this area was restricted at approximately 1100 MST by roping the area off and posting as a contaminated area. Dose rate readings in the area were taken and found to be less than 1 mr/hr and had not increased from previous surveys performed prior to the spill. Urenco USA (UUSA) expects the area will remain posted until after 1100 MST on December, 5, 2022, therefore the reporting requirement in 10 CFR 70.50(b)(1) will be met. The spill is in the process of being cleaned up.
"This issue has been entered in UUSA's corrective action program as EV 158739."
