The following information was provided by the licensee via email:

"The plant is in a safe configuration. NRC Region II re-exited an inspection on April 26, 2022 from an inspection which was conducted March 21st through the 24th. During this exit, an event was reclassified as a Non-Cited Violation for failure to report an event. As a result, UUSA [Urenco-USA] is reporting this event as a 24-hour Report per the NRC's inspection.

"On February 28, 2022, water was discovered on the floor of the Liquid Effluent Collection and Transfer System (LECTS) room. The water was leaking from the slab tanks berm into the non-Radiological Controlled Area floor. The area was conservatively and promptly roped off and signage was posted. Radiological readings in the area were taken and found to be less than background and the the spill was cleaned up that day.

"Historical issues are being reviewed and will be added to this notification per the NRC's position shared with UUSA.

"This issue has been entered in UUSA's corrective action program as EV 149668 and 149975."
