EN Revision Text: INSTANCES OF UNANALYZED CONDITIONS
The following information was provided by the licensee via email:
"As part of the extent of condition review for EN55770, [Urenco USA] UUSA identified historical instances where construction vehicles may have been allowed near buildings of concern and our process failed to identify if controls needed to be established for the activities planned. The hazards associated with those construction vehicles were not properly analyzed. UUSA failed to properly document and require controls and, during those times, available [Item Relied On For Safety] IROFS appear to be insufficient to meet the performance requirements in [10 CFR] 70.61.
"No unanalyzed vehicles presently exist near buildings of concern. This event has been entered in UUSA's corrective action program as EV 149990. The plant is in a safe configuration."
The licensee notified NRC Region 2 personnel.

EN Revision Text: AGREEMENT STATE REPORT - SOURCE NOT SECURE WITHIN GAUGE
The following information was received from the Texas Department of State Health Services (the Agency) via E-mail:
"On April 12, 2022, the Agency received an email from a licensee regarding an Am-241 source that was no longer within the source holder of a Troxler Model 3430 (source assay date 9/29/1997 and serial 28367). The source capsule, source holder, and source cap were all loose within the gauge. This was the first notification to this Agency of this issue. The licensee reported that on March 25, 2022, a licensee technician reported measurement issues with this device. A survey of the device did not find any elevated readings. The device was pulled from service and inspected on March 30, 2022, at which point the loose components were discovered. This licensee had experience with this issue before (see EN 55774) and repaired the assembly using Loctite.
Licensee reports the source is not leaking and is secured within the source holder. Investigation is ongoing and additional information will be provided per SA-300."
