EN Revision Text: ITEM RELIED ON FOR SAFETY (IROFS) INOPERABLE
The following information was provided by the licensee via email:
"The plant is in a safe configuration. Three construction vehicles, a front end loader, road grader and roller, were allowed within the Controlled Access Area [CAA] boundary without IROFS50b and IROFS50c being declared Operable.
"The Administrative Control IROFS require physical barriers to be placed around the building of concern. Barriers had been placed but the IROFS had not been declared Operable by a Shift Manager.
"The construction vehicles were removed from the CAA and UUSA [Urenco USA] is conservatively reporting this event as a 1-hour Report. This event has been entered in UUSA's corrective action program as EV 149740 and a causal investigation will be performed."
The licensee will notify NRC Region 2.
* * * RETRACTION ON 04/25/2022 AT 1206 EDT FROM BARRY LOVE TO OSSY FONT * * *
The following retraction was received from Urenco USA (UUSA) via telephone and email:
"The accident sequence was originally evaluated for UUSA being in a construction phase and the applicable IROFS were applied based on these construction conditions. The accident scenario has been re-evaluated based on probabilities with current site conditions and assessed that the initiating events would be `highly unlikely' or less than 1E-06 per year, and therefore `not credible.' IROFS50b/c would not be required to meet the performance criteria of 10 CFR 70.61 for the construction vehicles on this project.
"Based on the reassessment of the accident scenarios, UUSA is retracting event notification EN 55770.
"UUSA will be notifying Region 2.
"EN 55802 is not being retracted."
