Title	Irofs Surveillance Periodicity Error
Event Description	It was discovered that the calculation which determines the periodicity for performing the IROFSC22 [Item Relied On For Safety] surveillance contains an error. IROFSC22 is a mass balance enrichment control. It is unclear if the calculation error causes the surveillance periodicity to fall outside of the minimum time to achieve a safe mass. UUSA [Urenco USA] has since changed the IROFS surveillance to a more frequent periodicity which has been determined to be sufficient. Although no event has occurred and the IROFS remain sufficient to meet the performance requirements of 10CFR70.61, as a conservative measure, UUSA is reporting this condition due to the facility being in a state that is different from that analyzed in the Integrated Safety Analysis and in accordance with 10 CFR 70 Appendix A(b)(1) The plant is in a safe condition. The licensee will notify NRC Region 2 (Lopez).
