| Title | Item Relied on for Safety (Irofs) Inoperable |
| Event Description | The following information was provided by the licensee via phone and email:
At approximately 2345 MDT, on 4/1/2024, it was observed that the physical boundary of IROFS10 had been opened while this boundary was being relied upon to perform its safety function. This initial report is being made as a 1-hour notification under Appendix A to 10 CFR70 (a)(4). The boundary (an isolation valve) was partially opened inadvertently by contact with adjacent equipment while performing operation of 1003 liquid sampling autoclave. The partially opened valve has been shut, restoring the IROFS10 boundary, and the autoclave has been placed in cooling mode. Out of conservatism, until an extent of condition can be performed, the 1004 autoclave which has a similar design has been taken out of service and placed in cooling mode as well. There has been no indication of leakage from any operating liquid sampling autoclave to the environment. The system and plant are in a stable condition. The following additional information was obtained from the licensee in accordance with Headquarters Operations Officers Report Guidance: The isolation valve was open less than 30 seconds and there was no exposures to personnel. The licensee will notify the NRC Region.
The potential leakage through the open boundary has been determined. The valve, if fully open, would not result in exceeding the 10 CFR 70.61 performance requirements. Thus, the 10 CFR 70 (a)(4) reporting requirement was not met, and this event notification is retracted. Notified R2DO (Miller) and NMSS Events Notification (email). |
