| Title | Items Relied on for Safety Not Operable |
| Event Description | It was determined at 1:30PM today (3/28/14) that one of the Items Relied on for Safety (IROFS) associated with the Dry Conversion Process recycle operation was inoperable. Although the second IROFS preventing moderation intrusion to the recycle container continued to operate within its allowable parameters, it alone was not sufficient to meet performance requirements.
The affected equipment has been shut down and at no time was an unsafe condition present. While this did not result in an unsafe condition, the event is being reported pursuant with the reporting requirements of 10CFR70 Appendix A (b)(2) within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of discovery. Additional corrective actions, extent of condition, and the cause of the failure are being determined. The licensee will notify NRC Region 2, State of North Carolina Radiation Protection, and New Hanover County Emergency Management.
After further review, it was determined, at approximately 1125 EDT on 3/31/2014, that the second IROFS [mentioned in the initial report] was not reliable to meet performance requirements. As a result, the report is amended as follows: The second IROFS preventing significant moderator intrusion to the recycle container was available, but its reliability could not be confirmed. The control continued to limit significant moderator intrusion and an unsafe condition did not exist. The remaining IROFS was not sufficient to meet performance requirements. As a result, the event report is being conservatively amended pursuant with the reporting requirements of 10CFR70 Appendix A (a)(4) within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> of discovery. The IROFS that was inoperable in the initial report was a process flow moisture probe. The second IROFS that was believed to be available in the initial report but later determined to not be reliable was a set of process control valves used to prevent moderation intrusion to the recycle container. The licensee will notify NRC Region 2, State of North Carolina Radiation Protection, and New Hanover County Emergency Management. Notified R2DO (Sykes) and NMSS EO (Rahimi) |
