| Title | Degradation of Safety Equipment |
| Event Description | It was discovered at approximately 1700 EDT on 6/19/2012 that the moderation control in the gadolinia pellet press operation had been degraded. An operator error allowed a can containing approximately 14 kg of uranium powder to be processed without the required material move transaction, a process control that ensures the container and material type are allowed at the designated location.
This resulted in a temporary degraded item relied on for safety (IROFS) condition involving a criticality control. The press moderation control is one of four IROFS to prevent a criticality accident. The gadolinia press station material control system functioned as designed and prompted the operator of an error. The other criticality controls on geometry were maintained at all times. At no time was an unsafe condition present. The gadolinia pellet press operation has been shut down and additional corrective actions, extent of condition, and extent of cause are being evaluated. This event is being conservatively reported pursuant to 10 CFR 70, Appendix A (b) (2).
On 6/20/12, GNF-A conservatively made a 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> event notification (EN 48038) due to a single missed Fuel Business System (FBS) transaction on 6/19/12 at the gadolinia press operation. After further review of the identified condition, it has been determined to be not reportable to NRC and the event notification can be retracted. Notified R2DO (Blamey) and NMSS EO (Silva). |
