| Title | Violation of Spent Fuel Handling Conditions |
| Event Description | This report is being made pursuant to a reporting requirement specified in Certificate of Compliance Number 1015, Appendix B2.1, which states that if any fuel specification or loading conditions of this section are violated that the affected fuel assemblies be placed in a safe condition; that the NRC Operations Center be notified within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> and that a special report be submitted within 30 days.
On 12/12/2005, fuel handlers were loading a NAC-UMS canister with spent fuel assemblies from the McGuire Unit Two fuel pool. As the fuel handlers were attempting to retrieve a fuel assembly from pool location PP-34, they inadvertently picked assembly Z50 from pool location RR-34. Once retrieved, the assembly was transferred to the canister where it was lowered into the canister. As the assembly was being lowered into the canister, a camera operator noticed that the fuel ID did not match the one specified in the loading procedures. The assembly was never disengaged from the grappling tool used to move it to the canister. From a fuel specification perspective, the initial enrichment was 3.636 weight percent U-235, the final burnup was 40,254 MWD, and the discharge date was 2/22/2002. At this time, the decay heat for this assembly has been conservatively determined to be greater than the decay heat allowed per assembly. The fuel specifications not being met for this condition were minimal cooling time of five years (Table B2-4) and the allowable decay heat per assembly (Table B2-1). Immediate corrective actions included returning the fuel assembly to its original storage location in the fuel pool. The licensee notified the NRC Resident Inspector. |
