CERTIFICATE OF COMPLIANCE VIOLATION
The following information was provided by the licensee via phone and email:
On December 8, 2025, at 1424 EST, it was confirmed that a primary neutron source assembly (NSA) was loaded into a multi-purpose canister contrary to the requirements stated in the Certificate of Compliance (CoC, Renewed Amendment 11). Specifically, one primary NSA was loaded in the incorrect fuel storage location. Table 2.1-1 of the CoC requires fuel assemblies containing NSAs to be loaded in fuel storage locations 13, 14, 19, and/or 20. The primary NSA, however, was loaded into fuel storage location 32 in April, 2024. This condition is reportable in accordance with section 2.2 of the CoC.
It has been verified that the total heat load of the fuel cask remains bound by the requirements of the CoC. There are also no adverse impacts to criticality since the primary NSA is in the outer region of the fuel cask, which is more conservative than the inner region. All other NSAs were verified to be in their approved fuel storage locations. All offsite and occupational dose remain within regulatory limits.
This condition poses no impact to the health and safety of the public or plant personnel.
The NRC Resident Inspector has been notified.
