Finding

Title

Licensee-Identified Violation

Description

License Condition 2.C.(1) states, in part, that the licensee is authorized to operate both units at reactor core power levels not to exceed 3586.6 megawatts thermal. Contrary to this, both units exceeded their license thermal power limits since original construction by approximately 0.5 percent. The licensee identified that the flow coefficient utilized in the reactor power calorimetric calculation was not conservative during a post-maintenance calibration of a new flow instrument. The finding was determined to have very low safety significance because it only involved the potential to affect the fuel barrier. The licensee entered this issue into the CAP as IR 1217236 and implemented the correct flow coefficients.
