10 CFR 50.55a, Codes and Standards, requires that systems and components of boiling and pressurized water-cooled nuclear power reactors shall meet the requirements of the ASME Boiler and Pressure Vessel Code. Contrary to this, AmerGen did not perform an accelerated IST of the 1-1 service water pump in August 2008, as required by the ASME code when the pumps performance was evaluated to be in the alert range during its quarterly IST on June 19, 2008. The following quarterly IST on September 16, 2008 showed the pumps performance to be in the action range. The increased frequency testing was not performed because the work order to perform the testing was not properly coded in the work management system. AmerGen performed a technical evaluation and determined that the cause of the degradation in the pumps performance was due to a system degradation, specifically system leakage, and verified that the pump was operating satisfactorily and was not degraded. The violation was of very low safety significance because the deficiency was a qualification issue that did not result in the loss of operability of the system or component. The issue is described in corrective action program condition reports IR 820700 and CR 787909. Corrective actions involved AmerGen performing an extent of condition review on work orders involving surveillance testing and ISTs to ensure they were properly coded and scheduled correctly.
