Finding

Title

Safety Injection Refueling Water Tank Evaluation of Corrosion

Description

After reviewing CR-PLP-2012-4451, the inspectors were concerned the associated aging effects of the accumulated water were not properly managed because the condition of the affected annulus region was not evaluated by the licensee. Specifically, the accumulated water beneath the floor of the SIRW tank created an environment that could promote corrosion of the tank floor, and this condition does not appear to be formally evaluated. Also, the potential for corrosion could be exacerbated by concrete-aluminum interaction. The inspectors required more information to determine whether this issue constituted a finding of significance. This issue is considered an unresolved item pending further NRC review of the licensees actions.
