| Title | RHR Pump Operability with Tanks in Auxiliary Building Not Seismically Qualified |
| Description | The inspectors identified an URI for the operability of the RHR pumps because the seismic qualifications of certain water storage tanks in the auxiliary building were not clearly defined. During the performance of TI 2515/183 the inspectors identified a potential deficiency associated with the seismic qualification of the RHR pumps because several tanks in auxiliary building were not seismically qualified. The inspectors, in consultation with a Region III civil engineer, performed an evaluation of the licensees determination of operability for the issue. The inspectors found that the licensee utilized various elements of SQUG methodology and complex calculations to justify operability of the equipment. The inspectors concluded that this issue is unresolved pending a review of the related calculations, use of SQUG methodology, and a review of the Point Beach licensing basis for seismic qualifications (URI 05000266/2011003-03; 05000301/2011003-03, RHR Pump Operability with Tanks in Auxiliary Building Not Seismically Qualified). |
