| Title | Seismic Qualification of the Condensate Storage Tank and Related Flooding Barriers |
| Description | The inspectors identified an unresolved item (URI) associated with the wall and flooding barrier between the CST and the non-vital switchgear room because the seismic qualifications were not clearly defined. During the performance of TI 2515/183, the inspectors identified a potential deficiency associated with the seismic qualification of the CST, the flooding barriers between the CST and the vital switchgear room, and the ability to protect the related vital switchgear. 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 seismic qualification utility group (SQUG) methodology and complex calculations to justify operability of the equipment. The inspectors concluded that this issue is an URI pending a review of the related calculations, use of SQUG methodology, and a review of the Point Beach licensing basis for seismic qualifications (URI 05000266/2011003-02; 05000301/2011003-02, Seismic Qualification of the Condensate Storage Tank and Related Flooding Barriers). |
