SUPPORTING CALCULATIONS FOR FINAL SIGNIFICANCE DETERMINATION OF WHITE FINDING FOR EDWIN I. HATCH NUCLEAR PLANT UNIT 2

Dear Mr. Ajluni:

During our telephone conversation on May 13, 2010, you requested the NRC forward the supporting calculations for the final significance determination of the White finding discussed in NRC Inspection Report No. 05000366/2009006, dated May 12, 2010 (ML101330476). The inspection finding was assessed using the NRCs Significance Determination Process (SDP).

The finding involved the failure to satisfy the requirements of Technical Specification (TS) 5.4, Procedures, to establish and perform preventive maintenance activities to replace electrolytic capacitors prior to their failure.

SNC requested in its March 19, 2010, response that the NRC re-evaluate the safety significance of the finding considering additional information provided in the response. In SNCs view this approach would take into account the real-world operational response to the event. After considering the information developed during the inspection and the additional information provided in SNCs written response, the NRC concluded that the finding should be characterized as a White finding, i.e., a finding with low to moderate safety significance which will require additional NRC inspection. The SDP calculations that supported the bases for the NRCs final significance determinations are attached as Enclosure 1.

Sincerely,

/RA/

Scott M. Shaeffer, Chief Reactor Projects Branch 2 Division of Reactor Projects Docket No.: 50-366 License No.: NPF-5
