Finding

Title

LPCI Room Equipment EQ Qualification Deficiencies and Discrepancies

Description

The inspectors identified an unresolved item regarding the ability of the LPCI room safety-related equipment to perform its post-LOCA design safety function without LPCI room cooling. The inspectors noted that Dresden EQ binders concluded that safety-related equipment throughout the reactor building was adequately environmentally qualified for post-EPU post-LOCA conditions without the LPCI room coolers and the associated fans. The inspectors noted that the motor used in the EQ test was not identical to the motors installed at Dresden. The inspectors questioned whether the motor used in testing was acceptable. These issues are considered unresolved (URI 05000237/2008002-03 (DRS) URI 05000249/2008002-03 (DRS)) pending the inspectors review of the licensing basis
