LER 315/2012-002-00: "Unit 1 Exceeded Technical Specification Time Limit to Shutdown." By letter dated September 14, 2012, Indiana Michigan Power (I&M), the licensee for Donald C. Cook Nuclear Plant (CNP), submitted LER 315/2012-002-00, "Unit 1 Exceeded Technical Specification Time Limit to Shutdown." At that time, CNP understood that the location of the wiring failure (failed wiring splice) affected the actuation function (Engineered Safety Features Actuation System) rather than the component (Steam Generator Stop Valve).Based on additional investigation, CNP has determined that the wiring failure instead affected the component rather than the actuating function.
"Unit 1 Exceeded Technical Specification Time Limit to Shutdown."
Consequently, the incorrect Technical Specification (TS) action statement for TS 3.3.2 was entered instead of TS 3.7.2. Repairs were completed in a time-frame such that Unit 1 would not have exceeded the TS 3.7.2 time limit to shutdown.
