Title

Licensee-Identified Violation

Description

Violation of TS 5.4.1, \'Procedures\' for not properly calibrating the Unit 1 power range nuclear instrument channel N41 and returning it to an operable status following I&C subsequent to the post-outage maintenance on November 4. The instrument was not calibrated properly due to mis-direction on which portion of the procedure to perform. The reactivity senior operator stationed at-the-controls quickly recognized the degraded instrument and alerted the crew. The licensee documented this issue in CR 10-85405. The violation is not greater than green because only one channel was affected for a short period of time.
