Title | Improper Controls for Electrical Test Equipement |
Description | The inspectors identified a noncited violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, for the failure of maintenance planning personnel to provide adequate work instructions to control the connection of electrical monitoring devices on operable plant equipment. Specifically, the work instructions failed to require verification and functional testing after installation and removal, compliance with seismic requirements, and controls to ensure removal within the allowed time limit for a temporary installation. This finding was entered into the licensees corrective action program as Nuclear Notification 200396106. The finding is greater than minor because the improper controls for installation of test equipment is associated with the design control attribute of the Mitigating Systems Cornerstone and adversely affects the associated cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Using the Manual Chapter 0609, Significance Determination Process, Phase 1 Worksheets, the finding is determined to have very low safety significance because the finding did not affect both trains of any single mitigating system or represent an actual loss of a safety function. The finding has a crosscutting aspect in the area of human performance associated with work practices because maintenance planning personnel failed to follow procedures to develop adequate work instructions for safety-related maintenance H.4(b) (Section 1R18) |
