| Title | Licensee-Identified Violation |
| Description | Title 10 of the Code of Federal Regulations, Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, states, in part, that activities affecting quality shall be prescribed by procedures appropriate to the circumstances. Contrary to the above, a procedure for an activity affecting quality was not appropriate to the circumstances. Specifically, as of May 6, 2013, Procedure MPE GK-004 GK Unit Preparation for Work, Revision 4, was inadequate to prevent over-tightening of the wing screws on the filter dryer assembly, in that the procedure did not specify how tight to leave the wing screws. This led to failure of the filter drier, pieces of which blocked the thermostatic expansion valves and overheated the Class 1E electrical equipment air conditioning chiller. Using Inspection Manual Chapter 609, Appendix A, Exhibit 2, Mitigating Systems Cornerstone screening questions, Section A, the finding was determined to be of very low safety significance (Green) because only one train of Class 1E electrical equipment was affected and room temperatures remained below maximum limits. This violation was entered into the licensees corrective action program as Condition Report 68818. |
