| Title | Licensee-Identified Violation |
| Description | Technical Specification 5.4.1 requires, in part, that written procedures shall be established, implemented, and maintained covering the activities specified in Regulatory Guide 1.33, Quality Assurance Program Requirements (Operation), Revision 2. Regulatory Guide 1.33, Appendix A, Section 9a, requires, in part, that procedures performed for maintenance be properly preplanned and performed in accordance with instructions. Contrary to the above, on May 8, 2008, during the installation of the reactor vessel head, licensee workers failed to implement Procedure 7.4.4.1, Reactor Pressure Vessel Head Installation, Revision 25, steps 4.32.1 through 4.43.4 for tensioning of the studs. Consequently, the reactor head stud tensioning had to be reworked and repeated resulting in an additional six person-rem of unplanned radiation exposures. Additionally, other planning issues and poor worker performance resulted in Job Package 2008-005, Refuel Floor Work, to exceed the initial dose estimate of 19.862 person-rem by approximately 80 percent, and accumulated a total of 35.08 person-rem. The issue has been entered into the licensees corrective action program as Condition Report CR-CNS-2008-3585. The inspectors determined the finding had very low safety significance because, although the finding did involve ALARA work planning and controls, the licensees latest official 3-year rolling average collective dose was less than 240 person-rem |
