| Title | |
| Description | The inspectors identified a finding associated with the licensees failure to adequately plan and control work activities associated with Alloy 600 ultrasonic examinations during Refueling Outage 19. Specifically, the inspectors concluded that, had the licensee appropriately evaluated the Alloy 600 pipe weld conditions/locations during the ALARA planning process and appropriately performed in-progress ALARA reviews, they could have reasonably planned for the full scope of work and provided a better estimate and/or adequately justified revising the estimate for the job. These failures to plan and control the job activities led to unplanned, unintended collective dose. The licensee evaluated the procedures used during this work, including their process for planning and estimating doses, and documented the issue in the corrective action program. The failure to adequately plan and control work activities associated with Alloy 600 ultrasonic examinations is a performance deficiency. This performance deficiency is more than minor because it is associated with the program and process attribute of the Occupational Radiation Safety cornerstone. It adversely affects the cornerstone objective to ensure adequate protection of the worker health and safety from exposure to radiation from radioactive material during routine civilian nuclear reactor operation. Specifically, it caused the collective radiation dose for the work to be greater than 5 man-rem and exceed the planned dose estimate by more than 50 percent. Using Inspection Manual Chapter 0609, Appendix C, Occupational Radiation Safety Significance Determination Process, dated August 19, 2008, the inspectors determined the finding has very low safety significance because: (1) it was associated with ALARA planning and (2) the licensees three-year rolling average collective dose of 121.7 man-rem was less than 135 man-rem. The finding has a Work Management cross-cutting aspect, associated with the Human Performance cross-cutting area, because the licensee did not adequately plan or control work activities such that nuclear safety is the overriding safety priority. Specifically, the ALARA plan did not reflect the time needed to complete the work activities, thus underestimating the dose requirements, and the administrative control of reviewing the work-in-progress at appropriate completion points failed. |
