Title | Inadequate Work Planning for\'A\' Reactor Recirculation Pump Replacement |
Description | The inspectors identified a self-revealing finding that involved inadequate work planning relative to the \'A\' recirculation pump replacement work during refueling outage R19 that resulted in additional unplanned collective exposure (39.168 person-rem compared to a work activity estimate of 15.831 person-rem). The actual job site conditions were not adequately evaluated by Entergy staff for interferences and the support work was not coordinated to prevent additional unnecessary exposure and did not meet the Radiation Work Permit (RWP) No. 10-0518 planned dose execution for the work activity. This inadequate evaluation lead to as-found interferences that required removal and reinstallation, and insufficient outage schedule coordination that resulted in several scaffold interferences with other outage tasks that caused avoidable scaffold rework and in unintended exposure that could have been avoided by Entergy personnel. The finding was more than minor because it was associated with the Radiation Safety - Occupational Radiation Safety cornerstone attribute of program and process, and affected the cornerstone objective of protecting worker health and safety from exposure to radiation. Specifically, inadequate work planning resulted in unplanned, unintended collective exposure that was greater than 50 percent above the intended collective exposure and greater than five person-rem due to conditions that were reasonably within Entergy\'s ability to foresee and correct. The inspectors evaluated the finding using IMC 0609, Appendix C, Occupational Radiation Safety Significance Determination Process, and determined that the finding was of very low safety significance (Green) because the finding was due to As Low As Reasonably Achievable (ALARA) work control planning and the three year rolling average collective exposure at FitzPatrick was less than 240 person-rem (146.593 person rem for 2008-2010). The finding had a cross-cutting aspect in the area of Human Performance, work control, because Entergy\'s planned work activities did not adequately incorporate work site interferences or outage work coordination in the work control planning process |
