Title | Inadequate Work Planning Control Relative to Regenerative Heat Exchanger Permanent Shielding Modification That Resulted in Additional Unplanned Collective Exposure |
Description | A Green self-revealing finding was identified because Entergy personnel did not adequately plan and control work activities related to a regenerative heat exchanger permanent shielding modification in accordance with radiation work permit (RWP) 20102537 , 2R19 Permanent Regen Hx Shielding. Specifically, Entergy personnel did not perform walkdowns to support modification package planning and provided limited field supervision which resulted in significant unplanned collective exposure (17.189 person-rem compared to a revised work activity estimate of 8.000 person-rem). This issue was entered into Entergy\'s CAP as CR-IP2-2010-02817. The finding is more than minor because it is associated with the program and process attribute of the Occupational Radiation Safety cornerstone and affected the cornerstone objective of ensuring the adequate protection of the worker health and safety from exposure to radiation from radioactive material during routine reactor operations. Additionally, this finding is similar to the more than minor example 6.j provided in IMC 0612, Power Reactor Inspection Reports, Appendix E, Examples of Minor lssues, because it involves an actual collective exposure greater than 5 person-rem and exceeded the planned, intended dose by more than 50%. Using IMC 0609, Appendix C, Occupational Radiation Safety Significance Determination Process, the finding was determined to have very low safety significance (Green) because the finding involved an as low as reasonably achievable (ALARA) planning issue and the 3-year rolling average collective dose history was less than 135 person-rem (52.261 person-rem average annual exposure for 2Q07-2Q09). The finding has a cross-cutting aspect in the area of human performance associated with the work control attribute because Entergy\'s planned work activities did not adequately ncorporate the job site interferences and their resolution in accordance with radiological safety |
