| Title | Failure to Maintain Radiation Exposure ALARA During RF-16 |
| Description | A finding of very low safety significance was self-revealed due to the licensee having unplanned and unintended occupational collective radiation dose because of deficiencies in the licensees Radiological Work Planning and Work Control Program. Specifically, the licensee failed to properly incorporate As-Low-As-Is-Reasonably-Achievable (ALARA) strategies and insights while planning and executing work activities on Reactor Building Level 5 (RB-5) during the refueling outage RF-16. Radiation Work Permit (RWP) 145002 was written to perform refuel activities on RB-5, including core alterations, bridge repair, local power range monitor (LPRM) replacement, fuel sipping, and radiation protection support. The initial dose estimate for this work was 3.710 person-rem. However, 15.329 actual person-rem of dose was received. The licensee performed a Job Progress ALARA Review where it became apparent to the licensee that the percentage of work completed was not tracking with original dose estimates. The licensee identified some of the reasons for the increased dose for the work activity included equipment reliability, work quality, and human performance errors. The licensee has entered this issue into its corrective action program as Condition Assessment Resolution Document (CARD) 14-23433. The finding was more than minor because it was associated with the program and process attribute of the Occupation Radiation Safety Cornerstone. Additionally, this issue adversely affected the cornerstone objective of ensuring adequate protection of the worker health and safety from exposure to radiation from radioactive material during routine civilian nuclear reactor operation. Additionally, the finding is very similar to Manual Chapter 0612, Appendix E, Examples of Minor Issues, Example 6.i. This example provides guidance that an issue is not minor if the actual collective dose exceeded 5 person-rem and exceeded the planned intended dose by more than 50 percent. The licensees current collective 3-year rolling average was 65.077 person-rem (2011-2013). This is less than the 240 personrem/unit referenced within Manual Chapter 0609, Appendix C, Occupational Radiation Safety Significance Determination Process. The inspectors determined that this finding affected the cross-cutting area of human performance and the field presence aspect (H.2), in that leaders were not commonly seen in the work areas of the plant observing, coaching, and reinforcing standards and expectations. Deviations from standards and expectations were not corrected promptly. Senior managers did not ensure supervisory an
management oversight of work activities, including contractors and supplemental personnel. |
