| Title | Entry into an Area with Unknown Dose Rates |
| Description | The inspectors reviewed a finding of very low safety significance (Green) with an associated NCV of TS 5.7.1, which was self-revealed when a worker received a dose rate alarm from an electronic dosimeter when he entered an area with an unknown dose rate. The inspectors determined that the performance deficiency was more than minor in accordance with IMC 0612, Power Reactor Inspection Reports, Appendix B, Issue Screening. Specifically, the performance deficiency impacted the program and process attribute of the Occupational Radiation Safety Cornerstone, and adversely affected the cornerstone objective of ensuring adequate protection of workers health and safety from exposure to radiation, in that, the unauthorized entry into an area where the dose rates were unknown removed a barrier intended to prevent the worker from receiving unexpected dose. The inspectors concluded that this activity was within the licensees ability to foresee and should have been prevented. This finding was not subject to traditional enforcement since the incident did not result in a significant safety consequence, did not impact the NRCs ability to perform its regulatory function, and was not willful. The finding was assessed using the Occupational Radiation Safety Significance Determination Process, and was determined to be of very low safety significance (Green) because the problem was not an ALARA planning issue, there were no overexposures nor substantial potential for overexposures, and the licensees ability to assess dose was not compromised. The inspectors concluded that the issue involved a cross-cutting component in the human performance area of teamwork due to communication issues that were reported by the licensee during the pre-job brief for the job [H.4]. |
