A self-revealing, NCV of TS 6.12.1.b occur … A self-revealing, NCV of TS 6.12.1.b occurred when a worker entered a high radiation area (HRA) without being made knowledgeable of dose rates in the area prior to entry. Specifically, on November 10, 2015, a worker performing a plant surveillance under radiation work permit (RWP) 15-004, Clearance Tags, Surveillances and Inspections, climbed into overhead in the Unit 2 Pipe Penetration room and received an electronic dosimeter (ED) dose rate alarm. The licensee entered this issue into the CAP as AR 02090225 and took immediate corrective actions which included restricting the operators access to the radiological control area (RCA), performing followup surveys and convening a human performance review board to examine causal factors for the purpose of determining corrective actions. This PD was determined to be more than minor because it is associated with the Occupational Radiation Safety Cornerstone attribute of Human Performance and adversely affects the cornerstone objective of ensuring adequate protection of worker health and safety from exposure to radiation from radioactive material during routine civilian nuclear reactor operation. Workers permitted entry into HRAs with inadequate knowledge of current radiological conditions could receive unintended occupational exposures. The finding was evaluated using the Occupational Radiation Safety SDP. The finding was not related to as low as reasonably achievable (ALARA) planning, nor did it involve an overexposure or substantial potential for overexposure, and the ability to assess dose was not compromised. Therefore, the inspectors determined the finding to be of very low safety significance (Green). The inspectors noted that the operator responded properly to the ED dose rate alarm thereby limiting his potential for unintended exposure. This finding involved the cross cutting aspect of (H8) procedure adherence because the individual understood the RWP requirements but failed to comply with them.quirements but failed to comply with them. +
