| Title | Failure to Control a High Radiation Area with Dose Rates Greater Than 1000 Millirem Per Hour at 30 Centimeters |
| Description | The inspectors identified a non-cited violation of Technical Specification 5.7.2 for the failure to control a high radiation area with dose rates greater than 1000 millirem per hour at 30 centimeters. Specifically, equipment boxes placed adjacent to high radiation area barrier fencing in the reactor building 471 elevation, which created a natural ladder into the area, resulted in an uncontrolled entryway to a high radiation area with dose rates greater than 2500 millirem per hour. Once informed, the licensee immediately removed the equipment boxes from the barrier and added signage that restricted the placement of any items adjacent to the fencing forming the high radiation area barrier. This issue was documented in the licensees corrective action program as Action Request AR 00355646. The failure to properly control and barricade an entryway to a locked high radiation area in the reactor building, 471' elevation, was a performance deficiency. The performance deficiency was more than minor because it was associated with the program and process (exposure control) attribute of the Occupational Radiation Safety Cornerstone and adversely affected the cornerstone objective to ensure the adequate protection of the worker health and safety from exposure to radiation from radioactive material. Using NRC Inspection Manual Chapter 0609, Appendix C, "Occupational Radiation Safety Significance Determination Process, the inspectors determined that the finding had very low safety significance (Green) because the finding was not an as low as reasonably achievable planning or work control issue, there was no overexposure or potential for an overexposure, and the licensee's ability to assess dose was not compromised. The finding had a cross- cutting aspect in the area of Human Performance, Field Presence, because leaders were not commonly seen in the work areas of the plant observing, coaching, and reinforcing standards and expectations, resulting in a lack of oversight of work activities, to include contractors and supplemental personnel (H.2). |
