| Title | Failure to Post a High Radiation Area |
| Description | A Green self-revealing NCV of TS 5.7.1 was identified for the failure to post a high radiation area (HRA). Specifically, on September 25, 2014, the licensee failed to post th
Unit 2 high pressure coolant injection (HPCI) pump room as a HRA during a HPCI pump run in which maximum dose rates increased to 900 mrem per hour at 30 cm. As a result, an individual entered the area without knowledge of the changing radiological conditions and received a dose rate alarm. In response, the licensee immediately shut down the HPCI pump, performed a human performance review board, posted the area as a HRA, and surveyed the affected areas. The licensee entered this issue into the CAP as NCR 710281. The failure to post a high radiation area with dose rates greater than 100 mrem per hour is a performance deficiency. The performance deficiency was more than minor because it was associated with the Occupational Radiation Safety Cornerstone attribute of program and process (exposure control) and adversely affected the cornerstone objective to ensure the adequate protection of worker health and safety from exposure to radiation from radioactive material during routine civilian nuclear reactor operation. Failure to inform workers of radiological conditions through the use of postings could lead to unintended exposures. The Occupational Radiation Safety Cornerstone was affected; therefore, the inspectors used Manual Chapter 0609, Appendix C, Occupational Radiation Safety Significance Determination Process, dated August 19, 2008, to determine the significance of the violation. The violation had very low safety significance (Green) because: (1) it was not an as low as is reasonably achievable finding, (2) there was no overexposure, (3) there was no substantial potential for an overexposure, and (4) the ability to assess dose was not compromised. The finding has a cross-cutting aspect in the area of human performance, associated with the teamwork attribute, because individuals and work groups failed to communicate and coordinate their activities within and across organizational boundaries to ensure nuclear safety is maintained and post the HPCI room as a high radiation area.
