| Title | Licensee-Identified Violation |
| Description | Technical Specification 5.7.2, High Radiation Areas with dose Rates Greater than 1.0 rem/hour at 30 Centimeters from the Radiation Source or from any Surface Penetrated by the Radiation, but less than 500 rads/hour at 1 Meter from the Radiation Source or from any Surface Penetrated by the Radiation, requires in part that, access to, and activities in, each area shall be controlled by means of a radiation work permit (RWP) or equivalent that includes specification of radiation dose rates in the immediate work area(s) and other appropriate radiation protection equipment and measures. Contrary to the above, on October 8, 2013, two licensee personnel went into areas of a locked high radiation area (LHRA), in which they were not briefed to enter and therefore, were not knowledgeable of the dose rates. Specifically, the two personnel were briefed under a radiation work permit on the scope of work, travel path, and dose rates in the travel path and work area in order to investigate a steam leak on a component. After investigating the steam leak, these personnel decided to go to another location within the LHRA to ensure that another similar component did not have similar issues. This additional area was beyond the area that the personnel had been briefed to enter and this LHRA had elevated radiation levels subject to TS 5.7.2. The finding was determined to be of very low safety significance (Green) because it was not an ALARA planning issue, there was no overexposure nor potential for overexposure, and the licensees ability to assess dose was not compromised. The licensee documented the issue in CR 01910625, and issued a departmental human performance clock reset to re-emphasize the requirements for LHRA entries at the station. |
