| Title | Licensee-Identified Violation |
| Description | A violation of Limerick Unit 2 Technical Specification 6.12.2, which states, in part: For High Radiation Areas with dose rates greater than 1.0 rem/hr (at 30 cm), but less than 500 rad/hr (at 1 meter) shall be controlled as follows: a. Each accessible entryway to such an area shall be conspicuously posted as a High Radiation Area and shall be provided with a locked door, gate, or guard that prevents unauthorized entry. RP-AA-460, Controls for High and Locked High Radiation Areas, implements this requirement. Attachment 6 of RP-AA-460, states, in part: 1). Item 1: REMAIN outside the assigned area and MAINTAIN direct line-ofsight surveillance of the access to the LHRA... 2). Item 7: Prior to transferring Access Control Guard responsibilities, verify that the individual has a signed copy of this form (for a non-RP relief individual) and that the new Access Control Guard is aware of the conditions of the work area. Contrary to the above, on April 14, 2011, a technician filling the role of a LHRA access control guard for the LHRA associated with the Unit 2 drywell equipment hatch, left the post unguarded for several minutes. An OI investigation determined that the technicians actions did not constitute deliberate misconduct; however, the NRC confirmed that the TS had been violated. The violation is similar to IMC 0612, Appendix E, example 6g which states an HRA access not controlled in accordance with procedures is more than minor if a radiation area of greater than 100mrem/hr at 30 cm actually existed in the area. This violation is of very low safety significance since, there is no evidence anyone attempt to gain access while the access point was unguarded was short, the duration of time the access was unguarded, and the presence of cameras which allowed for remote monitoring. Exelon enter the issue into their CR process as IR 1202506. |
