| Title | Licensee-Identified Violation |
| Description | The following violation of very low safety significance (Green) was identified by the licensee and is a violation of NRC requirements which meet the criteria of Section VI of the NRC Enforcement Policy, NUREG-1600, for being dispositioned as noncited violations. Technical Specification 5.7.2 requires the licensee to control access to a locked-high radiation area. A locked-high radiation area is defined as a high radiation area with dose rates greater than 1.0 rem per hour at 30 centimeters from the radiation source or from any surface penetrated by the radiation, but less than 500 rads per hour at 1 meter from the radiation source. Contrary to the above, on November 9, 2009, the reactor vessel head was moved from the head stand to the reactor cavity creating an uncontrolled locked-high radiation area. Procedure RPP 02-105, RWP, requires continuous health physics coverage for locked-high radiation areas. Specifically, a head area maintenance crew held a 2-minute safety brief which included health physics. After the safety brief, it was understood by the maintenance crew that all personnel were ready to commence the reactor head lift. However, after the 2-minute drill was completed, health physics personnel left the area to assist other crew personnel with dress out prior to entering the cavity. The remaining crew commenced to lift the reactor vessel head from the reactor headstand area to the reactor cavity without ensuring health physics technicians were present at the headstand area to provide locked-high radiation area coverage and surveys as required per Procedure RPP 02-105. The inspectors determined this finding to be of very low safety significance because: (1) it did not involve ALARA planning and controls, (2) there was no overexposure, (3) there was no substantial potential for an overexposure, and (4) the ability to assess dose was not compromised. This issue was entered into the licensee\'s corrective action program as Condition Report 00021703. |
