| 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 meets the criteria of the NRC Enforcement Policy, for being dispositioned as a Non-Cited Violation. Technical Specification 5.7.1, High Radiation Area, requires posting and barricading of HRAs with dose rates not exceeding 1 Rem/hour at 30 centimeters from the radiation source or from any surface penetrated by the radiation. Contrary to this, on April 25, 2012, an unposted and unbarricaded HRA was identified by the licensee in the Unit 1 Reactor Building 80 elevation Reactor Water Clean-Up (RWCU) Precoat Tank area. During the previous shift, following a RWCU Back Wash Receiving Tank (BWRT) resin transfer drop to the Radwaste RWCU phase separators, a survey was performed and the area was downposted from HRA to RA. However, the survey failed to detect dose rates on the piping underneath the Unit 1 RWCU Precoat tank of 2.5 Rem/hour contact and 0.4 Rem/hour at 30 centimeters. The elevated dose rates were not found until a procedurally required follow-up survey was performed approximately 3.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> later by another HP technician. The technician took immediate corrective actions including posting and barricading the affected area. This finding was of very low safety significance (Green) because there was no substantial potential for overexposure. This was based on the fact that no workers entered the hotspot area underneath the Precoat tank during the brief period that the area was not properly controlled. In addition, the dose rates involved were not high enough to provide a substantial potential for overexposure. The licensee entered the issue into their CAP as NCR 532588. |
