| Title | Failure to Implement Appropriate Radiological Controls After Radiation Protection Identified that a Worker Was Potentially Contaminated Due to Inappropriate Protective Clothing |
| Description | A self-revealed finding of very low safety significance and an associated non-cited violation of Technical Specification 5.4.1.a was identified. Specifically, the licensee failed to implement appropriate radiological controls after radiation protection identified that a worker was potentially contaminated due to inappropriate protective clothing. The issue was entered in the licensees corrective action program as AR 01017724. The licensees corrective actions included the replacement of all contamination monitors used at the site. The new contamination monitors have a radon subtract feature designed to mitigate the large number of nuisance alarms caused by radon interference at this site. The finding is more than minor because, if left uncorrected, the performance deficiency would have the potential to lead to a more significant safety concern. Specifically, bypassing every level of defense could result in additional dose to workers outside the radiological control area. The finding was assessed using the Significance Determination Process and was determined to be of very-low safety significance because these radioactive material control issues were not related to transportation and dose to members of the public was less than 0.005 rem. The inspectors observed the operation of the new contamination monitors and response of radiation protection technicians assigned to monitor authorized exit points during a refueling outage. The new monitors did not exhibit nuisance alarms and the technicians treated every alarm as a potential contamination event until proven otherwise with another instrument. Furthermore, these technicians informed the inspectors that they received a briefing before the outage by the radiation protection manager about alarm response expectations. The inspectors determined that the events involved in this performance deficiency are not indicative of current performance. Consequently, the inspectors did not assess the performance deficiency for cross-cutting aspects. |
