| Title | Failure to Follow Procedure and Technical Specification Associated with Control for High and Locked High Radiation Areas |
| Description | The inspectors identified a self-revealed finding of very low safety significance and an associated NCV of Technical Specification 5.7.1 when licensee personnel failed to adequately monitor and provide positive control over activities within a high radiation area that was greater than 100 millirem per hour (mrem/hr) but less than or equal to 1000 mrem/hr from a radiation source which was created during the cycling of valve 1RH8701B inside the missile barrier in containment. A slug of material dislodged from the valve and was transported to a location that resulted in localized elevated dose rates where an individual was performing work. As an immediate corrective action, the licensee instituted appropriate radiation protection controls and initiated an Apparent Cause Evaluation (ACE) to review the event in more detail. The licensee entered this issue into their CAP as IR 1559430, ED [Electronic Dosimeter] Dose Rate Alarm Received. The performance deficiency was more than minor because, if left uncorrected, it would have the potential to lead to a more significant safety concern. Specifically, not evaluating the radiological impact of the slug of radioactive material being transported to an area where a worker was performing work caused the worker to receive unnecessary and unplanned exposure to radiation that if left uncorrected could lead to a more significant safety concern in that a worker could receive a much higher dose under different circumstances. The inspectors determined that the finding was of very low safety significance (Green) using IMC 0609, Appendix C. This finding had a crosscutting aspect in the Work Practices component of the Human Performance crosscutting area because licensee personnel failed to validate and communicate th
changing dose rates of the work area after Operations personnel performed work that affected the dose rates in the work area (H.4(a)). (Section 2RS1.6b). |
