| Title | Reactor Scram Due to Seal Oil Leak for Main Generator |
| Description | A self-revealing noncited violation of Technical Specification 5.7.1 was identified for failure to barricade and conspicuously post a high radiation area. On April 14, 2009, equipment drain radioactive tank 5 was completely drained which created an unposted high radiation area. Two workers near the tank area received dose rate alarms indicating that unexpected radiological conditions existed. Radiation protection personnel responded to the area, performed surveys, and found an unexpected high radiation area outside of the posted high radiation area boundary. The highest dose rate outside the existing boundary was approximately 200 millirem/hour. The licensee entered this item into their corrective action program as Action Request 195295. The failure to barricade and conspicuously post a high radiation area is a performance deficiency. The finding was greater than minor because it was associated with the Occupational Radiation Safety Cornerstone attribute (exposure control) of program and process and affected the cornerstone objective, in that, failure to post a high radiation area impacted the ability to adequately protect workers health and safety from exposure to radiation. Using Inspection Manual Chapter 0609, Appendix C, Occupational Radiation Safety Significance Determination Process, the finding was determined to be of very low safety significance because it was not an as low as is reasonably achievable finding, there was no overexposure or substantial potential for an overexposure, and the ability to assess dose was not compromised. Additionally, this finding had human performance crosscutting aspects associated with work control in that the work planning did not appropriately plan work activities by incorporating risk insights and radiological safety H.3(a) |
