| Title | Failure to Survey |
| Description | The team reviewed a self-revealing noncited violation of 10 CFR Part 20.1501 (a), for the failure to survey the residual heat removal pump A room after it was secured from service. Specifically, on August 29, 2011, during a tour with the NRC inspection team, the residual heat removal system engineer received a dose rate alarm. The team left the area and contacted radiation protection. Subsequent surveys identified dose rates were as high as 120 millirem per hour at 30 centimeters from the suction piping of the pump, which required the area to be posted and barricaded as a high radiation area. The licensee appropriately controlled the area, and entered the condition into their corrective action program as Action Request/Condition Report 247542. The finding was more than minor because it was associated with the Occupational Radiation Safety Cornerstone exposure control attribute of program and process and it affected the cornerstone objective because it resulted in an unposted high radiation area that affected the licensee\'s 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 ALARA finding, there was no overexposure or substantial potential for an overexposure, and the ability to assess dose was not compromised. In addition, this finding had a crosscutting aspect in the area of human performance associated with the work control component, because the planned work activities did not incorporate the need for compensatory actions (e.g., surveys) to detect delayed changes in radiological conditions H.3(a). |
