| Title | Turbine Building Differential Pressure Indicating Positive |
| Description | An NRC-identified finding of very low safety significance with an associated NCV of 10 CFR 20.1302 was identified for failure to take action to prevent a potential unmonitored release on August 3, 2011, when the turbine building differential pressure indicated positive on the building differential pressure indication in the main control room. This issue was entered into the licensees corrective action program as IR 1247501. Immediate corrective action included determination that the turbine building was still at a negative differential pressure and no unmonitored release path existed. The performance deficiency was more than minor because it adversely affected the Public Radiation Safety Cornerstone objective to ensure adequate protection of public health and safety from exposure to radioactive materials released into the public domain as a result of routine civilian nuclear reactor operation. Failure to perform surveys when indicated conditions warrant increases the possibility that an unmonitored release could occur. Using IMC 0609, Appendix D, Public Radiation Safety Significance Determination Process, radioactive material control program flowchart, there was no public exposure, and this finding was screened as Green, or very low safety significance. The inspectors identified that this finding had a cross-cutting aspect in the area of Human Performance - Work Practices because operators failed to follow the steps of the annunciator response procedure |
