Title | Failure to Establish Component Cooling Water Radiation Monitoring Procedures |
Description | The inspectors identified a noncited violation of Technical Specification 5.5.1.1.a, \"Scope,\" involving the failure to establish procedures for component cooling water system alignments such that leakage of radionuclides to the environment would be monitored during all operational alignments of component cooling water. Specifically, radiation monitors could be aligned to only one train of component cooling water at a time and the licensee\'s procedures had no provision for monitoring the second train when both trains were in-service. This finding was entered into the licensee\'s corrective action program as Nuclear It Notification 200871387, and actions were implemented to require periodic grab sampling of the train which was not being monitored. The inspectors determined that this finding was more than minor because this issue impacted the Public Radiation Protection Cornerstone and its 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. Specifically, the radiation monitors for component cooling water were not sufficient to ensure adequate release measurements. The inspectors evaluated the significance of this finding using Phase 1 of Inspection Manual Chapter 0609.04 and determined that the finding screened to Inspection Manual Chapter 0609, Appendix D, \"Public Radiation Safety Significance Determination Process.\" The inspectors evaluated the significance of this finding using Inspection Manual Chapter 0609, Appendix D, and determined that the finding was of very low safety significance (Green) because dose did not exceed Appendix I criteria. This finding was determined to have a crosscutting aspect in the area of problem identification and resolution associated with the corrective action program in that the plant operators did not have a low threshold for identifying deficiencies in procedures. |
