Title

Licensee-Identified Violation

Description

Technical Specification 5.4.1, states, in part, that written procedures shall be established, implemented, and maintained covering the applicable procedures recommended in Regulatory Guide 1.33, Revision 2, Appendix A, February 1978. Regulatory Guide 1.33, Quality Assurance Program Requirements, Appendix A, Section 7.d, requires procedures for BWR Air Extraction, Offgas Treatment, and Other Gaseous Effluent Systems including sampling, ventilation, and stack monitor. Station Procedure Technical Requirements Manual, Section 3.3.11.3, requires, in part, that with both of the main plant exhaust noble gas effluent radiation monitors (RMS-RE-125 and RMS-RE-126) out of service, the licensee perform grab samples release path once per 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months , and if the licensee were to exceed the 12-hour grab sampling action time requirement, immediately suspend release of radioactive gaseous effluents via this pathway. Contrary to the above, on March 7, 2015, the licensee had both of the main plant exhaust noble gas effluent radiation monitors out of service and failed to perform grab samples of the main plant exhaust noble gas effluent release path once per 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months . Additionally, once the licensee exceeded the 12-hour grab sampling action time requirement, the licensee failed to immediately suspend radioactive gaseous effluents via this pathway. The licensees failure to initiate timely compensatory effluent sample collection and analysis as required by the stations Technical Requirement Manual when the main plant exhaust duct noble gas radiation monitors were out of service was a performance deficiency. This performance deficiency is more than minor, and therefore a finding, because it adversely affects the Public Radiation Safety Cornerstone, in that, by not performing auxiliary sampling of the main plant exhaust duct, the licensee was not monitoring effluents being released from the main plant exhaust duct for about 15 hours1.736111e-4 days 0.00417 hours 2.480159e-5 weeks 5.7075e-6 months . Using NRC Inspection Manual Chapter 0609, Appendix D, Public Radiation Safety Significance Determination Process, dated February 12, 2008, the inspectors determined the violation was of very low safety significance (Green) because 1) it was a finding in the effluent release program and 2) there was no failure to implement the effluent program. As corrective action, the licensee performed a human performance evaluation and entered the issue into their corrective action program as Condition Report CR-RBS-2015-01784.
