The NRC identified a non-cited violation o … The NRC identified a non-cited violation of Technical Specification (TS) 6.14, Offsite Dose Calculation Manual (ODCM), for failure to evaluate and provide sufficient information to support a change to the ODCM. Specifically, LGS revised the ODCM to allow the residual heat removal service water (RHRSW) monitors to be non-functional due to loss of flow for a period of up to 4 hours before they were required to be declared inoperable and did not provide sufficient information to support the change including a determination that the change would maintain the level of radioactive effluent release control. LGS entered the issue into their corrective action program (CAP) as Issue Report (IR) 1639697 and revised the applicable alarm response card (ARC-MRC-010 E4) to declare the monitor inoperable under similar conditions. A dose calculation was also completed that indicated no significant public dose consequences associated with the monitors inoperable status. The failure to evaluate and provide sufficient information to support a change to the ODCM, in accordance with the requirements of TS 6.14 is a performance deficiency. This performance deficiency is more than minor because it affected the Public Radiation Safety Cornerstone attribute of Plant Facilities/Equipment and Instrumentation. Using Inspection Manual Chapter 0609, Appendix D, Public Radiation Safety Significance Determination Process, dated February 12, 2008, the inspectors determined this to be a finding of very low safety significance (Green) because: the finding was in the effluent release program; was not a substantial failure to implement the effluent program; and the dose to the public did not exceed the 10 Code of Federal Regulations (CFR) Part 50 Appendix I criterion or 10 CFR 20.1301(e) limits. This finding was associated with a cross cutting aspect of Human Performance, Design Margins. Specifically, LGS did not conduct a sufficiently rigorous review of a change in the operability status of a safety-related radiation monitor (RHRSW radiation monitors) to ensure that the change would not adversely impact the level of radioactive effluent release control.l of radioactive effluent release control.
