| Title | Failure to take required compensatory actions for 1 and 2 RIA-40 condenser offgas radiation monitor inoperability |
| Description | An NRC-identified Non-Cited Violation (NCV) of Technical Specification 5.4.1.d, for failure to follow procedures NSD 513, Primary to Secondary Leak Monitoring Program, and OP/0/A/1106/031, Primary to Secondary Leak Rate Monitoring and Instrumentation, which required compensatory actions and compensatory sampling during certain times when RIA- 40 (Condenser Off-Gas Radiation Monitor) was out of service. This violation was entered into the licensees corrective action program under PIP O-10-06151. The failure to recognize that the condenser off-gas radiation monitors were inoperable was a performance deficiency. This performance deficiency is more than minor because it was associated with the equipment performance attribute of the Mitigating Systems Cornerstone, and adversely affected the cornerstone objective in that the capability to detect, quantify, and respond to primary to secondary leakage was degraded. The inspectors evaluated the significance of this finding using inspection Manual Chapter 0609.04, Phase 1-Initial Screening and Characterization of Findings, and determined this finding was of very low safety significance (Green) because the finding did not result in a loss of safety function. This finding had a cross-cutting aspect in the area of Problem Identification and Resolution under the Corrective Action Program component because the licensee failed to recognize that 1, 2 RIA-40 were inoperable, and to take appropriate corrective actions to address the issue in a comprehensive manner commensurate with its safety significance and complexity [P.1 (d)] (Section 2RS6). |
