| Title | Licensee-Identified Violation |
| Description | Technical Specification 5.5.4 requires the radioactive effluent controls program be contained in the offsite dose assessment manual and include limitations on the functional capability of radioactive liquid and gaseous monitoring instrumentation. Cooper Nuclear Station Offsite Dose Assessment Manual, Appendix D, Section D 3.3.2(a) requires the gaseous radiation monitoring instrumentation channels shown in Table D3.3.2-1 be operable with the minimum operable channels in service. The effluent process flow element associated with the elevated release point monitoring system is shown in Table D3.3.2-1 and the minimum number of operable channels is one. Under Condition B, the licensee is required to restore inoperable channels to operable status within 31 days. Contrary to this requirement, the licensee did not restore at least one channel of the elevated release point process flow monitor operable within 31 days. The 31-day period expired September 7, 2012, and at the time of the inspection, the process flow monitor was still not operable. As an interim corrective action to ensure the elevated release point gaseous effluent radiation monitor functioned in the absence of a flow rate signal, licensee representatives provided an electrical signal to simulate the signal provided by the process flow monitor. Licensee personnel said the signal provided was a conservative value, in that, it simulated a higherthan- actual flow rate, which would cause the radiation monitor alert setpoint to be reached at a lower concentration than required. The violation had very low safety significance because, although it involved an effluent program violation, it did not result in a substantial failure to implement the effluent program and it did not result in public doses exceeding either 10 CFR Part 50, Appendix I, values or 10 CFR 20.1301(e) values. The details were documented in Condition Report CR-CNS-2012-06010. |
