| Title | Licensee-Identified Violation |
| Description | Technical Specification 5.5.1 requires implementation of the Offsite Dose Calculation Manual. Offsite Dose Calculation Manual, Revision 8, Part 12.2.1, Radioactive Liquid Effluent Monitoring Instrumentation, Section C requires that when the service water effluent gross activity monitor is operated with less than the minimum number of operable channels, the licensee shall collect and analyze grab samples for beta or gamma activity once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. Contrary to the above, grab samples were not collected while the Unit 1 service water effluent gross activity monitor was inoperable from June 2-20, 2009. Specifically, following fuse replacement, the licensee failed to recognize that the instrument remained uninitialized; therefore, that compensatory samples were required. The finding was documented in the licensees corrective action program as IR 933472. Corrective actions included returning the monitor to service and reviewing captured monitor data from June 2-20, 2009, to ensure that no release events occurred during the monitor outage, revising the monitor repair and maintenance procedures to clear direct communication with the Chemistry Department subject matter experts during work on the system, and reinforcing the expectation that control room operators turn over all abnormal indications to supervisors each shift. The finding was determined to be of very low safety significance because, although the finding related to the effluent release program, it was not a failure to implement the effluent program or an event that resulted in a dose to the public in excess of Appendix I criterion or 10 CFR 20.1301(e) |
