| Title | January 2016 Groundwater Contamination |
| Description | The inspectors identified an URI related to whether a performance deficiency exists associated with Entergys controls to prevent the introduction of radioactivity into the site groundwater were adequate. Specifically, Entergy obtained increased tritium concentrations from groundwater MW samples in January 2016 indicating that a leak or spill had occurred allowing the introduction of radioactivity into the subsurface of the site. Entergy entered this issue into their CAP as CR-IP2-2016- 00264, CR-IP2-2016-00266, and CR-IP2-2016-00564 with actions to characterize and evaluate this new leak. The initial Entergy investigation focused on identifying the source of the contamination which was preliminarily determined to originate from the reject water of the RO skid that was in service from January 1631, 2016. This cause determination was based on the timing of the groundwater contamination event and based on the unique matching of the radionuclide signature from the groundwater samples and the RO skid reject water. Entergy has yet to identify the specific leakage pathway or the root cause for this event. An URI is initiated for further determination of whether a performance deficiency exists following Entergys finalization of their root cause analysis. |
