| Title | Water with Tritium Identified in Excavation Area within the Protected Area |
| Description | No findings of significance were identified. An unresolved item (URI) was identified to review AmerGens corrective action program evaluation (IR 815415) regarding the identification of tritium in a September 8, 2008 surface water sample from a puddle of water in an excavation area within the protected area. Based on preliminary reviews and observations, the inspectors did not identify an immediate public health and safety concern. In addition, no indication of contamination of drinking water aquifers was identified by the inspectors. AmerGen performed an initial evaluation to determine the potential source of the tritium in the samples collected. The evaluation included a review of potential active or historical leakage in the area; potential occurrence of a water spill associated with cutting of the torus water storage tank piping located in the excavation area; problems with water sampling (including sample collection, preparation, and counting); and potential washout of tritium from station effluents. To support their evaluation, AmerGen collected groundwater samples from various wells surrounding the area and collected multiple soil samples along the length of the TWST piping, including the location of the puddle. AmerGens evaluation, which continued at the conclusion of this inspection period, indicated the likely cause of the indication of tritium in the water sample was due to an inadvertent cross-contamination of the sample from the use of glassware in the chemistry laboratory. The evaluation also initially concluded that the indication of tritium was not due to a past spill or an active pipe leak, that water had not spilled during cutting of piping in the excavation area, or that rain water washout caused tritium to appear in the sample of the water puddle. AmerGen initiated corrective actions to improve sample preparation and counting, including detection of potential sample cross-contamination. The inspectors plan to review this evaluation after it is completed. (URI 05000219/2008004-02, Water with Tritium Identified in Excavation Area within the Protected Area) |
