| Title | Evaluate Inappropriate Characterization of Reactor Coolant System (RCS) Filters for Transportation and Disposal |
| Description | The inspectors identified an Unresolved Item (URI) regarding the significance of the inappropriate characterization of Reactor Coolant System (RCS) filters for transportation and disposal. During review of records related to a shipment of RCS filters (shipment W-09-36), the inspectors noted that the filter radionuclide concentrations were based on samples of Chemical and Volume Control System (CVCS) resin rather than representative samples of the filter media. This is contrary to the guidance in NRCs BTP on Waste Classification, Information Notice 86-20, and various industry reports. These documents describe spent resin and primary filters as separate waste streams that require independent, representative, sampling of each. This is due to the different properties of ion exchange resins and mechanical filters which tend to concentrate radioactive contaminants in differing concentrations. Discussions with shipping/radwaste staff indicated that this has been the practice for approximately five years. In order to disposition the significance of this finding, the NRC requires a comparison of10 CFR Part 61 analyses for the CVCS resin and RCS filter waste streams. The BTP states that, The staff considers a reasonable target for determining significant differences between measured or inferred radionuclide concentrations in separate samples is that the concentrations are accurate to within a factor of 10. If significant differences are identified, an analysis of the impact (significance) on any previous filter shipments to determine if any waste was misclassified also may be necessary.
