[en] This document is a compilation of review comments on the Engineering Test Plan (ETP) for field radionuclide migration experiments in the Climax granite. This investigation was managed by the Nevada Nuclear Waste Storage Investigations (NNWSI) and the principal NNWSI participant organization conducting the investigation was Lawrence Livermore National Laboratory (LLNL). An NWTS decision to cease funding for the ETP, along with an NNWSI decision that sufficient knowledge had been gained to support their tuff evaluation, has resulted in the termination of the Plan as emphasis was shifted away from this study in the Climax granite. The purpose of this granite radionuclide migration peer review was to complete the assessment of the ETP so that the Plan could be finalized and the technical community could take advantage of the extensive generic National Waste Terminal Storage (NWTS) research conducted by the NNWSI for the Office of Nuclear Waste Isolation (ONWI). The objectives of this investigation were: to develop equipment and procedures for a reliable field migration test that can be used at candidate repository sites in fractured rock; determine field retardation factors for selected radionuclides that can be compared to laboratory measured values; and provide input to mass transport models that will improve the ability to make dependable pretest predictions and aid in data interpretations
