This specification invites contractors to submit a targeted proposal for a three-staged programme of further work in experimental methodology development and approaches for radionuclide behaviour parameter measurement applicable to NWS’s current knowledge gaps. At this stage, a proposal submitted in response to this Contract Technical Specification (CTS) should focus on Stage 1 of the work scope outlined below. A detailed, fully costed modular proposal for Stage 2 & 3 works is an anticipated output of Stage 1. The combined scope (Stages 1- 3) includes reviewing the global methodologies for acquiring site-specific radionuclide behaviour parameters, including development of a fully costed, modular work plan (Stage 1), and thereafter undertaking measurements to fill data gaps or to underpin safety arguments (Stage 2) and development of an optimised testing and analysis strategy (Stage 3), particularly in relation to relevant, UK-specific potential host rocks.
