Radioactive Waste Management (RWM) has recently published the third annual report of the DECOVALEX-2019 project. DECOVALEX is a long-standing international collaboration between waste management organisations, regulators, research institutions and their supporting organisations, investigating complex coupled thermal-hydraulic-mechanical-chemical processes in the sub-surface, with a particular focus on radioactive waste management.
Quintessa have been supporting RWM in two tasks; Task A: "modElliNg Gas INjection ExpERiments (ENGINEER)" and Task E: "Upscaling of modelling results from small scale to one-to-one scale". The third annual report summarises the main work performed in 2018 and 2019, building on two previous annual reports, including key insights under both tasks.
A final report will be available soon giving a full synthesis of the key learning from this phase of DECOVALEX and the implications for the UK radioactive waste programme.
