Scenario assessment for advanced nuclear energy systems, including Molten Salt Reactors, in Europe

Nuclear-21 is partner in the EC MIMOSA project (2022-2026) investigating and maturing the option for Molten Salt Reactors (MSRs) to allow for the multi-recycling of spent nuclear fuel in Europe and thus reduce the spent fuel inventories while ensuring an affordable and responsible management of the nuclear materials. As Work Package 1 leader, we undertake the task to will devise and demonstrate risk-cost optimised integrated multi-recycling strategy of plutonium and uranium combining multi-recycling options in LWRs with recycling Pu and other transuranics today considered as waste in Cl MSRs using existing European infrastructures such as the Orano reprocessing plant in La Hague (France). We analyse country-per-country the possible nuclear energy system futures as well as integrated on EU-level with the gradual introduction of addition Light-Water Reactors (LWRs), Small Modular Reactors (SMRs) as well as fast reactors (FRs) and MSRs. All of these performing specific functions in an integrated nuclear energy system.

Secondly, we coordinate the roadmap development towards such futures i.e. including market prospects, technology and regulatory challenges towards such option.

We integrate hereby our NESSAT Toolbox and our extensive expertise and experience with different reactor technologies and fuel cycle options while keeping a clear technology-to-business focus aimed at presenting tangible scenarios deployable before 2050.
