Thorizon–TNO molten-salt reactor materials programme

Thorizon and TNO announced a TNO-led materials and corrosion programme to generate experimental data and predictive models for PIONEER licensing and later Thorizon One deployment. Initial work is under way in Amsterdam and Petten, with wider Dutch and international partners still prospective. This research agreement establishes no completed material qualification, reactor order, new site commitment or permission.

Not a deployment project. SMR plans, agreements, studies and government programmes that are not (yet) a single deployment project. They are listed separately and are never counted as projects or reactors.
