De Brauw has advised the start-up Thorizon on securing EUR 20 million in funding to accelerate the development of its innovative molten salt reactor technology that uses nuclear waste as fuel. The EUR 20M will fund prototyping, licensing and demonstration of Thorizon One’s cartridge fuel system, a game-changer towards molten salt reactor industrialization.

The funding round was led by the Dutch National Promotional Institution, Invest-NL, backed by an InvestEU guarantee from the European Commission for the research part, with strong backing from Positron Ventures, PDENH, and Impuls Zeeland. All of Thorizon’s existing shareholders have reinforced their commitment in this investment round.

With this latest investment, Thorizon has now raised a total of EUR 42.5 million.
