The agreement positions Rolls-Royce as the primary SMR provider with multiple binding commitments in Europe, building upon similar contracts in the UK and the Czech Republic. In the Czech Republic, CEZ is targeting up to 3 GW of capacity while securing a 20% equity stake in the company’s SMR subsidiary. These projects utilize a 470 MWe pressurized-water design, a modular approach that the company is now expanding through international research partnerships.

Simultaneously, the firm is collaborating with the UK National Nuclear Laboratory and Japan’s JAEA to accelerate High-Temperature Gas-Cooled Reactor technology. This initiative focuses on the next generation of coated particle fuel, leveraging historical UK research from the 1960s to create accident-tolerant energy solutions. Despite these technological strides and the company's involvement in the US Department of Defense’s Project Pele, the transition from design to physical construction remains a hurdle. With ongoing site preparations in the UK and broader industry challenges regarding the supply of nuclear-grade steel, the timeline to reaching operational criticality for these new facilities remains uncertain.
