A Swedish professor Janne Wallenius recently got a government grant of 100 msek for building the same thing. But his smr is lead-cooled and supposedly much safer than a pwr reactor which can overheat. The advantages are supposedly the same as with Rolls-Royce's reactor; low construction-costs due to standardized design. In a recent interview he stated that his design could be ready for mass-production in the mid 2030's.
