Mott MacDonald reaches SMR research milestone

NCE stock nuclear

A phase of research into a major project looking at alternative nuclear technologies has been completed by Mott MacDonald.

The company has completed the third phase of its System Requirements for Alternative Nuclear Technologies (ANT) project, commissioned by the Energy Technologies Institute (ETI).

The research has contributed to a report from the ETI saying that small modular reactors could be operating in the UK by 2030, and calling on the government to help encourage early investor confidence.

As part of the research, Mott MacDonald carried out engineering and cost modelling services to determine the feasibility of extracting heat from light water reactor-type SMR steam cycles to supply district heat networks. The results showed that it was technically feasible, relatively easy to implement, and cost implications were modest.

“Meeting the UK’s climate change obligations will require new sources of low carbon heat and hot water in our buildings. Large-scale district heat networks, like those currently used in Copenhagen and Helsinki, are a potential solution to this challenge and our work shows that SMRs could be a viable source of heat for these networks, as well as electricity for the national grid,” said Mott MacDonald project manager Sam Friggens.
