Violent weather events have been top of the news agenda for weeks, with scientists and fact-based news organisations attributing their increased severity to climate breakdown. The scientists consulted have all emphasised the need to cut greenhouse gas emissions.
At the same time there are predictions about artificial intelligence and datacentres urgently needing vast amounts of new electricity sources to keep them running. Small modular nuclear reactors (SMRs) have been touted as the green solution. The reports suggest that SMRs are just around the corner and will be up and running in the 2030s. Google first ordered seven, followed by Amazon, Microsoft and Meta each ordering more.
With billions of dollars on offer, many startup and established nuclear companies are getting in on the act. More than 90 separate designs for SMRs are being marketed across the world. Many governments, including the UK, are pouring money into design competitions and other ways to incentivise development.
In all this there is a credibility gap. None of the reactor designs have left the drawing board, prototypes have not been built or safety checks begun, and costs are at best optimistic guesses. SMRs may succeed, but let big tech gamble their spare billions on them while the rest of us are building cheap renewables we know work.
