UK set to fork out ‘hundred of millions’ to fix Rolls Royce small nuclear reactor flaw.

 Energy crisis: UK set to fork out ‘hundred of millions’ to fix Rolls Royce reactor flaw. THE Government could be forced to spend hundreds of millions of pounds in an effort to tackle a key flaw of Rolls Royce
reactors, has been told.

As part of the Government’s energy security strategy, the UK has favoured small modular reactors as a way to boost its homegrown energy generation. In April, the Government announced that it is investing £210million to help develop small modular reactors (SMRs), which are said to be much cheaper and easier to deploy than traditional nuclear power stations.

However, a new study has found that SMRs will actually generate far more radioactive waste than conventional nuclear power plants, and governments to spend large amounts to find a safe way to dispose of it. Study lead author Lindsay Krall, a former MacArthur Postdoctoral Fellow at Stanford University’s Center for International Security and Cooperation (CISAC) said: “Our results show that most small modular reactor designs will actually increase the volume of nuclear waste in need of management and disposal, by factors of 2 to 30 for the reactors in our case study.

Dr Paul Dorfman, an associate Fellow at SPRU University of Sussex, who was not involved in the study said that the smaller the reactor is, the more neutron leakage would take place. He said: “To cut to the chase, SMRs should without question be producing higher volumes [of waste] than normal reactors. “It may well produce more high-level waste than conventional reactors, but will most definitely produce more low and
intermediate waste than conventional reactors. “

And that’s important, those intermediate and low are huge waste streams. “In terms of the Rolls
Royce, it’s a slightly bigger design, there is no way you can call it an SMR. “It would have fewer problems than the ones in the paper, but nevertheless, it would still produce more waste than a conventional
reactor, whichever way you put it.”
