With funding recently confirmed for a new nuclear power station in Suffolk, Dr Ian Fairlie, CND Vice-President and science adviser and a leading consultant on radioactivity in the environment, questions whether we actually need this development and the technology in general.
In recent months, the government has continued to promote nuclear reactors. For example, the Energy Secretary is now asking GB Energy to assess sites to be used to host new nuclear reactors. And the Prime Minister continues to push for so-called Small Modular Reactors and has backed the US President’s wishful thinking of ‘a golden age of nuclear’.
But these announcements and proposals are mostly pie-in-the-sky statements and should be treated with a pinch (or more) of salt, as the reality is otherwise.
Let’s look at what is happening in the rest of the world. Last year, a record 582 GW of renewable energy generation capacity was added to the world’s supplies: almost no new nuclear was added.
Indeed, each year, new renewables add about 200 times more global electricity than new nuclear does.
Of course, there are powerful economic arguments for this. The main one is that the marginal (i.e. fuel) costs of renewable energy are close to zero, whereas nuclear fuel is extremely expensive. Nuclear costs – for both construction and generation – are very high and rising, and long delays are the norm. For example, the proposed Sizewell C nuclear station is now predicted to cost £47 billion, with the government and independent experts acknowledging even this estimate may rise significantly. The upshot is that new nuclear power means massive costs, a poisoned legacy to future generations, and whopping radioactive pollution.
Given these manifest disadvantages, independent commentators have questioned the government’s seeming obsession with nuclear power. It is not that nuclear provides a good solution to global warming: it doesn’t. The United Nations’ Intergovernmental Panel on Climate Change (IPCC) reports that renewables are now 10 times more efficient than new nuclear at CO2 mitigation. It’s not that AI centres will need nuclear: the International Energy Agency expects data centres will cause a mere 10% of global electricity demand growth to 2030. And it forecasts that the renewables will supply 10 to 20 times the electricity required for data-centre growth, with Bloomberg NEF predicting a 100-fold renewables expansion.
As for so-called Small Modular Reactors, the inconvenient truth is that these designs are all just paper designs and are a long way off. They would also be more expensive to run than large reactors per kWh – the key parameter. And as the former Chair of the US government’s Nuclear Regulatory Commission (NRC) says, SMRs will produce more chemical and radioactive waste per KW produced than large reactors.
Given a UK Treasury strapped for cash, the unsolved problem of radioactive nuclear waste, the spectre of nuclear proliferation, and it’s being a target in future wars, many wonder why the government is so fixated with nuclear power.
Well, the answer was supplied in 2023 by the Rishi Sunak administration which admitted that the main reason for its continued eye-watering financial support for civil reactors was that they provided needed technical support and expertise for the government’s nuclear weapons programme.
