"Steve Thomas, a professor of energy policy at the University of Greenwich, said: “Despite 65 years of using nuclear power in Britain, we are still, at best, decades away from having facilities to safely dispose of the waste. Until we know this can be done, it is premature to embark on a major new programme of nuclear power plants.”
As Boris Johnson prepares a new push for nuclear power, the £131bn problem of how to safely dispose of vast volumes of radioactive waste created by the last British atomic energy programme remains unsolved.
The hugely expensive and dangerous legacy of the UK’s 20th-century nuclear revolution amounts to 700,000 cubic metres of toxic waste – roughly the volume of 6,000 doubledecker buses. Much of it is stored at Sellafield in Cumbria, which the Office for Nuclear Regulation says is one of the most complex and hazardous nuclear sites in the world.
As yet, there is nowhere to safely and permanently deposit this waste. Nearly 50 years ago the solution of a deep geological disposal facility (GDF) was put forward, but decades later the UK is no nearer to building one.
Experts say new nuclear facilities will only add to the problem of what to do with radioactive waste from nuclear energy and that the “back end” issue of the hazardous toxic waste from the technology must not be hidden. An assessment by the Nuclear Decommissioning Authority (NDA) says spent fuel from new nuclear reactors will be of such high temperatures it would need to stay on site for 140 years before it could be removed to a GDF, if one is ever built in the UK.
