NUCLEAR waste should be buried in huge concrete tanks, according to the Committee for Radioactive Waste Management.
The committee's final report, published this week, favours development of a single repository, valued at around £10 billion, to contain low level, intermediate and high level waste.
Professor Richard Green, director of the Institute of Energy Policy and Research at the University of Birmingham, said: 'The issue of nuclear waste has to be sorted out before the decision on new build can go ahead. With the first generation of nuclear power plants the technology was not very advanced and as a result there is a great deal more uranium in the waste produced.
This waste needs to be dealt with safely and efficiently.'
The first waste store in the UK's current decommissioning programme is being built at Sellafield in Cumbria. Carillion is constructing a £118 million facility to store intermediate level waste at the site.
