All that the Nuclear Decommissioning Authority (NDA), which runs THORP on behalf of the government, will say is that the plant has employed 500 people and costs £70 million a year to run. Even after it has closed it will cost £35 million a year to maintain for 10 years while it is cleaned out. Final demolition is set for 2095 with a price tag of £4 billion, a lot more than THORP cost to build.
The fundamental issue, however, was THORP’s failure to achieve its purpose. In order to justify its existence the plutonium and uranium should have been re-used for peaceful purposes. Plans for the new generation of fast breeder reactors that could have used the plutonium were abandoned, so in order to show they were using some of the product from the plant BNFL added another factory. This was to make new reactor fuel, made of mixed oxides of plutonium and uranium (MOX), using material recycled from THORP.
This project was also mired in controversy, but the government insisted on going ahead. It ended in abject failure because the plant failed to work. Instead of producing 120 tons of MOX fuel a year it made just 13.8 tons in nine years and was abandoned in 2011. A government report into the plant concluded in 2013 that this new factory added to THORP had lost taxpayers £2.2 bn.
Despite the reasons for THORP’s existence being comprehensively undermined, the plant continued. This was principally because it still had unfulfilled contracts from foreign customers to reprocess spent fuel, earning money producing plutonium and uranium that no one has a use for – except perhaps a terrorist.
