Rising to four floors at the sprawling Sellafield complex on the Cumbrian coast, it is probably one of the biggest technical and economic disasters in the history of the British nuclear industry. For an industry with more than its fair share of mishaps, that is saying something.

The plant was originally meant to process 120 tonnes of MOX fuel a year, but it has yet to manage even three tonnes a year. As the Guardian reported in February, a grand total of only 5.2 tonnes have been produced in the six-year commissioning phase from 2001 to 2007.
