Backers of the controversial MOX plant at Sellafield, which promised to turn toxic waste into a useable fuel that could be sold worldwide, had claimed the plant would make a profit of more than £200m in its lifetime, producing 120 tonnes of recycled fuel a year.
But an investigation published in today's Independent newspaper reveals what the government has been trying to keep secret - that technical problems and a dearth in orders has meant it has produced just 6.3 tonnes of fuel since opening in 2001.
Since building work began in the 1990s the plant has absorbed over £1 billion in public subsidies - money which could have been far better invested in developing renewable energy projects.
