Unfortunately, the role of the Authority has already been radically changed since it was originally proposed. The NDA is now continuing to oversee the operation of nuclear facilities which create nuclear waste - thus adding to a major problem. For example, the NDA runs BNFL's ageing, loss-making Magnox reactors, plus two spent nuclear fuel reprocessing plants and a MOX plant at Sellafield. This will mean an ever increasing bill for the taxpayer.
