Yesterday, the UK Nuclear Decommissioning Authority (NDA) released their annual report and, as surely as night follows day, the news is that the bill for decommissioning and cleaning up our existing nuclear plants is rising. And rising. And rising.

In fact, we could have funded two London Olympics just from the rises in the estimated costs over the past two years.

Although no one really has a precise figure (and the NDA admits it can't tell us what the final bill will be), the estimate now stands at around £73bn - about the same amount as the Apollo Moon Landings cost*.
