Safe systems?

The Evening Post headline 'Oldbury deemed safe' is misleading as it makes no sense to declare something 'safe' ie free from risk. This is not what the assessments of UK nuclear power stations have tried to do. What does make sense is to talk about degrees of risk ie the probability occurrence of various hazards. 'No major weaknesses' in UK nuclear stations is not the same as safe - better to say that certain risks have been found to be low probability. The development of life on Earth is thought to be an extremely low probability event - but here we are!
