Research review shows that nuclear safety is valued too low via Phys.org

New research has shown that the benchmark used by the Office for Nuclear Regulation for judging how much should be spent on nuclear safety has no basis in evidence and places insufficient value on human life. The review suggests it may need to be ten times higher – between £16 million and £22 million per life saved.

The research review led by Professor Philip Thomas from the University of Bristol and Dr Ian Waddington and published in the journal Nuclear Future, examined the evidence for the “value of a prevented fatality” (VPF) currently used as a safety guideline by the Office of Nuclear Regulation, the Health and Safety Executive and numerous Government departments.

The VPF figure of £1.83 million (published in July 2016) emerged from a 20-year-old small-scale opinion survey of 167 people and its interpretation method has recently been shown to be too flawed to be credible.

The VPF study team came up with the current UK figure after setting aside the results of their first opinion survey, but a recent re-analysis has shown that the discarded valuations were actually entirely rational and understandable and the VPF study team rejected the wrong survey. An up-to-date interpretation of the first would suggest that the VPF should be set about ten times higher than at present, at between £16 million and £22 million per life saved.

The Judgement- or J-value, a new method pioneered by Professor Thomas that assesses how much should be spent to protect human life and the environment that has recently been validated against pan-national data, would value life about four times higher, closer to the value used by the US Department of Transportation ($9.1 million in 2012).

Philip Thomas, Professor of Risk Management in the Department of Civil Engineering, said: “The Office of Nuclear Regulation and other national bodies clearly have a problem with how they should assess the right level of expenditure to protect people from nuclear and other accidents.
