Government should define the tolerability of risk for nuclear

Define tolerability of risk

Full Recommendation Text

The Government should take responsibility for defining the Tolerability of Risk for the nuclear sector. In doing this, the Government should consider the modern state of the nuclear sector, and the societal demand for its outputs across energy, decommissioning and defence. This should be clearly communicated to regulators and periodically reviewed.

The Government should make a direction to the ONR under section 92 of the Energy Act 2013 and to the EA section 40 of the Environment Act 1995 so that, in exercising their functions, risks at or below broadly acceptable levels are deemed to be ALARP and ALARA unless there are strong and compelling reasons to the contrary.

This direction and definition should form the basis of the revision of the guidance in recommendation 7.
