ONR-RD-FW-001 - Risk-informed regulatory decision-making (RIRDM)

This document sets out ONR's risk-based framework for making regulatory decisions. It discusses the tolerability of risk concept, which is at the heart of our framework, and its relationship to the law. It also discusses how tolerability of risk can be applied to the specific challenges presented by the nuclear industry and clarifies how we take account of wider factors in reaching our overall regulatory decisions. It consolidates into one document the approaches already embedded within our other publications.

This document is aimed primarily at stakeholders who want to know more about our risk-based framework for making regulatory decisions. The framework contributes to securing the health, safety, and welfare of persons at work and for protecting others against risks to health and safety arising from work activities in the nuclear industry. It sets out the framework and criteria by which we, in complying with our regulatory purposes, make our decisions. It describes how we consider scientific evidence and uncertainties, and how we strike the balance between the benefits and disadvantages of adopting a measure, to avoid or control the risks.
