History of risk regulation, including Basic Safety Standards

Theme leads: Ted Lazo, edward.lazo@oecd.org and Markku Lehtonen, m.lehtonen@sussex.ac.uk

This session will address the evolution of risk estimation by various actors, including current scientific understanding, to give an historic perspective to our current approaches to radiological risk regulation and its implementation through ALARA and the Basic Safety Standards. From a more sociological standpoint, this session will also address how stakeholders have been involved in risk regulation, and how their views, needs and opinions have influenced radiological risk regulation and implementation, in particular through ALARA, the BSS, and specific national regulations.

Regulation and management of risks related to nuclear installations have, throughout the history of nuclear power, developed in reaction to major accidents (Windscale, TMI, Chernobyl, Fukushima), and also through increasing international collaboration, especially within international organisations such as IAEA, OECD-NEA and WENRA. Improvements in regulation and management have included technical, organisational and human factors aspects, with particular emphasis on clearly separating responsibilities of organisations responsible for R&D, development, operation and regulation of nuclear installations. This has included increased transparency, greater independence of regulatory authorities, but also greater involvement of civil society. While international coordination is advancing, it is not clear whether or not this influences national regulatory regimes, or in fact whether national authorities have followed their own country-specific trajectories? 

Contributions sought to this session can address the historical development of radiological risk regulation and management, from a comparative inter-country perspective, or examine the evolution within a single country or region.

Possible topics include but are not limited to the implementation of Basic Safety Standards, impact of major accidents, the shifting role of economic considerations, the role of international collaboration, and the role of civil society in the evolution of risk management and regulation.
