Efficiency in decision-making by governmental authorities is increasingly dependent upon public trust. Public communication is one of the keys to the future of nuclear power. A workshop on regulatory public communication, held in Paris in December 2000, highlighted the importance of public confidence in nuclear regulators. In recognition of this, the Committee on Nuclear Regulatory Activities (CNRA) set up in 2001 the Working Group on Public Communication of Nuclear Regulatory Organisations (WGPC). The purpose of the WGPC is to facilitate the exchange of information, news, documents, experiences and practices among nuclear regulatory organisation communicators. It also aims to exchange views regarding the policies of nuclear regulatory organisations in the area of public communication and identify ways of promoting efficient collaboration.
