There is an increasing expectation by the public to be informed and understand the rationale behind decisions especially in areas where peopleís safety or health may be affected. This is particularly true for new industrial activities including those occurring in the nuclear industry, which in the past limited communications to highly technical experts. This is one of the reasons why Nuclear Regulatory Organisations are increasingly involved in transparency. Most regulators have developed public information and communication policies in order to establish public confidence in their information. This report, resulting from exchange of experience between the WGPC members, highlights the main challenges to be addressed for efficiently making regulatory decisions public and the various means implemented in member countries to reach this objective.
