N2  - It is clear that probabilistic risk assessment or probabilistic safety assessment is embedded in the safety culture of the nuclear power industry, worldwide. Risk assessment applications are in transition in the sense that the regulatory apparatus is not yet in place, at least in the United States of America (USA), to fully support a risk-based licensing process. There is progress on the regulatory front, but it is tedious and not without its frustrations. Currently, the strategy in the USA is a "risk-informed" approach that tends to be "business as usual", but while you're at it, "do a risk assessment". The result is added burden (and costs) at a time of increased competition in the power field as a result of deregulation. There is hope in that some steps are finally being taken to modify the regulations to allow risk assessment to be more of a part of the licensing process. For example, the regulations having to do with maintenance, plant changes, and technical specifications have been modified to allow insights from risk assessment to be part of the basis for licensing amendments. On the matter of standards there is strong support that is scientifically based and addresses such issues as health effects and environmental impacts. There appears to be less support for standards on such matters as definition of terms, methodology, and data requirements.<p />
