The purpose of this book is to support IAEA training courses and workshops in the field of regulatory control of nuclear power plants as well as to support the regulatory bodies of Member States in their own training activities. The target group is the professional staff members of nuclear safety regulatory bodies supervising nuclear power plants and having duties and responsibilities in the following regulatory fields: regulatory framework; regulatory organization; regulatory guidance; licensing and licensing documents; assessment of safety; and regulatory inspection and enforcement. Important topics such as regulatory competence and quality of regulatory work as well as emergency preparedness and public communication are also covered.

The book also presents the key issues of nuclear safety such as "defence-in-depth" and safety culture and explains how these should be taken into account in regulatory work e.g. during safety assessment and regulatory inspection. The book also reflects how nuclear safety has been developed during the years on the basis of operating experience feedback and results of safety research by giving topical examples. The examples cover development of operating procedures and accident management to cope with complicated incidents and severe accidents to stress the importance of regulatory role in nuclear safety research.

The main target group is new staff members of regulatory bodies, but the book also offers good examples for more experienced inspectors to be used as comparison and discussion basis in internal workshops organized by the regulatory bodies for refreshing and continuing training.

The book was originally compiled on the basis of presentations provided during the two regulatory control training courses in 1997 and 1998. The written presentations were collected from the lecturers and compiled before and during the consultants meeting from 16-20 November 1998 in Vienna where final compilation was done. The text book was reviewed at the beginning of the years 2000 and 2002 by IAEA staff members and consistency with the latest revisions of safety standards have been ensured. The text book was completed in the consultants meeting at the end of 2001 by adding updates on the Nuclear Safety Convention and US regulatory practices.

The main purpose of the book is to provide written background material to the participants and to support lecturers of the training courses on Regulatory Control of Nuclear Power Plants. The idea is to present general practices recommended by the IAEA in its safety guidance as well as country specific examples how these general principles and requirements have been implemented in various countries. Lecturers can provide detailed information concerning their own countries and organizations but it is often difficult for them to provide as detailed knowledge on other countries and organizations. Therefore different examples are valuable for comparison.

The examples selected are representative, showing existing and functional practices and also provide a good selection of different practices adopted by different regulatory organizations. They reflect practices in large and small countries and regulatory bodies.  They do not follow any particular regulatory practice but try to offer several alternatives to be useful for many inspectors coming from different types of organizations.

The textbook has been compiled from the presentations provided during the training courses on Regulatory Control of Nuclear Power Plants from 1997 to 2001. The written presentations were collected from the lecturers and compiled before and during the consultants meetings from 16-20 November 1998 and 1-5 October 2001, in Vienna by K. Burkart, Germany, J. Libmann, France, C. Stoiber, United States of America, I. Aro, IAEA, C. Schober, IAEA.

The course was organized eight times in Europe: in Slovakia, Finland, the Czech Republic, Germany (four times) and the United Kingdom in 1994-2001 and two times in Asia: in Indonesia and in the Republic of Korea. Some of the lecturers have participated in several courses and are also the main contributors to the written text parts. Also several German lecturers have contributed in various regulatory fields providing German examples. The Gesellschaft für Anlagen und Reaktorsicherheit (GRS)mbH, Germany, Health and Safety Executive, United Kingdom, Institute for Protection and Nuclear Safety (IPSN), France, and Radiation and Nuclear Safety Authority (STUK), Finland, and the US Nuclear Regulatory Commission provided material support in the form of examples.
