On May 15, 1989, in Moscow the WANO inaugural conference was held, officially announcing the establishment of the World Association of Nuclear Operators (WANO).

The main idea of the organization was to unite the efforts of operators (NPP) to maximize the safety and reliability of operating nuclear power plants worldwide. Today WANO is unique in being a truly international organization for which there are no political barriers and interests.

The members of the Association cooperate in the programs of regional centers located in Moscow (Moscow Center), Paris (Paris Center), Atlanta (Atlanta Center) and Tokyo (Tokyo Center). The Governing Board is in London.

The Moscow Center unites the nuclear power plants and operating organizations of Armenia, Belarus, Bulgaria, Hungary, India, Iran, China, Lithuania, Russia, Slovakia, Ukraine, Finland and the Czech Republic.

WANO performs its tasks on the basis of a voluntary exchange of information on the events occurring at the nuclear power plants, comparison of results achieved, peer reviews and operational experience exchange. At the same time, the independence of the members, their voluntary participation in the Association programs, equal partnership, mutual support and, what is the most important, the non-disclosure of the transmitted information remain its unbreakable fundamental principles.

The past years have proved the fruitfulness of the idea of establishing the Association and confirmed the correctness of the goals set for it. The implementation of WANO programs, a wide exchange of the nuclear power plants specialists allowed solving actual tasks to improve the safety level of the nuclear power plants worldwide in informal surroundings.


WANO Organizational Chart

The World Governing Board performs the overall management and determines the strategy of WANO. It consists of an elected Chairman and two representatives from each Regional Governing Board. The directors of the Centers are also present at the Governing Board meetings.

The WANO Membership is carried out through one or more regional centers (RC) located in Atlanta, Moscow, Paris and Tokyo.

The WANO office in London coordinates the work of the centers. The RCs comply with the Governing Board decisions and implement the WANO programs. The most part of the RC work involves the collection, systematization and analysis of WANO information on international operating experience, distribution of this information to members, as well as continuous consideration of the members needs for further development of the Association programs.

Each RC is headed by a Director and it is staffed by highly qualified personnel, seconded from member organizations. Rotational specialists working in the WANO centers have knowledge of specific technologies and operating culture adopted in their country. Upon completion of the work, they bring to their organizations the experience gained during their work at WANO and understanding of the operational practices at other nuclear power plants worldwide.

Once in two years, senior managers hold the WANO Biennial General Meeting to analyze the activities of WANO and identify their goals and objectives for the future. At the Biennial General Meeting the President of WANO is elected for a two-year term. The WANO Chairman is elected for a two-year term with a possible term extension.

WANO main programs

1. Operating experience

(operating experience information exchange)

This program allows members to use the operating experience of other nuclear power plants. In particular, the program informs members on the events that occurred at other nuclear power plants, and allows them to take appropriate measures to prevent the recurrence of similar events at their sites. Within the framework of the program, the members provide information on the events that occurred at their specific plants. The openness and fidelity of the event reports bring undoubted benefits to other operators worldwide. Sometimes this program is called the exchange of event reports.

2. Peer reviews

The purpose of the program is to enable the members to compare the operation of their plants with the best international practices through a deep and objective analysis of the operation by an independent group of experts from other organizations. The peer review conducted at the request of the plant is carried out by an international group consisting of experts from other members. The team checks the work of the plant in key areas in accordance with specific tasks and criteria for the plant operation. The WANO peer reviews allow WANO members to study and exchange the best world achievements in the area of safety and reliability of NPPs operation, and, consequently, improve the operation of their specific plants.

3. Professional and technical development
  • Working meetings
  • Workshops
  • Expert meetings
  • Training courses
  • Conferences

The purpose of the "Professional and Technical Development" program is to help WANO-MC members to improve their operational performance, reduce the number of failures and train personnel of nuclear power plants/ utilities, including the Leadership issues. The events conducted provide an opportunity for the NPP personnel to share information with the aim of expanding their professional knowledge, ideas for improving the safety and reliability of nuclear power plants, and comparing the results of operation, focusing on the experience of the best nuclear power plants.

4. Technical support and exchange
  • Technical information exchange

    Exchange of technical information by means of the WANO electronic communications system: the WANO Web site provides the opportunity for direct exchange of technical information between the members on the issues related to the NPPs operation and obtaining information on the best practices of the WANO activities.

  • Member Support Missions

    The Member support missions help the WANO members to find solutions for existing problems that they can not eliminate on their own, or to find ways to effectively improve a process in a field-proven way. The implementation of the MSM helps strengthening the links between the WANO members aimed at providing practical special-purposed assistance and support.

  • Operational performance (indicators)

    The "NPP Operational Performance" program is aimed at the exchange of information on the operating experience of the nuclear power plants through the collection and distribution of the data on the NPPs operation and identification of trends in nine key indicators. These targets are a partial, but very important and useful assessment of the quality of nuclear power plant management in general.

    This is one of the most important programs in the area of maximizing the reliability and safety of nuclear power plants. This program is constantly being improved from two sides - both from the WANO organizational structures, and from the NPPs themselves.

  • Exchange visits
  • Good practices
5. Communications

Compass is a long-term effective plan aimed at maximizing the safety and reliability of nuclear power plants worldwide, introducing higher production standards in the industry, improving the operational nuclear safety of the industrial nuclear power engineering.
