Why join WANO?

WANO members are affiliated with one or more Regional Centre (Atlanta, Moscow, Paris and Tokyo) based on the centre’s location or particular expertise. In addition to tailored support from the Regional Centres, all members have access to the following resources:

  • WANO member website: A comprehensive, member-only archive of  reports and information about nuclear plant safety across the world.

  • Operating experience: Through the website, members have access to information about events that have occurred at other plants. Information sharing between members allows plants to learn from each other’s mistakes and ensure they are not repeated elsewhere.  For more information visit the operating experience programme.

  • Peer review system: Each member receives a peer review every six years – moving to every four years after October 2015. Using an international team made up of both WANO and industry experts, peer review teams identify areas for improvement, which are outlined in a candid report presented to the member’s senior management. Good practices and strengths are also identified and shared with other members. For more information visit the peer review programme .

  • Technical support and exchange: WANO also offers its members support in targeting specific issues or problems. These tools include Guidelines and Good Practices, Performance Indicators, Technical Support Missions and Operator Exchanges. For more information visit the techn​ical support and exchange .

  • Professional and technical development: Plant safety starts with plant staff. This programme focuses on workshops, conferences, seminars, expert meetings and training courses that help develop professionals in the nuclear industry. For more information visit the professional and technical development programme.

Who qualifies for membership?

Any operator or owner of a nuclear power plant or nuclear fuel reprocessing facility for peaceful purposes and any organisation of nuclear power plant operators that has an important impact on nuclear safety can apply for membership in WANO in one of three categories. Multiple categories of membership are established based on participation, representation and influence over nuclear safety.

The WANO Articles of Association state that admission is subject to the discretion of the WANO Governing Board. WANO membership is voluntary and once an application has been approved, all members must follow the nine membership obligations, outlined in the WANO Charter and detailed in a WANO policy document.

If you are unsure about whether your organisation qualifies for membership, please use our decision-Tree.pdf.

How does the application process work?

The prospective member will work with the appropriate WANO director to complete an application form and a confidentiality undertaking. Once completed, a project plan will be drawn up to describe the planned interactions between WANO and the new member. This information, along with any other relevant details (for example, for new entrants with plants under construction, detailed plans should be submitted) will be supplied to WANO London before being presented to the WANO Governing Board.

WANO’s membership is comprised of nuclear plant operators. However, in certain circumstances other organisations that impact nuclear safety may be able to receive certain WANO services or products. Upon reaching an agreement with WANO, such organisations must complete a confidentiality undertaking.

Membership fees

Organisations approved for membership pay two fees:

1. To the London Office for general services

2. To their affiliated Regional Centre for specific services

Fees are based on a formula that considers the total number Category 1 members, the number of units operated and the overall electric production of the member.
