The World Association of Nuclear Operators (WANO) is an international group of nuclear power plant operators, dedicated to nuclear safety.

It was formed in 1989, following the world’s worst nuclear disaster at Chernobyl (Ukraine), which was blamed on faulty design, wrong use of procedures and poor management control. As public confidence in the nuclear industry had been shaken, nuclear operators worldwide began to work together to prevent recurrences.

WANO promotes effective communication and open information sharing, via its five main programmes: Peer Review, Performance Analysis, Technical Support, Professional Development, and Corporate Communications. It is not a regulatory or advisory body, or a lobbyist for the industry.


"To maximise the safety and reliability of nuclear power plants worldwide by working together to assess, benchmark and improve performance through mutual support, exchange of information and emulation of best practice".[1] Its first chairman was Walter Marshall who had previously headed up the CEGB.[2] Dr Zack Pate was chairman from 1997-2002, its current chairman is Jacques Régaldo.

WANO Programmes[edit]

  • The Peer Review programme provides a critical assessment of station performance by an experienced team of global industry peers against nuclear industry standards of excellence as defined by WANO Performance Objectives and Criteria.[3]
  • The Performance Analysis programme collects, screens and analyses operating experience and performance data, providing members with lessons learnt and industry performance insight reports. Fundamental to its success is the willingness of WANO members to openly share operating experience and performance data for the benefit of nuclear operators worldwide.[4][5]
  • The Technical Support programme works with members to improve safety and reliability. Activities include technical support missions; new unit assistance; principles, guidelines and good practices; and plant of focus. Together, they help members learn from the experiences of their peers.[6]
  • The Training & Development programme provides assistance to WANO members through workshops, seminars and training. This includes new entrants as well as operating stations. Specific activities include workshops, seminars, training courses and leadership courses.[7]
  • The Corporate Communications programme ensures WANO's mission, vision and activities are shared with all internal and external audiences, including WANO members, industry vendors, new entrants, nations considering adding nuclear to their energy mix, other interested parties and the media. A variety of channels are used to promote access to WANO products and services.
