The World Association of Nuclear Operators (WANO) is marking its 30 year anniversary today.

WANO was established in the aftermath of Chernobyl accident, which the organisation says, ended any illusions that the world's nuclear operators could work solely within the confines of their companies or countries.

In May 1989, leaders of every commercial nuclear reactor in the world set aside their competitive and regional differences and came together to create WANO. 

The organisaion's mission is to maximise the safety and reliability of nuclear plants worldwide by working together to assess, benchmark and improve performance through mutual support, exchange of information and emulation of best practices.

Today, WANO has centres around the world – in Atlanta, Hong Kong, London, Moscow and Tokyo –  and represents more than 120 members who operate more than 430 civil nuclear power reactors around the world.

"The journey towards excellence in nuclear safety and reliability is continuous, and although today is a special day for the organisation, WANO’s focus today remains as unswerving as it was at the historical inaugural meeting in Moscow in 1989," the organisation said.
