Do you want to act for nuclear power and the climate? Help us by joining or becoming a volunteer!


Established in March 2018, Voices of Nuclear is an association of volunteers, employees and supporters of the French nuclear industry, with no economic, institutional, union or political ties.

The association, run by and for employees, aims to regain the pride in being players in an exceptional scientific and industrial sector and to re-establish facts about nuclear energy.


Myrto Tripathi has been the president and founder of the “Voix du Nuclear” association since its creation on March 20, 2018.

Board of directors

Members of the Voices of Nuclear Board of Directors are part of it in their personal capacity; their participation does not commit their home organization. The Board provides advice and a variety of perspectives.

The Board of Directors of the Voices is constituted so as to represent the whole spectrum of our society. The Board members on the one hand come from the nuclear industry, and therefore know its reality and the way of functioning, and also take the responsibility for it. On the other hand, the Board is composed of the wide range of everyday beneficiaries of nuclear energy – representatives of sectors linked to environment, climate, medicine, public health, workers, and many more other fields of application, all social categories, age and sex combined.

While the Board of Directors ensures that the values and commitments of the Voices are respected, it does not have decision-making power. The Executive Board, composed exclusively of volunteers, holds all of decision-making power.
