Premiers chiffres clés fin 2023
Baisse du nombre de mises en construction de réacteurs nucléaires
La Chine et la Russie conservent leur position de leaders. Le marché de niche des centrales nucléaires continue à être dominé par la Chine et la Russie. La première par le nombre de chantiers, la seconde par le nombre de projets mis en oeuvre au plan mondial. Au cours des quatre dernières années, il n’y a pas eu un seul début de construction de réacteur nucléaire dans le monde qui ne soit implanté en Chine ou mis oeuvre par la Russie. (…)

The first hosting the most construction sites, the second implementing the most projects globally. For the past four years, not a single construction start has been registered in the world that was not located in China or implemented by the Russian industry. Developments Over the Year 2023 At the beginning of 2023, nine reactors were scheduled to start up during the year in the world (…)
