Nuclear energy: Western nations ‘too optimistic’ on nuclear, warns engineering chief

| Western countries mishandle nuclear energy projects by failing to plan and trying to complete them too fast, the head of Atkins Realis, the biggest maker of reactors that run on natural uranium, has warned ahead of the first global nuclear summit this week.

Atkins Realis produces the only type of reactor that does not require enriched uranium, of which Russia is the biggest exporter. Its CANDU reactors are in demand as western countries seek to reduce their reliance on Russia for energy following the country’s full-scale invasion of Ukraine. Since 1990, China has built 55 nuclear plants. It has 22 under construction and more than 70 in the planning phase, and is building up exports of nuclear technology.

Heavy water absorbs fewer neutrons than regular water, leaving more of them free to collide with uranium atoms to trigger the fission reaction that releases atomic energy.
