A containment building is a reinforced steel, concrete or lead structure enclosing a nuclear reactor. It is designed, in any emergency, to contain the escape of radioactive steam or gas to a maximum pressure in the range of 275 to 550 kPa (40 to 80 psi).
The Lungmen Nuclear Power Plant under construction (now halted) This table lists stations under construction stations without any reactor in service. Planned connection column indicates the connection of the first reactor, not thus whole capacity.
This is a list of all the commercial nuclear reactors in the world, sorted by country, with operational status. The list only includes civilian nuclear power reactors used to generate electricity for a power grid. All commercial nuclear reactors use nuclear fission. As of December 2024, there are 419 operable power reactors in the world, with a ...
A fission fragment reactor is a nuclear reactor that generates electricity by decelerating an ion beam of fission byproducts instead of using nuclear reactions to generate heat. By doing so, it bypasses the Carnot cycle and can achieve efficiencies of up to 90% instead of 40–45% attainable by efficient turbine-driven thermal reactors.
The world's first and only nuclear power plant that put Gen IV reactors into commercial use is Shidao Bay Nuclear Power Plant. The reactor is a high-temperature gas-cooled reactor, started its building process on September 21 2014, [75] started to generate power December 20, 2021, [76] and was put into commercial operation in December 12, 2023 ...
In October 2010, the South Texas Project announced that the Tokyo Electric Power Company (TEPCO) had entered into an agreement with Nuclear Innovation North America (a joint venture between the reactor manufacturer, Toshiba, and plant partner NRG Energy) which was the largest of the two stakeholders in the proposed reactors, to purchase an ...
But nuclear development did not stop. In China, for example, there were 13 nuclear reactors in 2011. There are now 55, with another 23 under construction.
