By recycling the 3 He decay into the reactor, the fusion reactor does not require materials resistant to fast neutrons. Assuming complete tritium burn-up, the reduction in the fraction of fusion energy carried by neutrons would be only about 18%, so that the primary advantage of the D-D fuel cycle is that tritium breeding is not required.
Nuclear fusion–fission hybrid (hybrid nuclear power) is a proposed means of generating power by use of a combination of nuclear fusion and fission processes. The concept dates to the 1950s, and was briefly advocated by Hans Bethe during the 1970s, but largely remained unexplored until a revival of interest in 2009, due to the delays in the ...
Toroidal machines can be axially symmetric, like the tokamak and the reversed field pinch (RFP), or asymmetric, like the stellarator.The additional degree of freedom gained by giving up toroidal symmetry might ultimately be usable to produce better confinement, but the cost is complexity in the engineering, the theory, and the experimental diagnostics.
ITER (initially the International Thermonuclear Experimental Reactor, iter meaning "the way" or "the path" in Latin [2] [3] [4]) is an international nuclear fusion research and engineering megaproject aimed at creating energy through a fusion process similar to that of the Sun.
In 2017 the reactor achieved a stable 101.2-second steady-state high confinement plasma, setting a world record in long-pulse H-mode operation. [139] In 2018 MIT scientists formulated a theoretical means to remove the excess heat from compact nuclear fusion reactors via larger and longer divertors. [140]
The cross-sections of different fusion reactions. Nuclear fusion refers to reactions in which lighter nuclei are combined to become heavier nuclei. This process changes mass into energy which in turn may be captured to provide fusion power. Many types of atoms can be fused.
As of 2023, the Wendelstein 7-X reactor is the world's largest stellarator device. [3] After two successful operation phases ending in October 2018, the reactor was taken offline for upgrades. [4] [5] The upgrade completed in 2022. New fusion experiments in February 2023 demonstrated longer confinement and increased power. [6]
