[13] The term "tokamak" was coined in 1957 [14] by Igor Golovin, a student of academician Igor Kurchatov.It originally sounded like "tokamag" ("токамаг") — an acronym of the words "toroidal chamber magnetic" ("тороидальная камера магнитная"), but Natan Yavlinsky, the author of the first toroidal system, proposed replacing "-mag" with "-mak" for euphony.

Fusion reactors are not subject to catastrophic meltdown. [122] It requires precise and controlled temperature, pressure and magnetic field parameters to produce net energy, and any damage or loss of required control would rapidly quench the reaction. [123] Fusion reactors operate with seconds or even microseconds worth of fuel at any moment.
Commercial light-water nuclear reactors, the most prevalent power reactors in the world, use nuclear fuel containing uranium enriched to 3 to 5% U-235 while the leftover is U-238. [22] [23] Each fusion event in the D-T fusion reactor gives off an alpha particle and a fast neutron with around 14 MeV of kinetic energy
RBMK reactor fuel rod holder 1 – distancing armature; 2 – fuel rods shell; 3 – fuel tablets. RBMK reactor fuel rod holder Uranium fuel pellets, fuel tubes, distancing armature, graphite bricks. The fuel pellets are made of uranium dioxide powder, sintered with a suitable binder into pellets 11.5 mm in diameter and 15 mm long.
[1] [2] [3] The project is a proposed DEMO-class successor device to the ITER tokamak proof-of-concept of a fusion plant, the most advanced tokamak fusion reactor to date, which is scheduled to achieve a 'burning plasma' in 2035. STEP aims to produce net electricity from fusion on a timescale of 2040.
Pool type sodium-cooled fast reactor (SFR) A sodium-cooled fast reactor is a fast neutron reactor cooled by liquid sodium.. The initials SFR in particular refer to two Generation IV reactor proposals, one based on existing liquid metal cooled reactor (LMFR) technology using mixed oxide fuel (MOX), and one based on the metal-fueled integral fast reactor.
Billet of enriched uranium, a fissile material. In nuclear engineering, fissile material is material that can undergo nuclear fission when struck by a neutron of low energy. [1]
EGP is a Russian acronym but translated into English it stands for Power Heterogenous Loop reactor. [1] It is the world's smallest running commercial nuclear reactor, however smaller reactors are currently in development. [2] The EGP-6 reactors are the only reactors to be built on permafrost. [3]
