  2. Nuclear meltdown - Wikipedia

    en.wikipedia.org/wiki/Nuclear_meltdown

    A nuclear meltdown (core meltdown, core melt accident, meltdown or partial core melt [2]) is a severe nuclear reactor accident that results in core damage from overheating. The term nuclear meltdown is not officially defined by the International Atomic Energy Agency [3] or by the United States Nuclear Regulatory Commission. [4]

  3. Fusion power - Wikipedia

    en.wikipedia.org/wiki/Fusion_power

    Fusion reactors are not subject to catastrophic meltdown. [121] 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. [122] Fusion reactors operate with seconds or even microseconds worth of fuel at any moment.

  4. Core damage frequency - Wikipedia

    en.wikipedia.org/wiki/Core_damage_frequency

    Of these 582 reactors, 11 have suffered from serious core damage. [6] This historical data results in a 1954 to 2011 era average accident rate of 1 in every 1,309 reactor years (7.6 × 10 −4 per reactor year CDF). In five of these accidents, the damage was light enough that the reactor was repaired and restarted.

  6. Nuclear fusion - Wikipedia

    en.wikipedia.org/wiki/Nuclear_fusion

    The plasma tends to expand immediately and some force is necessary to act against it. This force can take one of three forms: gravitation in stars, magnetic forces in magnetic confinement fusion reactors, or inertial as the fusion reaction may occur before the plasma starts to expand, so the plasma's inertia is keeping the material together.

  7. Nuclear fusion–fission hybrid - Wikipedia

    en.wikipedia.org/wiki/Nuclear_fusion–fission...

    Hybrid nuclear fusion–fission (hybrid nuclear power) is a proposed means of generating power by use of a combination of nuclear fusion and fission processes. The basic idea is to use high-energy fast neutrons from a fusion reactor to trigger fission in non-fissile fuels like U-238 or Th-232. Each neutron can trigger several fission events ...

    The world's first nuclear reactor meltdown was the NRX reactor at Chalk River Laboratories, Ontario, Canada in 1952. [22] The worst nuclear accident to date is the Chernobyl disaster which occurred in 1986 in the Ukrainian SSR, now Ukraine. The accident killed approximately 30 people directly [23] and damaged approximately $7 billion of property.
