Scientists from the Department of Energy have nailed down the best shapes of waves to stabilize tokamak reactors. Tokamaks are subject to accumulating magnetic disruptions that scientists are working to control. In a model, these researchers found they can change up the beams that target the disruptions.
Q. What are the conditions required for nuclear fusion in the sun?
Fusion requires temperatures of about 100 million Kelvin (approximately six times hotter than the sun’s core). At these temperatures, hydrogen is a plasma, not a gas. Plasma is a high-energy state of matter in which all the electrons are stripped from atoms and move freely about.

Q. What conditions are required for fission and fusion to occur?
Conditions: Critical mass of the substance and high-speed neutrons are required. High density, high temperature environment is required.
Q. What conditions are needed for nuclear fission to occur?
High density, high temperature environment is required. Energy Requirement: Takes little energy to split two atoms in a fission reaction. Extremely high energy is required to bring two or more protons close enough that nuclear forces overcome their electrostatic repulsion.
Q. What is the main problem with tokamak?
The stored thermal and magnetic energy in the hot plasma can lead to plasma instabilities and loss of plasma confinement, i.e., plasma disruptions1. Loss of plasma confinement is a serious issue in tokamak devices that threatens successful operation of the tokamak designs.
Q. How does tokamak not melt?
Researchers had hoped that melting might be avoided by injecting noble gases into the plasma—a superheated state of matter that makes up 99% of the visible universe. A tokamak uses strong magnetic fields to confine a plasma that is heated above 200 million ℃, maximizing the efficiency of hydrogen isotope fusion.
Q. What is true about cold fusion?
“Cold fusion claims to release measurable energy from fusion reactions at or near room temperature when deuterium is dissolved in a solid, usually palladium metal. The cathodic reaction liberates unbound atoms of deuterium (D), which enter palladium much more rapidly than do deuterium molecules.
Q. What best describes forms in nuclear fusion two smaller more stable nuclei?
Nuclear Fusion: When two small atomic nuclei fuse together to form one larger atomic nucleus. During this process a lot of energy is released which means product formed will be stable. For example: Deuterium-Deuterium fusion leads to the formation of helium isotope.
