How do we get energy from nuclear fusion?
In a fusion reaction, two light nuclei merge to form a single heavier nucleus. The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original nuclei. The leftover mass becomes energy.
What is NIF and how does it generate fusion energy?
NIF uses lasers to heat and compress a small amount of hydrogen fuel with the goal of inducing nuclear fusion reactions. At these temperatures, fusion processes occur very rapidly, before the energy generated in the fuel causes it to explode outward as well.
How does a confinement fusion reactor work?
Magnetic confinement fusion is an approach to generate thermonuclear fusion power that uses magnetic fields to confine fusion fuel in the form of a plasma. Fusion reactions combine light atomic nuclei such as hydrogen to form heavier ones such as helium, producing energy.
How is fusion energy converted to electricity?
Nuclear fusion power creates very fast-moving electrically charged particles….Heat engines
- The kinetic energy of the fusion products is converted into heat when they strike and penetrate the walls of the reactor.
- The heat in the shielding is converted into mechanical power through the use of a heat engine.
In what form is the energy of nuclear fusion released?
The fusion of lighter elements in stars releases energy and the mass that always accompanies it. For example, in the fusion of two hydrogen nuclei to form helium, 0.645\% of the mass is carried away in the form of kinetic energy of an alpha particle or other forms of energy, such as electromagnetic radiation.
Why is magnetic confinement being used in fusion research?
In a fusion reactor, very strong magnets are used to confine plasma within a vacuum vessel – with the goals of high plasma temperature, minimal thermal losses, high ion density, and a prolonged period of energy production.
