The DT rate peaks at a lower temperature (about 70 keV, or 800 million kelvin) and at a higher value than other reactions commonly considered for fusion energy. The reaction cross section (σ) is a measure of the probability of a fusion reaction as a function of the relative velocity of the two reactant nuclei. If the reactants have a ...
The Joint European Torus (JET) magnetic fusion experiment in 1991. Fusion power is a proposed form of power generation that would generate electricity by using heat from nuclear fusion reactions. In a fusion process, two lighter atomic nuclei combine to form a heavier nucleus, while releasing energy.
A fusion energy gain factor, usually expressed with the symbol Q, is the ratio of fusion power produced in a nuclear fusion reactor to the power required to maintain the plasma in steady state. The condition of Q = 1, when the power being released by the fusion reactions is equal to the required heating power, is referred to as breakeven, or in ...
U.S. scientists have achieved “ignition” — a fusion reaction that produced more energy than it took to create — a critical milestone for nuclear fusion and a step forward in the pursuit of ...
Lawrence Livermore achieved a net energy gain in a fusion experiment using lasers on Dec. 5, 2022. ... -U.S. scientists have achieved net energy gain in a fusion reaction for the second time since ...
Early this month, South Korea’s KFE (Korean Institute of Fusion Energy) announced it had sustained the kind of high temperatures that fusion reactions require—100 million degrees Celsius ...
Lawson criterion. The Lawson criterion is a figure of merit used in nuclear fusion research. It compares the rate of energy being generated by fusion reactions within the fusion fuel to the rate of energy losses to the environment. When the rate of production is higher than the rate of loss, the system will produce net energy.
Nuclear fusion breakthrough in California seen as milestone toward clean energy future. In a first, U.S. scientists have created “net energy” through a nuclear fusion reaction, the Department ...
