This should be much lower than the equivalent from fission energy.

Boosting can more than double the weapon's fission energy release.

The report says the "highest fission energy released was four-tenths of a pound."

Others, called fast breeder reactors, use fission energy neutrons directly.

Fissionable, non-fissile isotopes can be used as fission energy source even without a chain reaction.

Meanwhile, inside the exploding bomb, the free neutrons released by fission carry away about 3% of the initial fission energy.

A fission energy neutron that has slowed down but not yet reached thermal energies is called an epithermal neutron.

On the question of fission energy, our position is that we wish to see a phasing-out of nuclear power, although any decisions must be taken at national level.

The total prompt fission energy amounts to about 181 MeV, or 89% of the total energy which is eventually released by fission over time.

This results in 13 MeV (6.5% of the total fission energy) being deposited in the reactor core after any given fission reaction has occurred.

The safe management of fission energy depends in large part on a knowledge of the chemical properties of the actinide elements, many of which are man-made.

These neutrons have more energy than fission energy neutrons and are generated as secondary particles by particle accelerators or in the atmosphere from cosmic rays.

The entire fusion fuel canister would need to be enveloped by fission energy, to both compress and heat it, as with the booster charge in a boosted primary.

Denison recently purchased a number of projects from Fission Energy Corp - a uranium exploration company founded by Dev Randhawa.

In this type of fission, the product nuclei split the fission energy in three nearly equal parts and have kinetic energies of 60 MeV.

Beginning in the 1950s, atomic gardens were a part of Atoms for Peace, a program to develop "peaceful" uses of fission energy after WWII.

The fusion layer wrapped around the fission core could only moderately multiply the fission energy (modern Teller-Ulam designs can multiply it 30-fold).

They are named 'fission energy' or 'fast' neutrons to distinguish them from lower-energy thermal neutrons, and high-energy neutrons produced in cosmic showers or accelerators.

When a uranium nucleus fissions into two daughter nuclei fragments, about 0.1 percent of the mass of the uranium nucleus appears as the fission energy of 200 MeV.

If fusion energy could be exploited commercially, its proponents believe it could one day replace fossil fuels and nuclear fission energy, which is derived from the splitting of uranium or plutonium atoms.

Denison Mines also acquired the Fission Energy name and a new company, Fission Uranium Corp. was spun out by the Fission Energy management team.

Because U-238 is plentiful and has no critical mass, it can be added in almost unlimited quantities as a tamper around a fusion bomb, helping to contain the fusion reaction and contributing its own fission energy.

The Primer addressed fission energy, neutron production and capture, nuclear chain reactions, critical mass, tampers, predetonation, and three methods of assembling a bomb: gun assembly, implosion, and "autocatalytic methods," the one approach that turned out to be a dead end.

Fissionable fuel energy was said to be transferred to the propellant by radiation through a specially designed rigid-and coolable-container, similar to the way in which fission energy was transferred to hydrogen propellant in the NERVA design.

With regard to fission, I would like to re-state our commitment to renewable energy, although I accept that nuclear fission energy is now inevitable, given the high demand for energy and given that we still have few mass sources of energy available to us.
