However, as part of making fusion weapons, some countries develop "boosted" fission bombs which use a small amount of fusion to boost the fission process, releasing more energy.
Niels Bohr, who won the Nobel prize for physics in 1921, also came to the conclusion that "nuclear fission bombs were not feasible." The stumbling block for them was the tiny amount of unstable Uranium 235 atoms.
Uranium-235 represents about 0.7% of naturally occurring uranium and can be separated for use in fission bombs. Plutonium-239 can also be used in fission bombs and is produced in nuclear power reactors from natural uranium.
