Fission or Fusion                  I think that right now, fission is the only way that we can get more energy out of a nuclear reaction than we put in. First, the energy per fission is very large. In practical units, the fission of 1 kg (2.2 lb) of uranium-235 releases 18.7 million kilowatt-hours as heat. Second, the fission process initiated by the absorption of one neutron in uranium-235 releases about 2.5 neutrons, on the average, from the split nuclei. The …showed first 75 words of 1275 total…

…showed last 75 words of 1275 total…the amount of fuel in the system is very small, and waste products much less radioactive and simpler to handle than those from fission systems.         I conclude, that even though fusion is much better, cleaner, and safer, than fission, we do not have the knowledge of how to create and contain the energy realesed in a fusion reaction. So, until we do, fission is the only way we can use the atom to create power.
