Nuclear power

There are new uranium reactors that have the same safety features that thorium reactors provide. They require uranium 235 to be enriched to 5 to 20 percent as opposed to 4% used in conventional reactors. The higher enriched particles are very small, the size of caraway seed. They are encased in small ceramic spheres the size of a billiard ball. The case captures the unwanted radioactive elements while releasing the heat needed to run the reactor. This removes the long term storage problems associated with regular reactors. The reaction takes place at high temperature (1,500) F the same as thorium which means efficient transfer of heat from the reactor to the helium gas that surrounds the reactor vessel. This heated helium is then used to boil water to create the steam needed to run the turbines to create electric power. The fuel supply comes from two sources. First is to continue the enrichment process currently used from 4% to some higher level up to 20%. The second is to take nuclear bomb fuel which is 90% and blend it down to less than 20%. Much like thorium reactors these new units can be manufactured on an assembly line and shipped by truck to the use point. They can also use fuel created from the waste product currently stored at regular nuclear power plants. In essence these are small nuclear reactors using uranium that have all the advantages of small thorium reactors.
