Fission reactors natural

The Canadian Deuterium Uranium reactor fissions with natural uranium, hence, no dependence on national or international fuel enrichment facilities that are needed to enrich uranium to about 3% U-235 to achieve criticality with light water moderation. [Pg.404]

The fear of accidents like Chernobyl, and the high cost of nuclear waste disposal, halted nuclear power plant construction in the United States m the 1980s, and in most ol the rest ol the world by the 1990s. Because nuclear fusion does not present the waste disposal problem of fission reactors, there is hope that fusion will be the primary energy source late in the twenty-first centuiy as the supplies of natural gas and petroleum dwindle. [Pg.481]

Energy development is international by its very nature. International cooperation in the sphere of energy will ensure faster progress and will make possible the realization of projects which no country could cope with on its own. Large-scale joint efforts between different nations, in particular, between East and West in the field of energy should be initiated. These efforts could include joint research on controlledfusion, and research and development on more inherently safe, as well as more reliable, fission reactors. [Pg.42]

Radioactivity, radioactive elements and nuclear reactors are found in nature. There are at least 14 natural fission reactors in the Oklo-Okelobon-do natural uranium formation in Gabon on the west coast of Africa. These fossil reactors had sufficient amounts of U-235 to allow chain reactions to... [Pg.217]
