Fission/fusion

Much of the world s separated plutonium has been used for nuclear weapons (Table 1). It is probable that 5 kg or less of Pu is used in most of the fission, fusion, and thermonuclear-boosted fission weapons (2). Weapons-grade plutonium requires a content of >95 wt% Pu for maximum efficiency. Much plutonium does not have this purity.

Fusion energy offers a number of advantages over all other energy sources, including fission. Fusion reactors do not produce air pollutants that contribute to global warming or acid rain. The deuterium fuel they use is available in essentially unlimited supply from seawater, and tritium can be generated on-site as...

We are justly proud of great achievements of the twentieth century like the invention of particle-accelerators, control of nuclear fission, the potential control of fusion, and the transmutation of one element into another yet we discover that particle-accelerators, fission, fusion, and transmutation have been going on in the sun and stars for several billions of years. 

Describe the various ways In which nuclear energy may be used to generate electricity fission, fusion, and the breeder reactor. 

Nuclear fusion became important on Farth with the development of hydrogen bombs. A core of uranium or plutonium is used to initiate a fission reaction that raises the core s temperature to approximately 10 K, sufficient to cause fusion reactions between deuterium and tritium. In fusion bombs, LiD is used as Li reacts with fission neutrons to form tritium that then undergoes fusion with deuterium. It is estimated that approximately half the energy of a 50 megaton thermonuclear weapon comes from fusion and the other half from fission. Fusion reactions in these weapons also produce secondary fission since the high energy neutrons released in the fusion reactions make them very efficient in causing the fission of...
