Role of Nuclear Energy in Environment, Economy and Energy Issues of the 21st century Green House Gas Emission Constraint Effects

Role and potentials of nuclear energy system in the energy options are discussed from the viewpoint of sustainable development with protecting from global warming by using the energy module structure of GRAPE model. The analysis with respect to carbon emission control and nuclear fissile transaction among regions indicates the need of coordinated further developments of energy conservation, renewable and nuclear energies, and rather drastic nuclear introduction in the presently developing world. The analysis also suggests the need of long-term planning and R&D efforts under the wisdom.
