Future social situation analysis and road map of development of nuclear power technologies

In order to draw up the R and D principle of nuclear power plant, various factors affected on demand of atomic power were extracted, evaluated and analyzed. The results were arranged to road map of development of nuclear power technologies. A future model of nuclear power is made by Dynamic New Earth 21 (DNE21) model and System Dynamic (SD) model, when seven factors such as demand of electric power, environment load, location, economy, technology, social system and supply of non-electric power energies are considered to affect on the demand of nuclear power. Analysis of demand of nuclear power includes assumption conditions, amount of nuclear power generation and sensitivity analysis of factors. The countermeasures of factors were extracted and importance of them was listed. The development themes of technologies were extracted and evaluated. It evaluated demand of nuclear power, amount of wastes and resource consumption on the basis of LWR, but these amounts will change in the case of other reactors. (S.Y.)
