Analysis of Environmental Influence in Maximum Hypothetical Accident of CFBR-II Reactor

Scale of accident and data of radioelement on CFBR-II reactor are calculated and analyzed based on the principle used in its determination in the fast pulsed reactors in foreign countries. According to analysis of gas-dispersion mode, aerodynamic diffusion mode and source of individual effective dose, the individual effective dose of public and operator on the representative position in a conservative estimate is obtained. Compared with the national standards, it is not necessary to take emergency measurements such as for the public and operators to take iodine, shield and evacuate when maximum hypothetical accident does occurred.
