Abstract
This paper deals with the evaluation of tungsten temperature of divertor during external loss of coolant accident (Ex-LOCA) in connection with the safety design of nuclear fusion experimental reactor. The present result and the results of U.S.A. and EC are discussed in the conceptual design of International Thermonuclear Engineering Reactor (ITER), and reference LOCA temperature is recommended to be 700{+-}100degC for divertor, lasting 7 days. Corrosion depth of graphite tile of the first wall is evaluated during loss of vacuum accident (LOVA). The corrosion depth, duration time for the corrosion, generating heat, and volume of carbon monoxide are calculated when the carbon is attacked by oxygen in the air contained in the volume of the vacuum vessel. It is found that the results are not significant if fresh air does not continue to enter the vacuum vessel. (author).
