Abstract:
1. A method of judging practical conditions for use of an ordered structure alloy under an irradiation environment, comprising: preparing an irradiated state diagram that expresses for the ordered structure alloy a relation of a degree of long range order S to a variable R of an irradiated state of the ordered structure alloy, related to a damage rate and an irradiation temperature, on basis of an evaluation formula related to an effect of irradiation on the degree of long range order of the ordered structure alloy under irradiation environments by using as parameters, a first threshold value S for irradiation conditions under which the ordered structure alloy is to be used, calculating an R-value, and corresponding to the R-value, finding an S-value, an S comparing the S-value, the S
