概要

• 論文の詳細を見る

• A direct search algorithm is applied to the optimization of fuel assembly allocation ;of BWR with particular consideration given to the nuclear model and the treatment of ;operating constraints. A simple expression is derived for evaluating the stuck rod margin, ;based on regression analysis of data obtained by three-dimensional full core analysis, and ;the expression is applied to optimization procedure.<BR>The practical applicability of the method is confirmed through trial computations for ;the second and equilibrium cycles of a medium-sized commercial BWR, with an examina-;tion based on various initial guesses and objective functions for radial power peaking.
