• This paper deals with the optimization of a nuclear reactor system with consideration of neutron flux uncertainty. Using the average and two kinds of variance of neutron flux which are obtained by means of modal analysis technique, the author has formulated the maximization of average power output under the condition to make the uncertainty of neutron flux as small as possible and presented Mode Optimization Technique for the optimization problem of a distributive system. Numerical results show that the optimal distribution of average neutron flux is not always flat when we consider the uncertainty of neutron flux as a loss of safety or reliability of a nuclear reactor. The author finally points out some problems concerning the performance index for this statistical optimization of a nuclear reactor system.
