Examination of Stochastic and Deterministic Perturbations in Reactor Physics

摘要

The general solution of the perturbed diffusion equation in case of localized random perturbation is discussed in details. The autocovariance function of the flux perturbation and the reaction rate have been calculated by Green-function technique, and the algorithm is tested with some special analytic solutions. The reactivity and the variance of reactivity in cases of different perturbations has been determined numerically.
