Fast assessment of the error in the neutron distribution in a large reactor in Monte Carlo calculations

Abstract

It is suggested that there is a close analogy between the statistical error of local characteristics in a Monte Carlo calculation of a large reactor and random deviations of the multiplication properties of these cells from a nominal value within technological tolerance limits. It is well-known that the latter result in global and strongly correlated deformations of the neutron field which are especially noticeable in large reactors. The scale of the deformations, or the statistical error, of the neutron field is determined by a formula obtained from an analysis of the influence of technological tolerances. Model Monte Carlo calculations confirm that this analogy is correct.
