Аннотация

The paper presents the results of numerical studies of nonstationary processes without feedback in a research reactor. The obtained results show a large degree of uncertainty of the calculated functionals depending on the parameters of the time, spatial, and energy grids. A brief description of the parallel version of the CTART4 code is given.
