Transient neutron distribution solutions by compressed and real-time computer complexes

Abstract

Core transient neutron flux distribution currently constitutes one of the most intensively investigated phenomena in nuclear technology. Independently, nuclear physicists and system analysts attempt to develop solutions to the problem. The arsenal of mathematical tools presently available to them covers most of the spectrum ranging from precise multigroup digital computations to adiabatic core analog analysis. The former involve a series of steady state or quasi-steady state situations, hence are not acceptable to the transient analyst. The latter are too inadequate for detailed safeguard or control analysis, thus forcing the designer to increase his conservative margin.
