3. DESCRIPTION OF PROGRAM OR FUNCTION
ChainSolver is designed for carrying out fast transmutation simulations of samples during irradiation in nuclear reactors. The code calculates a nuclide density time evolution with burnup, decay and buildup. The depression of a thermal neutrons flux, resonance self-shielding of isotopes during an irradiation, and the irradiation schedule (the schedule of the reactor work and rearrangement of an irradiated target in various positions) are taken into account. Such calculations allow to define the chosen mode of an irradiation and to calculate the expected outputs for both products and inevitable impurities. The main approximation used at calculation of transmutations is the assumption that the influence of changes in the irradiated material structure on characteristics of a reactor as a neutron source is insignificant. Resonance self-shielding factors are calculated in Intermediate Resonance approximation.
