NUCLEAR REACTOR CONTROL AND SIMULATION Russian patent published in 2015 - IPC G21C1/04 

Abstract RU 2549178 C2

FIELD: physics, nuclear.

SUBSTANCE: invention relates to travelling wave nuclear reactors. Determination of core section materials comprises determination of the amount of the main fissionable materials and the amount of substitute materials. Determination of microscopic cross-section of main material absorption and that of neighbour materials. Approximation of microscopic cross-section of absorption by neutron flow spectrum function and, additionally, by absorption microscopic cross-section function integral weighed by neutron flow spectrum.

EFFECT: simulation of optimum composition of travelling wave reactor core.
