A number of neutronics of JNIR big uranium target are simulated towards the planning of experimental investigations aimed to the transmutation of radioactive waste. Integral data of the neutron yield and energy spectra are given for several homogeneous spallation targets which are planned to be used as insertions in uranium blanket. Combined spallation targets are also of interest, because it can help to obtain an optimal neutron energy spectrum for effective burning of long-lived fission products and minor-actinides. For this purpose, uranium-beryllium dual insertion was also considered and described in this work.
Изучение кинетики подкритических систем, управляемых ускорителями заряженных частиц высоких энергий, представляет большой интерес для решения проблем, связанных с трансмутацией радиоактивных отходов. В настоящей работе описаны результаты моделирования нейтронно-физических характеристик большой урановой мишени, на которой планируется проведение экспериментальных исследований, нацеленных на выжигание долгоживущих продуктов деления и минор-актинидов. The study of the kinetics of accelerator-driven subcritical systems is of great interest for solution of the problems related to the transmutation of radioactive waste. It is planned an experimental research aimed at burning of long-lived fission products and minor actinides on the big uranium target. The simulation of its neutronics is described in this paper. Ключевые слова: подкритические системы, управляемые ускорителями; мишень расщепления; нейтроннофизические характеристики; энергетические спектры.
