Abstract
It is shown that accelerated high-dose irradiation with full instrumentation is useful for radiation materials science research in the high-flux SM research reactor core with an intermediate neutron spectrum. The concept for modifying the core to increase the irradiation volumes in the channels in the fuel part of the core is formulated. The modification is to be done in two stages. First, the reactivity losses due to an increase in the irradiation volumes must be compensated by increasing the uranium load in a fuel element without changing the dimensions and geometry of the element. At the second stage, a new fuel element based on weakly absorbing structural materials will be developed and the specific power release in the core will be increased.
