It was established in numerical experiments conducted at the Institute for Safety Research and Reactor Technologies (ISR-2) of the research center Forschungszentrum Julich (1998–1999) that thorium-plutonium fuel composition ensures due to the presence of anomaly in the dependence of resonance neutron absorption on the ratio of moderator volume to fuel volume the possibility to organize super-long duration of fuel residence in the cores of VVER-type reactors. Such possibility was demonstrated in the present study for high-temperature thorium-loaded reactor installation with 60 MW power. In this case the ratio of moderator volume to the volume of resonance absorber in the reactor core is within the interval of (45–60). It is specifically such type of low-power reactor installations that may constitute the basis of regional power generation in Russia.
