ABSTRACT
From the very start, the main lines of research into heavy-water reactors at Laboratory No. 3 were as follows:
- nuclear reactor theory; - experimental determination of physical constants necessary for the
reactor design; - physical and heat-engineering experiments; - nuclear fuel burnup and the accumulation of neptunium, plutonium
isotopes, and transplutonium elements in nuclear fuel; - optimization of the physical characteristics of the reactor; - problems of the reliable regulation and control of the reactor power. Particular attention was given to investigating the radiation stability of heavy
water and construction materials. The top-priority task of the laboratory was to provide an experimental basis for carrying out neutron physical experiments.
