The influence of non-uniformity of the neutron flux on the size of the "RHYTHM" type reactor plant

Although the work on research, improvement and design of the nuclear power plant has been carried out since the middle of the last century, in some points it still remains incomplete and many aspects require further studying. There is always a question of selecting the necessary materials for pipelines, fuel-element cladding, fuel assemblies, and the problem of which fuel and reactor type to choose. The selection of options always depends on the situation, the purpose of the installation, the location and the method of operation. Another important problem is the influence of the composition of various fuels and materials of the reactor core on the long-term operation of the nuclear steam generating plant at the full reactor power raising. Its economic benefit in comparison with other compositions should also be taken into consideration. It is necessary to find a balanced price-quality option.
