Report presents project for the construction of a low power integral system on the basis of the proton accelerator of energy 660 MeV and sub-critical MOX blanket with uranium-plutonium fuel. Installation includes sub-critical core with a nominal thermal power of 15-20 kW. Multiplication coefficient keff = 0.95 and the accelerator beam power of 0.75-1 kW. The experimental programme for SAD will ...

Cosmological variation of the fine structure constant α due to the evolution of a spatially homogeneous ultra-light scalar field (m ∼ H0) during the matter and Λ dominated eras is analyzed. Agreement of ∆α/α with the value suggested by recent observations of quasar absorption lines is obtained by adjusting a single parameter, the coupling of the scalar field to matter. Asymptotically α(t) in th...

issues. These include the material employed in the reactor walls, the cladding material for the fissile nuclear fuel, and the material used for retaining the fission products. In addition to long term resistance to irradiation, the materials used in a nuclear reactor must have excellent mechanical and corrosion properties in order to tolerate the thermal shocks as well as the high temperature a...

The contamination of Japan after the Fukushima accident has been investigated mainly for volatile fission products, but only sparsely for actinides such as plutonium. Only small releases of actinides were estimated in Fukushima. Plutonium is still omnipresent in the environment from previous atmospheric nuclear weapons tests. We investigated soil and plants sampled at different hot spots in Jap...

The study of fission yields has a major impact on the characterization and understanding process its applications. products have direct influence amount neutron poisons that limit fuel burnup evaluation decay heat reactor after shutdown. Fission yield represents synthesis experimental theoretical knowledge in order to perform best estimation mass independent product yields. Today, lack correlat...
