The issue of WWER-1000 spent fuel pool cooling in total blackout conditions is evaluated. A model of a spent fuel pool for MELCOR computer code is developed. Basic information about a spent fuel pool construction is shown. ...

In the paper the radionuclide contribution to heat release at dry storage of spent nuclear fuel (SNF) of WWER-1000 was researched. β- and γ-radiation from 60 of the most active fission products, and α-radiation from 20 ...

Designs and process flow sheets for production of nuclear fuel rod elements and assemblies TVS-ХD with disper-sion composition UO₂+Al are presented. The results of fuel rod thermal calculation applied to Kharkiv subcritical ...

SCALE software package has been used to model a ventilated concrete container for the dry storage of spent nuclear fuel. The methodology of calculations, which isused to substantiate the nuclear safety of dry storage, is ...

Non-oxide ceramics possess high physical-mechanical properties, corrosion and radiation resistance, which can be used as a protective materials for radioactive wastes disposal. The aim of the present study was the manufacturing ...

Neutron kinetics of nuclear burning wave in moving incompressible neutron-multiplying medium in the pres-ence of nuclear reactions is developed. A cylindrical reactor is considered, where the burning wave moves radially ...

Some issues of safety of the unique in Ukraine the Dry Spent Nuclear Fuel Storage Facility are highlighted. The analysis of temperature measurements of air, which cools storage containers of the spent nuclear fuel on the ...

It was found that increasing the surface concentration of iron atoms in zirconium alloys in the surface layer thickness up to 0.3 μm results to the formation of gradient structures. This process can help to optimize the ...

For fuel loading maintenance at Ukrainian nuclear power units, as well as to ensure the reactor unit economical and safe operation, it is necessary to have accurate and timely information on the energy release fields, ...
