Radiological Safety Analysis for a Hypothetical Accident of a Generic VVER‐1000 Nuclear Power Plant

Science and Technology of Nuclear Installations, Volume 2020, Issue 1, 2020., 2020
Atmospheric dispersion modelling and radiological safety analysis have been performed for a postulated accident scenario of a generic VVER‐1000 nuclear power plant using the HotSpot Health Physics code. The total effective dose equivalent (TEDE), the respiratory time‐integrated air concentration, and the ground deposition concentration are calculated ...

The Choice of Nuclear Energy for Ghana as a Result of Development of Its Energy Production

Journal of Energy, Volume 2020, Issue 1, 2020., 2020
Ghana thought of nuclear energy early in the 1960s but has not been able to realize this dream of generating electricity from nuclear power. Ghana’s electricity generation dates back to the Gold Coast era where the main source of electricity supply (isolated diesel generators) was owned by industrial establishments, municipalities, and other ...

Assessment of the possibility for large-scale 238Pu production in a VVER-1000 power reactor

Nuclear Energy and Technology, 2023
The paper presents the estimates for the possibility for large-scale production of 238Pu in the core of a VVER-1000 power reactor. The Np-fraction of minor actinides extracted from transuranic radioactive waste is proposed to be used as the starting material. The irradiation device with NpO2 fuel elements is installed at the reactor core center.
