Nuclear Safety and Reliability

Nuclear safety is a multidisciplinary area, covering all activities from site selection for a future nuclear power plant, its development and project design, licensing, component manufacturing, construction, commissioning, commercial operation, and its final decommissioning and disposal of waste. The development of each of these areas is constantly supported by its scientific research infrastructure.

Centrum výzkumu Řež is conducting a number of research projects that have the ultimate aim to improve nuclear safety. Among the traditionally strong areas is materials science and related research focused on both the processes of ageing and degradation of vital components and systems of existing nuclear power plants, as well as the new generation of reactors, such as supercritical water reactors and high-temperature helium reactors. CVR also has unique expertise in the analysis of nuclear safety – particularly accident analyses in the licensing process. In this area it is involved in the further development and improvement of deterministic assessment of nuclear safety, and in particular, focusing on a best-estimate method with uncertainty evaluation, or, on the application of cfd codes (computational fluid dynamics).
