CICRR - Czech International Centre of Research Reactors

The basic mission of the journal, Jaderná Energie/Jadrová Energia (Nuclear Energy), is to contribute to sustaining the high standards of nuclear safety when using nuclear energy for non-war purposes. The journal is published in the Czech and Slovak languages; selected scientific and technical articles, abstracts and annotations are also published in English. The journal is released four times per year, with 400 printed copies available, and in an electronic format that is available on this website, free of charge.

Journal Jaderná energie / Jadrová energia

Energy Well is a patented small modular reactor developed by the Research Center Řež. The project uses the latest knowledge in the field of salt smelting technologies that come from the Czech Republic, thanks to grants from the Ministry of Industry and Trade.

Energy well project

High Energy Load Czech Assembly is an experimental facility for cyclic high-heat-flux loading of components.

HELCZA

We work together

Involvement in national and international projects, associations and consortia provides the company with important links to knowledge platforms. The cooperation of individual members, both at the organisational and staff level, is a prerequisite for disseminating knowledge and promoting general awareness of current research topics in the energy sector.
