Among the significant foreign activities of the company is its involvement in the international project of the European research reactor Jules Horowitz (JHR) in France. Through the design, construction, and delivery of hot cells for this reactor, we have positioned ourselves among several companies worldwide capable of manufacturing and delivering such demanding technologies. Currently, in collaboration with other members of the JHR consortium, we are also contributing to the preparation of experimental programs and tools for JHR. In doing so, we assist in creating conditions for the utilization of the reactor's capacities by the Czech Republic, considering the provided technologies through in-kind deliveries. Similarly, our company is involved in the preparation of the European Spallation Source (ESS) in Lund, Sweden, in a comparable manner.
