The Czech Technical University (ČVUT) in Prague is collaborating with Stellar Nuclear and UJP Prague to develop the Raven microreactor, which could serve as an energy source for spacecraft and bases on Mars and the Moon.

According to Radio Prague International, the first prototype of the reactor is expected to be unveiled by the consortium in the coming years.

Project leader Martin Ševeček from the Czech Technical University stated, "Integrating an energy source for propulsion and ground base into a single device represents a significant technological advancement compared to existing solutions from other countries that require separate systems. The Raven is compact, reliable, and optimized for long-term autonomous operation in extreme conditions."

He mentioned that this nuclear reactor could operate for many years, making it a unique energy source for extended space flights.

Ševeček added, "The development of a nuclear microreactor is essential for the colonization of our Solar System."

Experts believe that to ensure the reactor's safety and lightweight design, new technologies and materials must be developed.

The research teams involved in the project are already testing several of these innovations.

These include specialized nuclear fuel capable of withstanding temperatures up to 3000 degrees Celsius, lightweight metal foam for effective radiation shielding, and innovative heat exchangers that enhance efficiency and reduce the overall weight of the system.

The project also plans to utilize carbon dioxide from the Martian atmosphere as a heat transfer medium for surface applications.
