Collaboration. The youth program of the World Atomic Week forum in Moscow featured the first-ever grand finale of the Global HackAtom international student championship. The event brought together more than 50 winners of the national rounds from Russia and nine partner countries. The finale’s high point was the presentation of projects focused on space applications of advanced nuclear technologies. The winning team was TUPI Tech from Brazil, with a project dedicated to developing a modular nuclear reactor for space exploration. Second place went to the Tahu Sumedang team (Indonesia) for their concept of using nuclear technologies to regulate human circadian rhythms during interplanetary travel. Third place was awarded to the IsotopeX team (Hungary) for their project of a nuclear power source for a medical device designed to monitor an astronaut’s vital signs. Global HackAtom is an international student championship where participants tackle challenges based on real-world cases from the nuclear industry within a 24-hour timeframe. This year, its national rounds were held in 10 countries, uniting over 650 participants (more than 160 teams).
