In February of this year, the Ministry of Science and ICT launched a call for proposals for the Global TOP Strategic Research Groups project with the slogan “Bold Challenges from Research Institutes, Innovative Steps Together.” The Global TOP Strategic Research Groups initiative aims to establish an open collaborative framework focused on national missions that transcends the boundaries of research institutes, supporting them to achieve significant outcomes befitting national research organizations. This feature aims to briefly introduce the research background and goals of one of the five selected strategic research groups: the “Development of an SMR Virtual Reactor Platform.” This initiative, led by the Korea Atomic Energy Research Institute (KAERI), the Korea Institute of Science and Technology Information (KISTI), and the Electronics and Telecommunications Research Institute (ETRI), will be conducted over five years, starting from June 2024.
