Since the first nuclear reactor was built in 1942, scientists have been using nuclear energy. In the history of nuclear energy, tremendous advances in fission and reactor technology have been made and several new Generation III+ reactor systems have been constructed, such as AP 1000 and HPR 1000. Since the Generation IV reactor systems were proposed in 2002, six kinds of representative advanced reactor designs have been the priority of research and development. More recently, Generation IV+ nuclear systems have also been proposed. Nuclear energy has great potential for the future, but there are still a lot of challenges that need to be resolved. Therefore, an assessment of current technologies and a roadmap for future research paths are essential driving forces for the sustainable development of nuclear energy.

This Research Topic is focused on showcasing expert opinions and perspectives within the field of fission and reactor design. The collection aims to bring together experts from multidisciplinary fields to reflect on the past and highlight novel outcomes and future directions. It is hoped that this Research Topic will stimulate discussion in the field and encourage future collaborations.
