Abstract

In the last decades, taking into account the operational experience of fission nuclear reactors, the nuclear international technical community started the development of advanced reactor designs in order to satisfy the demand of the people to improve the safety of NPPs and to take into consideration the industry needs to improve the economic efficiency and reduce the capital costs of nuclear power technology. In this framework Small Modular Reactors (SMR) adopting light water as coolant, taking advantage of the experience developed in current larger scale LWR, can bring advantages in terms of increasing “inherent safety” due to the integral type configuration, lower nominal power, and the adoption of passive mitigation strategy. Starting from some of the research activities on code applications developed by the authors along the last decade, and available in the public scientific literature, the target of this paper is to give some insights and recommendations for the future development of new research activities, in national and international frameworks, in relation to thermal hydraulics of SMRs.
