Spanish research related to SMRs projects

Abstract

Small modular reactors (SMRs) are advanced nuclear reactors with a power capacity of up to 300 MW(e) per unit. SMRs encompass a variety of reactor technologies

including light water reactors, high temperature gas reactors, molten salt reactors, liquid metal cooled fast reactors, and heat pipe technology-based reactors. The

research and design of these diverse SMR types require a broad set of technological capabilities related to nuclear engineering and safety. Within this context, this

article attempts to assess the current state of research and technological progress achieved by the Spanish research groups and companies. The results reveal a

significant level of maturity among these groups and companies in various domains such as neutronic analysis, thermal hydraulic analysis, the improvement of

models related to severe accident scenarios and an active involvement in the design of novel SMR.
