Small Modular Reactor - an overview ScienceDirect Topics

Small modular reactors (SMRs) encompass a large number of technologies at different stages of development. A key challenge for SMR stakeholders is the evaluation of SMR competitiveness with respect to large reactors (LRs). SMRs are usually considered less competitive than LRs because of a misguided application of the economy of scale principle.
