  The Small Modular Reactors (SMRs) are nuclear power reactors that have power level of 300 MWe or less and are designed in form of modular units. The Advanced SMRs (aSMR) are SMR with generation 4 design objectives. These reactors can be manufactured at a factory and transported by truck or rail to a nuclear power site for onsite installation. SMRs theoretically offer major advantages over traditional large nuclear power reactors such as minimum on-site construction, lower initial capital investment, better power scalability and siting flexibility, higher containment efficiency, enhanced safety and nuclear materials security. Some industry observers believe that SMRs are one solution for the four major challenges in creating nuclear energy facilities, which are costs, safety, waste, and proliferation. Still some others believe that SMRs may not be able to solve problems confronting nuclear power. This presentation assesses the technical characteristics of current SMR designs, which are mostly based on traditional LWR technology. The presentation then analyses the technical objectives and conceptual designs of aSMR which require lots of study and research, for both supply side and demand side. In order for aSMRs to be able to solve current problems confronting nuclear power, aSMR designs must simultaneously resolve the four major challenges without trading off among them. The design should be based on regulatory requirements with realistic technology-specific based on acceptance criteria and outcomes. Based on newest accepted conceptual designs of aSMR, research direction and challenges for the design and development of aSMR in the next 15 years will be presented and discussed.
