The Role of Small Modular Reactors in the Energy Transition

Small Modular Reactors (SMRs) are an advanced class of nuclear reactors, featuring power generation capacities that span from less than 30 MWe to over 300 MWe. A comprehensive report from NITI Aayog delves into several critical aspects regarding SMRs in the context of the ongoing energy transition. It examines the evolution of SMR technology, the readiness of supply chains, efforts towards harmonizing SMR regulations, the international licensing process, and preparations for international safeguards. Additionally, the report emphasizes the necessity to minimize risks associated with SMR projects to attract private sector investments. Notably, the report underscores that SMRs have risen as the favored choice in nuclear energy when compared to larger reactors, primarily due to their lower inventory of nuclear material per reactor, streamlined fabrication through standardization, rapid deployment capabilities even in challenging locations, and the ability to manage capital expenditures in stages by incorporating successive SMR modules.
