Syllable breakdown

Dictionary meaning

a nuclear fission reactor with an electrical output typically below 300 megawatts, designed to be manufactured in a factory as standardised modular units and transported to site for installation, as opposed to the large bespoke reactors of conventional nuclear power plants that require extensive on-site construction; small modular reactors are promoted as a means of reducing the capital cost, construction risk, and financing complexity that has made conventional nuclear power economically difficult in liberalised electricity markets; designs include light water small modular reactors that use proven fuel and coolant technology, molten salt reactors, high-temperature gas-cooled reactors, and fast spectrum designs; numerous countries and private companies are pursuing small modular reactor development as part of low-carbon energy strategies
