The NEA Small Modular Reactor (SMR) Strategy
Small modular reactors (SMRs) are a proposed class of nuclear fission reactors, smaller than conventional nuclear reactors, which can be built in one location (such as a factory), then shipped, commissioned, and operated at a separate site. The term SMR refers to the size, capacity and modular construction only, … Visa mer Economic factors of scale mean that nuclear reactors tend to be large, to such an extent that size itself becomes a limiting factor. The 1986 Chernobyl disaster and the 2011 Fukushima nuclear disaster caused … Visa mer SMRs are envisioned in multiple designs. Some are simplified versions of current reactors, others involve entirely new technologies. All … Visa mer One study reported that some types of SMR could produce more waste per unit of output than conventional reactors, in some cases more than 5x the Visa mer Small nuclear reactors, in comparison to conventional nuclear power generation plants, offer many advantages due to the flexibility of their modular construction. This flexibility in the modularity of a SMR system allows for additional units to be incrementally added … Visa mer Licensing Once the first unit of a given design is licensed, licensing subsequent units should be drastically … Visa mer Cooling Conventional reactors typically use water as a coolant. SMRs may use water, liquid metal, gas and molten salt as coolants. Coolant type is determined based on the reactor type, reactor design, and the chosen application. … Visa mer Some proposed SMRs use cooling systems that use thermoconvection – natural circulation – to eliminate cooling pumps that could break down. Convection can keep removing … Visa mer Webb30 maj 2024 · For this study, Krall analyzed the nuclear waste streams from three types of small modular reactors being developed by Toshiba, NuScale, and Terrestrial Energy. … WebbLower thermal power of the reactor core, compact architecture, and employment of passive concepts have the potential for enhanced safety and security compared to earlier designs and large commercial reactors. The passive safety systems are a very important safety feature in the SMR. Therefore, there is less reliance on active safety systems and ... he-man masters of the universe actors
