Q

SMRs are defined as small nuclear reactors with a maximum output of x Megawatt electric (MWe) and can produce 7.2 million kWh per day. By comparison, large-size nuclear power plants have an output of over 1,000 MWe and can produce 24 million kWh per day. SMRs can vary in size from around x megawatts electric (MWe) up to x MWe and can use a range of possible coolants including , or , depending on the technology.

A

SMRs are defined as small nuclear reactors with a maximum output of 300 Megawatt electric (MWe) and can produce 7.2 million kWh per day. By comparison, large-size nuclear power plants have an output of over 1,000 MWe and can produce 24 million kWh per day. SMRs can vary in size from around 20 megawatts electric (MWe) up to 300 MWe and can use a range of possible coolants including light water, liquid metal or molten salt, depending on the technology.

Q

SMR is the generic term to name such kinds of reactors, but the ones based on technology are also often called advanced modular reactors (AMRs). They all use nuclear fission reactions to generate heat that can be used directly or for generating electricity.

SMRs comprise the latest technological features and safety advantages and many companies, and start-ups are looking into SMR projects.

SMRs are harnessing the operating experience from traditional large reactors, as well as the use of small-scale reactors in nuclear submarines and other nuclear-powered vessels, such as icebreakers.

SMRs have passive (inherent) safety systems, with a simpler design, a reactor core with lower core power and larger fractions of coolant. These altogether increase significantly the time allowed for operators to react in case of incidents or accidents.
