Small Modular Nuclear Reactors (SMRs) are defined as nuclear power reactors with a maximum electrical output below 300MWe.They are generally considered to have distinct characteristics that make them different from conventional large reactors (LRs), such as modular design with pre-fabrication in offsite factories and the potential to deploy multiple reactors at the same site to form larger power plants. Many SMRs are also being designed as ‘integral’ units, where all key primary system components are...
