How small modular nuclear reactors work and are they safe for Singapore?

Small modular reactors (SMRs) are advanced nuclear reactors up to 300MW capacity offering benefits such as smaller size, enhanced passive safety systems, and the potential for deployment closer to populated or industrial sites. Several SMR types—water-cooled, high-temperature gas-cooled, and molten salt reactors—are at various stages of commercial operation and development, with key safety features and operational characteristics explained, highlighting emerging global deployments including Russia, China, and the US.
