Water at 155 bar circulates through reactor core, absorbing fission heat without boiling.
High-pressure coolant transfers heat via steam generators, boiling lower-pressure water to drive turbines.
Double containment, passive cooling systems and redundant safety systems prevent core damage in accidents.
Off-site fabricated components like reactor vessels assemble on-site with local infrastructure.
