Nuclear reactor types (PWR, BWR, etc.)

Nuclear reactors generate electricity through controlled nuclear fission, where uranium atoms split to release energy. The two main types are Pressurized Water Reactors (PWR), which use high-pressure water to transfer heat without boiling, and Boiling Water Reactors (BWR), where water boils directly in the reactor to produce steam. PWRs keep water under pressure to prevent boiling, using a secondary loop to generate steam, while BWRs produce steam directly in the core. Both types involve complex safety systems and are designed to efficiently produce electricity with minimal emissions. Other types include heavy water reactors and fast breeders, each with unique features.
