Generation II reactors were more reliable and efficient than their predecessors. However, their safety systems required external power and human intervention to operate effectively. Many of the reactors currently in use worldwide fall into this category.
3. Generation III and III+:
These reactors represent a significant improvement in safety and efficiency. They use passive safety systems that can automatically shut down the reactor without human intervention. Examples include the AP1000 and EPR reactors. Generation III+ reactors have longer fuel cycles and produce less radioactive waste, making them more environmentally friendly.
4. Generation IV:
Generation IV reactors are the reactors of the future. They include designs such as High-Temperature Gas-Cooled Reactors (HTGRs) and Fast Breeder Reactors (FBRs), which are not only safer but also more sustainable. These reactors are designed to maximize fuel use and minimize radioactive waste. A prime example is China’s Shidaowan HTGR, which went into commercial operation in 2023【Source: National Energy Administration (China)】.
