The AP1000 is a type of nuclear power reactor designed by Westinghouse Electric Company. It is a pressurized water reactor (PWR) that features advanced safety systems and a modular design, allowing for easier construction and maintenance. The AP1000 is known for its passive safety features, which can operate without external power or human intervention in case of an emergency. This reactor has a net electrical output of approximately 1,100 megawatts, making it suitable for large-scale energy production. The AP1000 is part of a broader effort to develop safer and more efficient nuclear energy technologies, contributing to the global energy mix and reducing reliance on fossil fuels.
