A Reactor Pressure Vessel (RPV) is a critical component in nuclear power plants. It houses the nuclear reactor core, where the fission process occurs. The RPV is designed to withstand high pressure and temperature, ensuring the safe containment of radioactive materials during operation. The RPV is typically made of thick steel to provide structural integrity and safety. It is equipped with various systems, including cooling and control mechanisms, to maintain optimal conditions. Proper maintenance and monitoring of the RPV are essential to prevent leaks and ensure the safety of the surrounding environment and personnel.
