Description
In nuclear power plants, a wide variety of pumps are used for heat transport in the power generation cycle, as well as for safety system equipment for injecting cooling water. Mitsubishi Heavy Industries, Ltd. (MHI) has been supplying various large-capacity pumps and high-pressure pumps for domestic PWR (pressurized water reactor) nuclear power plants, utilizing our design and manufacturing technology in which technical knowledge from the founding period of numerous domestic plants to the latest plants is brought together. This report presents the latest technology adopted in circulating water pumps and high-pressure multi-stage pumps aiming for increased power generation output, improved economic efficiency and the further improvement of safety and reliability in nuclear power plants in recent years, as well as newly developed maintenance tools.
