Description

About half of the nuclear power plants in Japan have been operating for more than 30 years. There is consequently an increased need for improvements in reliability and profitability as well as lifetime extension of existing nuclear power plants as a countermeasure against global warming. As a solution to these issues, Toshiba has developed the following technologies for existing nuclear power plants: (1) a performance-enhancing technology for steam turbines to prevent degradation due to aging, (2) various laser-based maintenance and repair technologies for inside reactor vessels, and (3) technologies to enhance power supply systems by reconstructing the entire system and renewing aging facilities.
