Steam Generator
The steam generator produces steam. The steam generator separating the reactor system from the turbine system plays a crucial role in maintaining the reliability of the entire PWR plant. Since producing its first unit in 1970 for the Mihama Unit 2, Mitsubishi have continuously improved the design. More than 100 steam generators, including replacement units, have been manufactured and delivered.
