The prevalent advanced technology for conventional coal fired power generation at the moment is 600℃ class USC, which was developed in the 1980's. However, from the viewpoint of enhancing the plant efficiency and reducing the CO_2 emission, development steam turbines with a still higher steam conditions such as 700℃ class is vital. Development projects for 700℃ class USC technologies are underway in several countries including Japan. Advanced materials, such as Ni-based superalloy with high creep strength are vital for 700℃ class steam turbine. Certain constitutional design considerations, such as, efficient cooling design and/or welded constitution, will be constructive to achieve an economical design of 700℃ class steam turbine.
