A steam generator (SG) comprises one high-pressure turbine and three low-pressure turbines. The upgrading work will be done at Unit 3 in FY27 (April 2027 to March 2028) and Unit 4 in FY28 (April 2028 to March 2029). Kyushu Electric said that the replacements would \u201cimprove reliability and generation efficiency.\u201d<\/p>\n
Kyushu Electric Power placed its order for the SG replacement work with Mitsubishi Heavy Industries (MHI), whose Takasago Machinery Works in Hyogo Prefecture will design, manufacture, and complete the work at the site. According to the company\u2019s announcement steam turbines to be delivered will include 54-inch blades that the company itself has designed and developed.<\/p>\n
As a PWR plant manufacturer, MHI has demonstrated its superior technological capabilities both domestically and internationally. Already, MHI has delivered four such units in Japan and five overseas. In January 2024, it finished the production of SGs for three units to be used by \u00c9lectricit\u00e9 de France S.A. (EDF) in France, and will eventually supply nine SGs to that company. The processing precision needed for the part was on the order of 0.01mm.<\/p>\n
Since entering service, Genkai-3 has operated for 30 years and Genkai-4 for 27 years. Genkai-3\u2019s long-term facility management plan is now being examined by the NRA as a requirement for the unit to continue operation beyond 30 years, under standards for aging reactors that will fully come into effect in June 2025 as part of a new bundle of legislation known collectively as the Green Transformation (GX) Decarbonization Power Supply Bill.<\/p>\n","protected":false},"excerpt":{"rendered":"
