Dongfang Electric Corporation and Électricité de France Sign Low-Pressure Diaphragm Supply Agreement

en.Wedoany.com Reported - Recently, Dongfang Electric International Corporation (hereinafter referred to as "Dongfang International"), a subsidiary of Dongfang Electric Corporation, officially signed a low-pressure diaphragm supply agreement for nuclear power steam turbines with Arabelle, a subsidiary of Électricité de France (EDF). Under the agreement, Dongfang Electric will serve as a key equipment supplier, providing core steam turbine low-pressure diaphragm components for the life extension and modernization technical transformation projects of EDF's pressurized water reactor (PWR) nuclear power units.

For over three decades, Dongfang Electric Corporation and Électricité de France have maintained close strategic collaboration in the field of civil nuclear energy. From early technology introduction and assimilation to jointly undertaking major engineering construction, the two sides have achieved fruitful industrial results. The formal conclusion of this supply agreement represents another key tangible outcome of the two parties' continuous deepening of exchanges and advancement of practical cooperation in recent years around global nuclear energy industrial chain and supply chain synergy. It marks the transformation of the strategic consensus formed between the two sides in the fields of nuclear power equipment manufacturing and aftermarket services into substantive engineering action, and will strongly support high-quality technical transformation and long-cycle safe and stable operation of Europe's in-service nuclear power units.

The low-pressure diaphragm, as a core flow passage component of the energy conversion system of nuclear power half-speed steam turbines, has its operating condition directly related to the thermal work efficiency and structural safety of the entire unit. This component is composed of a large number of high-precision stationary blades precisely assembled and arranged along the circumferential direction, forming a key channel that guides high-temperature and high-pressure saturated steam to expand and perform work. Due to exposure to complex fluid erosion and alternating thermal stress, it presents extremely demanding industrial technical thresholds in terms of wear-resistant special material forming, structural rigidity of large-diameter ring components, and high-tolerance precision machining. Leveraging its profound design and manufacturing heritage in the field of large million-kilowatt-class nuclear power steam turbine generator units, Dongfang Electric Corporation has continuously optimized precision CNC machining and welding assembly processes for high-end heavy energy equipment, fully demonstrating the high-end delivery strength of China's nuclear power equipment manufacturing system.

Looking to the future, Dongfang Electric Corporation will leverage the advantages of its "one core, two wings" industrial strategic layout, continuously consolidate and deepen practical collaboration with France's nuclear power industry, and work together to address multiple challenges including the global green and low-carbon energy transition and the reshaping of nuclear power supply chain resilience, advancing the China-France comprehensive strategic partnership steadily forward in the "new sixty-year journey" through mutual benefit and win-win cooperation.
