高温气冷堆超临界蒸汽动力循环电站研究

模块化高温气冷核反应堆是一种安全性好、可用于高效发电和提供高温工艺用热的先进核反应堆,是国际核能领域第4代核能系统中6种备选堆型之一。将模块化高温气冷堆技术与目前已经成熟的超临界蒸汽动力循环技术耦合,发电效率将达到45%以上,比目前在役的压水堆核电站效率(33%左右)高出30%以上。我国已经掌握了模块化高温气冷堆技术;通过引进、消化、吸收,也已经掌握了超临界蒸汽动力循环技术;具备条件研究建造高温气冷堆超临界蒸汽动力循环电站,使其成为世界上最早实现的超临界核电站。

Investigations on the Coupling of HTGR with Supercritical Steam Cycle

With its inherent safety and high temperature capability, the modular high temperature gas-cooled reactor (HTGR) has been taken as one of the six candidates for Generation IV innovative reactors. The HTGR supercritical (SC) steam cycle plant coupling the existing technologies of the current HTGR design with operational experiences of the SC fossil power plant (FPP) will achieve high cycle efficiency, 45% and above,which is 30% higher than that of the existing PWR plants (with net efficiency of 33%). The modular HTGR technologies are well mastered in China and the SC FPP technologies are also adopted in China through licensed production and cooperation. All required techniques are available to build the HTGR SC steam cycle plant, which will be the first innovative nuclear system in operation in the world.
