许多国家正在大力发展压水堆高燃耗燃料,其批平均目标卸料燃耗能够达到5.0—5.5万兆瓦天/吨铀,因此显著地提高了铀利用率。高燃耗燃料即将陆续取代现行的燃料,这标志着压水堆燃料的更新换代。本文简要介绍高燃耗燃料的设计特点、燃料管理、经济效益、发展计划及发展前景等。
Many countries are making great efforts to develop PWR fuel with high fuel consumption. The average target discharge fuel burn rate can reach 5.0-5.5 MWh / t of uranium, thus significantly increasing uranium utilization rate. High-burn fuel will soon replace the existing fuel, which marks the pressurized water reactor fuel replacement. This article gives a brief introduction of the design features of high fuel consumption fuels, fuel management, economic benefits, development plans and development prospects.
