摘要
在压水堆环形燃料元件基础上,提出了一种新型适用于超临界水冷堆(SCWR)的环形元件。该环形元件具有大几何尺寸、采用UO2颗粒燃料、内包壳表面涂隔热层等特点。利用163盒由61个改进型环形元件及组件盒构成的六角形燃料组件,设计了百万千瓦环形元件超临界水冷堆CSR1000A,并给出了卸料燃耗、冷却剂出口温度及最大燃料包壳温度等关键参数。
On the basis of the annular fuel for PWR, a new type annular fuel for SCWR has been designed in this paper, which has bigger size than that of PWRs, adopts UOzparticles instead of fuel pellets and coats heat-barrier material on the surface of the inner cladding. Then a new 1000MWe SCWR design concept CSR1000A has been developed, whose core consists of 163 hexagonal fuel assemblies that are made up with 61 new annular fuels and assembly box. After CSR1000A core evaluation, these core key parameters such as discharge burnup, coolant averaged outlet temperature and maximum fuel cladding temperature are presented.
