双面冷却环形燃料元件的几何尺寸优化
Geometric Size Optimization of Dual-cooled Annular Fuel Element
摘要
Abstract
Based on the design of dual‐cooled annular fuel elements ,relevant mathemati‐cal and physical models were established to calculate the flow distribution ,temperature field distribution and distribution of radial maximum fuel temperature positions along the axial direction ,and a thermal‐hydraulic calculation code was developed .Three eval‐uation indexes were independently proposed to evaluate geometric designs of dual‐cooled annular fuel elements ,and the ranges of optimal element sizes were obtained .Calcula‐tion results show that the optimized dual‐cooled annular fuel element presents good thermal‐hydraulic performance . The optimized geometric sizes agree well with those obtained by Massachusetts Institute of Technology ,which demonstrates the code relia‐bility and accuracy .关键词
