摘要
长寿命反应堆的设计要求主要是高燃耗深度和满功率自然循环能力,既要提高堆芯的转换比以获得最小的反应性随燃耗变动,又要充分考虑热工方面自然循环的要求,在一般基于铀钚燃料的长寿命反应堆设计中很难做到两全齐美。本文提出了一种基于乏燃料钚-钍燃料、铅铋合金冷却剂的长寿命堆设计方案,充分利用钍铀燃料在快中子条件下优越的核性能,完成了详细的概念设计并使用MCBurn程序分析其各项属性。
The design objectives of a long life reactor include the high fuel burnup and full power natural circulation,which increases the difficulty of reactor physical design: a higher conversion ratio to achieve zero reactivity swing with burnup and increase the P/D ratio to achieve natural circulation.It is a hard mission for the U-Pu fuel long life reactor design.This paper describes a spent Pu-Thorium fuel and lead-bismuth coolant based long life core design,taking the advantages of thorium fuel in fast neutron spectrum.The MCBurn code is chosen to perform the physical calculations..
