摘要

超临界水冷快堆集快堆和轻水堆两种特性。整个堆芯冷却剂流量仅为现BWR的1/8

中子能谱硬于普通PWR

故有一定的核燃料增殖能力。本文建立不同Flower型超临界水冷快堆堆芯物理模型

研究堆芯分区布置、冷却剂密度分层、seed及blanket组件P/D值设计、MOX燃料设计、燃料富集度分区分层布置、blanket内部通道采用贫铀冷却等方案

分析堆芯的空泡反应性、功率分布及增殖比。通过比较

得到了超临界水冷快堆的优化设计方案。

Abstract

Supercritical Water-cooled Fast Reactor(SCWFR) presents features of combining fast and light water reactor characteristics in one design.The coolant mass flow rate is just as 1/8 as in the BWR

and the neutron energy is harder than in PWR

so it would has the breeding ability.In this paper

using different models of improved Flower-SCWFR core

the void reactivity effect

power distribution

and breeding ratio are analyzed by core zoning scheme

axial coolant densities zoning

seed and blanket assembly with suitable P/D value

MOX fuel with different design and enrichment zoning

and solid uranium matrix cooled by internal clad channels in blanket assembly.Finally

an optimized modal of the improved SCWFR cores-"Flower type" is obtained.
