球形托卡马克聚变嬗变堆中子学设计

摘要

Based on studies of spherical tokamak fusion reactors,a concept of fusion-transmutation reactor is put forward.A set of plasma parameters suitable for the transmutation blanket is selected.Using the transport and burn-up calculation code BISON3.0 and its associated database,transmutation rate of MA nuclear waste,energy multiplication,and tritium breeder rate in the transmutation blanket are calculated.%基于对球形托卡马克ST聚变堆的研究，提出了ST聚变嬗变堆的设计概念。对堆芯参数作了初步选择，确定了一组适合于嬗变包层的堆芯参数供中子学计算和结构设计参考，给出了旨在以嬗变次锕系元素(MA)核废物为目标的一维中子学计算结果。
