摘要:Z-Pinch产生高能脉冲中子驱动以压水堆乏燃料或天然铀为燃料的次临界包层,以能源输出为主要目标,是实现能源可持续发展的可行途径。本文通过理论计算,分析了次临界包层在连续中子脉冲作用下的材料温度和输出功率随时间的变化规律,结果表明,通过合理的设计可以使材料温度在可接受
的范图内波动,系统输出功率在时间轴上可以得到稳定。关键调:Z-Pinch;次临界包层;脉冲功率;热工分析

Abstract: The high energy neutrons generated by the Z-Pinch facility can be used to drive a subcritical blanket, which is filled with spent fuel from PWR or natural uranium, so as to multiply the fusion energy by several times. It's a feasible and sustainable way of producing energy, and can be used to meet the growing energy demand. In this paper, we investigated the variation of materials temperature and output power under sequential neutron pulses.We concluded that,by appropriate design, the materials temperature can be limited in an acceptable range, and a constant power can be exported.
