摘要
文章介绍加速器驱动次临界系统(ADS)中次临界实验装置———启明星1#的设计目的、要求、结构和可开展的工作。启明星1#是由快中子能谱区和热中子能谱区耦合组成的堆芯和由高压倍加器氘-氚反应中子源来驱动的次临界系统。快中子能谱区处在堆芯内部,该区提供快中子谱,还可放大外中子源,以驱动热区;热中子能谱区处在堆芯外部,主要用来能量放大,以维持装置的链式裂变反应。
Tthe design purpose, requirement and construction of the sub-critical assem bly-Venus 1# for accelerator driven sub-critical system（ADS） are described. It is a coupling core of the fast neutron spectrum zone and thermal neutron spectrum zone driven by DT reaction neutron source generated by pulsed neutron generator. The fast neutron spectrum zone is in the inner layer of core and the thermal neutron spectrum zone is in the outer layer of core. The fast neutron zone can give fast neutron spectrum and also is an amplifier for an external neutron source, and the thermal neutron zone is a fission zone and gives energy amplification.
