摘　　要：文中就加速器驱动的反应堆系统靶的几何设计、泄漏中子产额、泄漏中子能谱及靶中能量沉积问题进行了研究 .提出了钨饼与水层组成的组合靶概念 ,在中子产额影响较小的情况下 ,较好地解决了固态靶散热问题 .The geometry of the solid target for the accelerator-driven system was optimized. The yield and spectrum of leaked neutrons, and the energy deposition in the target were studied. A target assembly consisting of tungsten diskes and water layers was proposed in the present work. The problem of large energy deposition in soild target was solved without decreasing the leakage neutron production.
