加速器驱动次临界核能系统高功率质子直线加速器概念研究(英文)

加速器驱动次临界核能系统(ADS)是下一代能源的首选方向。它能有效地利用铀和钍资源,嬗变长寿命高放射性废物和提高核安全水平。ADS加速器应能提供几十兆瓦质子束。超导直线加速器(SCL)效率高,束流损失少,是ADS加速器的最佳选择。作者介绍的ADD加速器由5 MV射频四极加速器,100 MV独立调相超导腔加速器和1 GV椭圆超导腔加速器组成。确定了加速结构和主要参数,考虑了研究和发展计划。

Conceptual Study of High Power Proton Linac for Accelerator Driven Subcritical Nuclear Power System*

As a prior option of the next generation of energy source, the accelerator driven subcritical nuclear power system (ADS) can use efficiently the uranium and thorium resource, transmute the high-level long-lived radioactive wastes and raise nuclear safety. The ADS accelerator should provide the proton beam with tens megawatts. The superconducting linac is a good selection of ADS accelerator because of its high efficiency and low beam loss rate. The ADS accelerator presented by the authors consists of a 5 MeV radio-frequency quadrupole, a 100 MeV independently phased superconducting cavity linac and a 1 GeV elliptical superconducting cavity linac. The accelerating structures and main parameters are determined and the research and development plan is considered.
