【摘要】 简要介绍了跳源法在ADS中子学研究中测量次临界度的原理、外源驱动的次临界中子学的实验装置、堆芯布置及中子源驱动系统。主要研究了252Cf中子源在堆芯不同轴向位置、模拟质子束管和散裂中子靶件处不同缓冲区材料对keff的影响。实验结果与其它实验方法的结果进行了比较,符合较好。更多还原

【Abstract】 The paper is concerned in the sourcejerk method u se d to measure the subcriticality, and the subcritical experiment facility, wh ich is used for the study on the neutronics of ADS, driven by external neutron s ource 252Cf. The effects of the location of neutron source and materia l buffer where is at the location of the pipe of proton beam and target of fissi onproduct dispersion on the subcriticality of reactor are studied by source jerk method.更多还原
