原型微堆辐照座物理特性参数模拟测定

SOME CHARACTERISTIAL PARAMETERS EXPERIMENTAL RESEARCH FOR IRRADIATION SITES OF MINISTURE NEUTRON SOURCE REACTOR

文章给出了原型微堆辐照座内的某些物理特性参数：相对中子通量密度分布、绝对中子通量密度，能谱参数（镉比、超热指标和中子温度），某些样品在辐照座内对反应性的影响以及各辐照座之间的相互关系。实验研究在原型微堆的零功率实验装置上完成。

Some characteristical parameters for irradiation sites of Miniature Neutron Source Reactor(MNSR)such as the neutron flux densities(absolute and relative),the energy spectrum parame-ters(R_(cd) subthermal index and neutron temperature),the effects of some samples on the reactor and the comparison among irradiation sites are given. Experiments are performed on the zero power experiment device of the Miniature Neutron Source Reactor.
