摘要
为验证涂硼正比计数管在高中子通量密度下的辐射性能参数,搭建出符合实际工程应用的测量通道。通过提升反应堆不同功率台阶的方法,分别对涂硼正比计数管探测器性能进行堆上试验验证。堆上试验结果表明:自主研制的涂硼正比计数管探测器满足设计要求,可应用于核电厂堆外核测量系统源量程测量通道。
In order to verify its radiation performance parameters at high neutron fluxes,the source range measurement channel of the off-stack nuclear measurement system uses boron-coated proportional counter tubes,which are configured to meet the actual engineering applications in conjunction with nuclear power field use.The on-stack test conditions and system configuration are given,and the on-stack tests are performed to verify the performance of the boron-coated orthogonal counter tube detectors by upgrading the reactor to different power steps.The on-stack test gives the boron-coated NPP screening threshold curve,high voltage ping characteristic curve,repeatability and linearity compliance,and the results are analyzed to confirm that the developed boron-coated NPP detector meets the design requirements and can be applied to the source range measurement channel of the off-stack nuclear measurement system of nuclear power plants.
