为测量秦山核电站燃料考验组件的物理性能,设计了专用实验组件。用直接测量芯棒γ活性的方法,成功地得到了组件功率与大堆功率的关系。用棒栅反应性曲线刻度了组件反应性及失水反应性。用活化箔法测得中子注量率以及芯棒间的功率分配。并采取措施,在满足组件考验热工条件的同时,实现了兼顾Mo-Tc的生产。
In order to measure the physical properties of Qinshan Nuclear Power Station fuel testing components, special experimental components are designed. By directly measuring the activity of the mandrel bar γ, the relationship between the power of the module and the power of the stack is successfully obtained. The rod reactivity curve was used to calibrate the reactivity and dehydration reactivity of the module. Neutron fluence rate and power distribution between mandrel bars were measured by the activated foil method. And take measures to meet the component thermal test conditions at the same time, to achieve the balance of Mo-Tc production.
