研究堆周期保护装置堆上考验试验

Test on the Reactor with the Period Protection Device for Research Reactor

周期保护装置是研究堆必备的设备之一,属于核安全一级设备。新研制的周期保护装置在安装到反应堆之前,必须在零功率堆或其它反应堆上进行堆上考验试验,以检验其周期保护和周期测量功能及测量精度。叙述了新研制的三套周期保护装置在堆上考验的试验设施、试验堆芯、试验内容和方法以及试验结果。试验结果表明:三套周期保护装置均满足技术指标的要求,满足反应堆运行的周期测量和周期保护的要求。

Period Protection Device is necessary for research reactor,is of nuclear safety class Ⅰ.Test must be performed on the zero power reactor or other reactor before the Devices are installed in the reactor,in order to check its function of period protection and measurement,and the accuracy of measurement.The paper describes the test facility,test core,test items,test methods and test results.The test results show that all of the three Devices achieve the technical specification,and satisfy the requirements of period measurement and period protection during the operation of the reactor.
