双探测器互相关噪声技术是六十年代新发展的反应堆动态参数测量方法。它的优点是:对堆芯不引入扰动,信噪比高,位置效应较小,方法简便可靠。研制了一种互相关测量专用装置,测量了高通量工程试验堆及其零功率堆和低浓铀水栅零功率堆的动态参数。 , Double detectors cross-correlation noise technology is the development of new reactor dynamics parameters measurement method in the 1960s. Its advantages are: the core does not introduce disturbances, high signal to noise ratio, the location effect is small, the method is simple and reliable. A special device for cross-correlation measurement was developed to measure the dynamic parameters of high-flux test reactor and its zero-power reactor and low-enriched uranium zero-power reactor. ,
