铀氢锆堆中央孔道中子注量测量及校正

Measurements and Corrections Methods for Neutron Flux in UHZr Reactor Center Porthole

反应堆中央孔道中子注量值是反应堆的重要指标,也是反应堆应用的重要参数。本文简要介绍了用锆箔法测定中央孔道中子注量的方法,着重讨论和分析了影响其测量准确度的几种主要因素,并给出了铀氢锆堆中央孔道中子注量的测量结果。

The neutron flux of reactor center port-hole is one of the important parameters for applications. The paper briefly introduces the Zr dual-isotopes method for reactor neutron flux measurements, discusses and analyzes some important factors affecting the precision of the measurement results. The measurement result of neutron flux for the center porthole of the uranium zirconium hydride (UHZr) reactor is presented.
