摘要

本文研究了含Hf金属发射体的康普顿发射探测器。利用MCNPX软件模拟了WWER-1000堆芯4次燃料循环过程中发射极材料的行为。该研究考虑沿堆芯高度在目前使用的标准Rh探测器位置安装7个探测器。通过对7个spd的模拟，得到了以下几组数据：详细的核素组成；主要核素的（n, γ）反应速率；比中子损耗；N -和γ-通量分布；高频发射极的发射电流。

Modelling of the Compton neutron detector Hf emitter burn-up in the core of WWER-1000

The Compton emission detectors with a Hf metal emitters were examined in this study. MCNPX software was used to simulate the behavior of emitter material during 4 fuel cycles in the core of the WWER-1000 reactor. The study considered 7 detectors located along the height of the core at the positions of the standard Rh detectors currently in use. Through the simulation for 7 SPDs, it was obtained the following sets of data: detailed nuclide composition; rates of (n, γ)-reaction for main nuclides; specific neutron losses; n- and γ-fluxes distribution; the emissive current from the Hf emitter.
