基于DLL的GOTHIC8.0程序氢气复合器模拟方法研究

摘要

非能动氢气复合器已广泛应用于核电厂氢气威胁的缓解和消除.本文通过对GOTHIC 8.0程序进行二次开发,采用外部动态链接库(DLL)编译、调用的方式,精确模拟了非能动氢气复合器的实际消氢能力,进而将采用该方法计算得到的消氢结果分别与公式计算、MAAP5程序算例计算结果进行比较,结果符合度高,验证了该方法的合理性.本文提供的模拟方法不仅为安全壳氢气风险缓解分析提供了新方法,也为GOTHIC程序开发提供了新思路.%Passive hydrogen recombiner is widely used in mitigating and eliminating hydrogen threat in nuclear power plant.GOTHIC 8.0 code was secondary developed through DLL (dynamic link library) compiling and calling,and the eliminating capability of the passive hydrogen recombiner in a more accurate manner was simulated in this paper.The accuracy of this method was verified by comparing the results with correlation calculation and MAAP5 code case calculation,and both results matched well.This paper not only provides a new method for analyzing containment hydrogen risk mitigation,but also provides a new function for developing GOTHIC code.
