摘要
核反应堆的自然循环可提供非能动余热排出能力,有利于提高反应堆的固有安全性。本文以一体化压水堆概念设计方案为对象,利用RELAP5/MOD3.4程序对强迫循环转自然循环过渡过程的瞬态特性进行分析,探讨了反应堆功率、主泵阻力、主泵转动惯量等因素以及不同运行策略对转换过程瞬态特性的影响规律。
Natural circulation of nuclear reactor has heat dumpling capacity, which can improve the inherent safety of reactor. In this paper, the conceptional design of integrated pressurized water reactor was studied and RELAP5/MOD3.4 was used to analyze transient characteristic in the process from forced circulation to natural circulation. What＇s more, the influence of reactor power, resistance, moment of inertia of main pump, and various operation strategies on transient characteristic in this conversion process were also studied.
