摘要
描述了200MW核供热反应堆(NHR-200)重力注硼系统启动时发生的各种热工水力学现象。推导了描述该系统动态特性的微分方程组。在此基础上提出了在缩小比例的实验系统上进行模拟实验研究时应遵循的模拟准则,即几何准则,联通准则,流动准则,汽化准则及冷凝准则。分析了各准则在注硼系统动态过程中的作用及相对重要性。给出了在几种简化条件下描述该重力注硼系统的微分方程组及模拟准则。此研究对建立重力注硼模拟研究系统,对分析该系统的热工、流动及工作特性,对NHR-200的安全都有重要意义。
Different kinds of thermohydraulic phenomena during startup of gravity boron injection system (GBIS) of the 200MW nuclear heating reactor (NHR200) were described. A set of differential equations governing the dynamic behavior of the GBIS is derived. Based on the derivation the simulation criteria, namely geometry, connection, flow, evaporation and condensation criteria being followed by experimental simulation study are proposed. The function and relative importance of these criteria in the dynamic process of the GBIS are also analyzed. At last, the set of differential equations and the criteria are simplified under some simplification of the thermohydraulic process of the GBIS.
