先进堆非能动余热排出系统冷热芯位差阈值研究

Advance PWR Passive Residual Heat Removal System Cool Hot Core Potential Difference Threshold Research

介绍了先进堆非能动余热排出系统冷热芯位差阈值的概念和分析,结果表明:影响系统冷热芯位差阈值的主要参数是系统压力、系统阻力和SG液位等系统状态参数以及空气入口温度、空气侧阻力系数和烟囱高度等系统边界条件。

This paper introduce the concept which is the threshold between hot resource and cold trap of passive residual heat removal system of Chinese advanced PWR. The analyses results proven: The major parameter was systemic pressure, system resistance, liquid level, air in-net temperature, air side resistance and chimney height that is impact the threshold between hot resource and clod trap.
