二次开发的RELAP5在倾斜条件下对PRS运行分析的适用性研究

He jishu
为验证经二次开发后的RELAP5程序在倾斜条件下的适用性，基于缩小比例的反应堆二次侧非能动余热排出系统（Passive Residual Heat Removal System，PRS）实验装置，开展了倾斜角度为-24°~+24°的工况下的余热排出实验。在此基础上，使用二次开发后的RELAP5程序对实验工况进行了模拟计算，利用实验数据验证其适用性，并进行了进一步对比分析。研究结果表明：二次开发后的RELAP5程序能有效预测倾斜条件下系统运行特性的变化 ...

RELAP5 assessment: LOFT large break L2-5

, 1984
RELAP5 is part of an effort to determine the ability of various systems codes to predict the detailed thermal/hydraulic response of LWRs during accident and off-normal conditions. The RELAP5 code is being assessed at SNLA against test data from various integral and separate effects test facilities.

Steam generator identification using piecewise affine model

Results in Nonlinear Analysis, 2019
The role of steam generators in power plants is to remove the thermal power produced in the first cycle and provide the turbine intake steam. Controlling the steam generator water level has an important role in preventing unwanted turbine trips and ...
