摘要

针对核电厂运行瞬态分析的功能需求，中国核动力研究设计院研发了PANTO（Program for Analysis ofNormal Transient and Overpressure）软件。该软件基于成熟可靠的系统分析模型和特殊部件模型，采用模块化的软件设计理念，应用面向对象的C++语言和java语言，具有完全自主知识产权。PANTO软件通过了单元测试、集成测试和系统测试，基本消除了所有的代码缺陷。针对秦山二期核电厂阶跃负荷增大10%与额定功率下全部甩负荷瞬态试验进行了验证计算。结果表明，PANTO软件能够较好地模拟瞬态中关键参数的变化情况，计算精度满足工程应用要求，适用于压水堆核电厂运行瞬态分析。

Abstract

Background

The operational transient of a nuclear power plant mainly refers to transients or events that occur frequently or periodically during commissioning or power operation. The transient process involves the response of primary loop

secondary loop and the control system. Usually

particular software is used for transient analysis. Purpose:This study aims to develop the program for analysis of normal transient and overpressure (PANTO) software that fulfils the requirements of operational transient analysis.

Methods

Based on the mature and reliable system analysis model and special component model

object-oriented C++ language and java language were applied to design the modular software with completely independent intellectual property rights for PANTO. Through the unit testing

integration testing and system testing

all detected code defects were eliminated. Validation calculations were carried out for the 10% load step increase and complete load ejection at full power transient test which performed in the Qinshan Phase Ⅱ nuclear power plant.

Results

The results show that the PANTO can simulate the key parameters variation in the transients

and the calculation accuracy can meet the requirements of the engineering application.

Conclusion

The PANTO is applicable for operational transient analysis of PWR nuclear power plant.
