摘要

超温/超功率ΔT保护是压水堆电厂的重要保护功能，初步安全分析报告(Preliminary Safety Analysis Report

PSAR)技术规格书一章对其响应时间的测试有强制要求。基于IEEE388对保护系统响应时间测试的要求，根据超温/超功率ΔT保护的算法及标准设计方案，提出了AP1000超温/超功率ΔT保护响应时间的推荐测试参数，并重点分析了保护系统动态补偿对于响应时间测试的影响。分析发现动态补偿对于测量响应时间有一定的影响，为得到可信的、保守的测量结果，在进行超温/超功率ΔT停堆保护响应时间测试时，应该保留动态补偿环节。

Abstract

Background: The over temperature/over power ΔT (OT/OP ΔT) is a key protection to Pressurized Water Reactor (PWR) and the response time testing of the protection is required in technical specifications of Preliminary Safety Analysis Report (PSAR). Purpose: To have credible response time testing of the protection

including the effects of dynamic compensation unit

analysis was conducted on the requirements of the rules and the application of the design. Methods: Firstly

the application of the protection algorithm is analyzed. Then the requirements of IEEE388 and the dynamic response of the typical dynamic compensation units upon step and impulse stimulations are studied. Results: Base on the analysis

corresponding to the nominal thermohydraulics and the instrumentation and control design

a recommend testing parameter configuration set for AP1000 OT/OP ΔT protection response time testing is developed. The non-negligible effect of dynamic compensation units is concluded as well. Conclusion: As a result

the requirement of having the dynamic compensations on line for the response time testing is strongly proposed. Abstract
