摘要

抑制涌动瞬态能够显著地减少稳压器波动管的热应力水平,对保持波动管在电站寿期的完整性和提高其可靠性有重要的意义,除设计改进外,有效的运行策略对抑制涌动瞬态具有非常大的作用。本文分析影响AP1000波动管涌动瞬态的运行工况和主要参数,建立连续的波动管涌出工况和减少系统温差最大值的总体策略,综述机组正常运行及启停工况下的有关操作。
        Restraining of surging transients can significantly reduce thermal stressing of pressurizer surge line,and it is necessary for keeping surge line's integrity and reliability. It's helpful to restrain surging transient establishing operational strategies effectively. This paper analyzes operating conditions and major parameters affecting Pressurizer surge transient,establishes general strategies of reducing temperature difference and maintaining continuous surge line outsurge,and summarizes specific operation during normal startup/shutdown.
