【摘要】 核电站反应堆发生泄漏的最主要原因是反应堆堆内构件发生振动。引起堆内构件振动的诸多因素都具有随机性和模糊性。此文将模糊可靠性理论引入核电站堆内构件振动系统,以现有核电站大量的设计运行参数和经验为基础,分析了影响核电站堆内构件振动可靠性的模糊因素,提出了防止振动发生的模糊可靠性准则和模糊综合评判模型;并从机械设计与制造、热工水力设计、核反应性控制等多方面提出了一系列防止振动发生的可靠性措施,这些将有利于建立和完善堆内构件振动的模糊可靠性模型。更多还原

【Abstract】 It is pointed out that the main reason making nuclear power plants reactors leak is the vibration of internals of reactors. The factors which lead the vibration all have randomness and obscureness. The obscure reliability theory is introduced to the vibration system of interals of nuclear power reactor. Based on a quantity of designing and moving data, the obscure factors effecting the vibration reliability of the internals of nuclear power plant reactor are analyzed and the anti-vibration reliability criteria and the evaluating model are given. And the anti-vibration reliability measures are advanced from different quarters of the machine design and building, the thermohydraulics design, the control of reactivity, etc. . They may benefit the theory and practice for building and perfecting the vibration obscure reliability model of the reactor internals.更多还原
