摘　　要：研制成ＦＲＳ－２型压水堆锆－４包壳电加热模拟燃料棒，提供一种先进的实验方法和瞬态测量技术，目的在于研究锆－４包壳在大破口ＬＯＣＡ条件下的鼓胀爆破行为，给出秦山核电厂安全分析所需的爆破数据。报道了模拟燃料棒的结构、性能、包壳鼓胀爆破实验方法和破口检验内容。Type FRS 2 PWR electrically heated fuel simulator with Zircaloy 4 cladding has been made, and the advanced experimental method and transient measuring technique are set up for studying Zircaloy 4 cladding ballooning and burst behavior under LB LOCA conditions to provide the desired burst data for safety analyses of Qinshan Nuclear Power Plant. This paper reports the structure and performances of the fuel rod simulator, the experimental method of Zircaloy 4 cladding ballooning and burst, and the posttest examinations at the rupture region.
