| 摘 要： | 在利用热工水力台架进行反应堆热工水力研究时，一般采用电加热代替核释热。由于反应堆本身存在温度效应、空泡效应等内部反馈，因此用电加热代替核释热时，还应以模拟这种内部反馈。本文分析了各种内部反馈的不同影响，提出了模拟的重点，并在此基础上提出了一个模拟内部反部反馈的方法。

| Abstract: | In the experimental research of reactor thermohydraulic behavior on test facility,anelectric heater is always used instead of a nuclear reactor There are many inherent reactivity feedback in a real reactor,such as temperature coefficient feedback and void coefficient feedback,so when an electric heater is used as a nuclear fuel in a test facility,it is required to simulate the reactivity feedback In this report,an analysis ofeffect of reactivity feedback is made and a method of simulating reactivity feedback is proposed |
