| 摘 要： | 反应堆功率的测量,在堆功率高时一般用热工方法,功率低时,可用各种堆物理方法,如中子源引进法、中子统计法和全堆总裂变率法。 中子源引进法误差较大,中子统计法需知探测器在堆内的效率和堆的β_(aff)值,此二者都较难测量。全堆总裂变率法是由测量堆的总裂变率来求得堆功率,它可避免前面两种方法的缺点,但需依赖裂变率相对分布的

| Abstract: | The power calibration of the zero-power reactor of uranium water lattice can be derived from the total fission rate of the whole reactor. The total fission rate depends on the thermal neutron flux at certain point of the reactpr core, fuel cadmium ratio. 235U fission cross section, 235U nuclear number in the whole reactor and the relative distribution of the fission rate in the reactor core. In this paper the thermal neutron flux in certain point of the reactor core, the total fission rate of the whole reactor and the reactor power have been determined. |
