摘要
利用固体径迹探测器测量处于微型反应堆不同位置的燃料元件内单位体积的裂变率，得到了堆的裂变率分布和总裂变率，并与其它参数相结合，求得了反应堆功率。同时，测量了对应功率下反应堆内辐照座的热中子通量密度，得到单位功率的热中子通量密度，即额定中子通量密度下的运行功率。文章给出的测量方法，避免了金箔法测量反应堆功率所引入的近似假设。
The fission rates in different position in reactor fuel elements are measured by solid state nuclear track detector(SSNTD) and then the fission rate distribution and total fission rate in reactorare obtained. The reactor POwer can be gotten with combination with other parameters.Meanwhile, the thermal neutron flux density at certain point is measured and then the thermalneutron flux density per unite power is given. Finally, the operation power at specified neutronflux density can be determined.
