Method for correcting measurement value of zero-power physical test isothermal temperature coefficient

The invention belongs to the technical field of nuclear reactor physics, and particularly relates to a method for correcting a control rod position-critical boron concentration of a measurement value of a zero-power physical test isothermal temperature coefficient. By adopting the method, the correction error in the measurement of the isothermal temperature coefficient is effectively reduced. A three-dimensional calculation model adopted in the method is closer to an operation state of a reactor core, and the influence of a rod position-boron concentration is considered while various reactor core state parameters are calculated, so that the correction error in the measurement of the isothermal temperature coefficient is greatly reduced. 本发明属于核反应堆物理技术领域，具体涉及种零功率物理试验等温温度系数测量值控制棒棒位-临界硼浓度修正方法，利用该方法可以有效地减小等温温度系数测量中的修正误差。本发明的方法采用三维计算模型更加接近堆芯运行状态，计算出各堆芯状态参数同时考虑了棒位-硼浓度的影响，大大减小等温温度系数测量中的修正误差。
