Nuclear instrumentation system power measuring range coefficient scale experiment execution opportunity optimization method

The invention belongs to the technical field of nuclear power plant nuclear power monitoring physical experiments, and particularly relates to a nuclear instrumentation system power measuring range coefficient scale experiment execution opportunity optimization method. Through theoretical analysis and practical experiment optimization verification, when xenon is not balanced, the scale experiment is performed; the experiment result meets the acceptance criteria. The debugging main line time occupation by scale experiments can be effectively reduced; the probability and the risk of xenon oscillation caused by reactor core state regulation under the condition of steady state are reduced; the flexibility of planning and arranging experiments can be improved; the calibration and regulation of the nuclear instrumentation system power measuring range coefficient can be completed in advance; the safe operation of the nuclear power plant is ensured. 本发明属于核电厂核功率监督物理试验技术领域，具体涉及种核仪表系统功率量程系数刻度试验执行时机优化的方法。本发明通过理论分析和实际试验优化
