采用测量结果拟合预测分布的方法自主研发了通量图处理软件MAPLE ，用于重构三维堆芯功率分布，以实现监测堆芯关键参数。采用权重系数法（WCM ）、多项式展开法（PEM ）和薄板样条函数（T PS ）法拟合二维平面上探测器信号的测量值与预测值的相对偏差，以推衍非探测器位置偏差。测试显示，T PS法能更好地还原信号偏差分布。采用岭澳核电站首循环的测量数据及堆芯计算程序SMART的输出结果作为MAPLE的验证输入计算功率分布，结果显示，MAPLE的计算结果令人满意。

The self-reliant flux map processing code MAPLE was developed by China General Nuclear Power Corporation (CGN ) . Weight coefficient method (WCM ) , polynomial expand method (PEM ) and thin plane spline (TPS) method were applied to fit the deviation between measured and predicted detector signal results for two-dimensional radial plane , to interpolate or extrapolate the non-instrumented location deviation .Comparison of results in the test cases show s that the T PS method can better capture the information of curved fitting lines than the other methods .The measured flux map data of the Lingao Nuclear Power Plant were processed using MAPLE as validation test cases ,combined with SMART code .Validation results show that the calculation results of MAPLE are reasonable and satisfied .
