Comparison of neutron energy spectrum unfolding methods and evaluation of rationality criteria
文献摘要：
The neutron energy spectrum was measured using a Bonner sphere spectrometer at six locations inside the containment ves-sel of a nuclear reactor at the Qinshan nuclear power plant.The structures of the neutron spectra obtained by the maximum entropy,iteration,and genetic algorithm methods were consistent with one another and could be interpreted as the spectral superposition of different energy regions.The characteristic parameters of the neutron spectrum,including the fluence rate,average energy,and neutron ambient dose equivalent rate H*(10),were in good agreement among the three methods.In addition,an LB 6411 neutron ambient dose equivalent meter was employed to obtain the H*(10)directly for comparison.These findings indicate that neutron spectrum unfolding methods can be used to overcome the problems associated with the response functions of dosimeters to provide more accurate H*(10)values.In this study,the following three evaluation criteria were systematically addressed to ensure the accuracy of the unfolded spectra:count rates of the inverse solutions,neutron spectrum structures,and comparison of key parameters.
