Abstract

Abstract

Neutron spectrum adjustment is the effective method to estimate the neutron fluence in the nuclear power plant reactor pressure vessel（RPV）.The aim of this work is to develop the neutron spectrum adjustment code 2NP based on the generalized least squares method（GLSQM）,which will be used in neutron fluence estimation of RPV.The accuracy of the code 2NP have been proven by calculating the benchmark ANO issued by IAEA.
