Abstract

Abstract

The two-dimensional Sn transport calculation code DORT and ENDF/BVI library are used to calculate the neutron flux distribution in PWR reactor pressure vessel,and the special activity source terms calculation code is developed and used to calculate the reactor coolant ¹⁶N and ¹⁷N activity source terms.It is used for the validation of the effect of core radial and axial power distributions.Results of sensitivity analysis indicate that it has little effect on the ¹⁶N and ¹⁷N activity source terms calculation results for low or high leakage core load mode of PWR NPP.
