Coconut Creek (Florida), ISSN 0749-0208.With the wide application of nuclear energy in marine nuclear power plant, the nuclear safety analysis of marine nuclear power reactor has become inevitable, and has been gradually concerned. Radiation safety criterion is an important index of safety analysis of nuclear power plant. Because of the characteristics of the reactor, its radiation protection management has higher and more strict requirements, which makes strengthening radiation protection become an important task of the reactor. The radiation solution method of marine nuclear power plant based on 3D neutron transport equation is proposed. Firstly, the program mathematical model of dose field analysis of marine nuclear power reactor cabin is constructed to obtain the radiation dose field of marine nuclear power reactor cabin. Then, based on the obtained nuclear radiation measurement field information, the radiation solution of the marine nuclear power plant is realized by the discrete solution method based on the 3D neutron transport equation. It is verified that the method has high accuracy and credibility for radiation calculation of an offshore nuclear power plant.
