Reactor vessel internals radiation analyses

A computational method for analyzing a radiation field in a light water nuclear reactor, comprising:

• performing a neutron and gamma transport calculation of a reactor geometry model of said light water nuclear reactor for at least one fuel cycle;
• analyzing flux data calculated by the neutron and gamma transport calculation for materials and/or components within said light water nuclear reactor;
• and
• calculating radiation exposure for components within said light water nuclear reactor which have more than one different location during or between the at least one fuel cycle.
