The solution of two-dimensional neutron diffusion equation with delayed neutrons
Informatica, 2001 Summary: The distribution of the neutron population in a nuclear reactor is described by using transport equations. One of the possible approximations of the neutron transport equation is given by the neutron diffusion equation. The paper presents a numerical solution method for the one group neutron diffusion equation with one group of delayed ...

On the Modelling of Thermal Aging through Neutron Irradiation and Annealing
Advances in Materials Science and Engineering, 2018 A new method predicting long-term thermal embrittlement of steel caused by P segregation is verified. The method is based on the results of impact strength or fracture toughness tests using specimens after relatively short-term neutron irradiation ...
