Vacancy Void Growth Rate as a Function of the Neutron Irradiation Parameters at the Initial Stage of Transient Swelling

详细

The growth of a radiation-induced void after its nucleus has reached a critical size is described in terms of a point defect migration model. The void growth rate (conventional dd/dt and dose-controlled dd/dD) as a function of irradiation temperature T and the generation rate of atomic displacements G is investigated at the initial stage of the transient swelling in an EK164 steel used as the fuel cladding in fast neutron reactors.
