Abstract
A fully dynamic rate theory for modeling the behavior of point defects in metals during time dependent irradiations has been formulated. The state variable approach has been used to determine the microstructure and defect concentrations as a function of time. The resulting system of stiff non-linear first order ordinary differential equations is solved by the GEAR Program and incorporated into a FORTRAN Computer Code, TRANSWELL. This code has been developed to solve the previous system of equations under a variety of irradiation conditions. It is shown that the point defect and microstructural behavior during the transient phase of an irradiation is quite different than that found after steady state operation.Keywords
