Summary on Grant Application Form |
|
The research will investigate the evolution of radiation damage that occurs in ferritic steel in power reactors between the short-term (~1 ps) creation of the primary defect production in displacement cascades and the long-term (~1 s) changes in microstructure which affect material performance. This will be achieved by developing a stochastic annealing code to simulate defect behaviour and undertaking computer simulations to determine the stability and migration characteristics of defects in alpha-iron. The overall aim will be to use stochastic simulation to investigate the time-, temperature- and energy-spectrum-dependence of the evolution of vacancies and interstitials that survive intracascade recombination. The effect of different distributions of sources and sinks, and the interaction of intrinsic point defects and solute atoms, will also be studied. Data on primary cascade damage in iron under a wide range of conditions are required and are available from work already undertaken at Liverpool. We are to the fore in this field of research, and linking the timescales in the way proposed is seen as essential for the next phase of development of damage modelling. The work is aimed at providing fundamental understanding of damage evolution and will be cofunded by Magnox Electric plc under the ERCOS scheme.
