" copper embrittlement of older reactor steels" . . . . . "Copper is introduced into the steels of reactor vessels by diffusion from welding material, and forms small precipitates which contribute to embrittlement of the irradiated ferritic steels in nuclear power stations. The proposal of the project is motivated by efforts to understand micromechanism of the embrittlement. Molecular dynamic simulations will be utilized to study: micromechanics of defect growth in 2D and 3D, equilibrium atomic structure of nano-scale precipitates embedded in alfa-iron, the conditions leading to nucleation and microcrack growth at the interface host - precipitate, further radiation damage and dislocation pinning in alfa-iron containing the Cu-impurities."@en . .
