Özet

Although the scope of ASME Code Section III Division 5 is material qualification, issues outside the scope such as corrosion, fission production, and radiation interaction are very important for the materials that form the basis of a nuclear power plant reactor system to maintain their structural composition and stability against environmental conditions over time. 316H and Alloy800H are among the materials recommended in the ASME report for the construction of high temperature reactors. At the point of today's need for energy, it is necessary to determine the interaction parameters with radiation as well as the qualitative properties of these materials. In this study, potential energy functions, stopping power, and range calculations were performed for different stoichiometric versions of 316H and Alloy800H targets for alpha particles and protons. The Hartree-Fock wavefunction was used for the potential energy function, dielectric theory and effective charge approximation for stopping power, and the Gaussian quadrature method for range calculations. These calculated radiation parameters were found to vary depending on the density of the material, the amount of elements contained, and the mean excitation energy.
