“…PFMs will operate under extreme condi tions of temperature, irradiation and thermal stresses because of their direct exposure to the fusion plasma. Furthermore, material choice plays a central role in the environmental safety of fusion power reactors in future commercial energy plants [5,6]. A suitable PFM should contain elements of reduced activation in such a way that production of radioactive by products and tritium inventories are minimized [7].…”

Abstract:The oxidation behavior of International Thermonuclear Experimental Reactor (ITER) reference tungsten grade has been evaluated in dry air in the temperature range 600 800 °C. At 600 °C, the scale remained protective while the integrity of W 18 O 49 layer was kept. Rapid increase in mass gain resulted from mas sive cracking at local areas in the W 18 O 49 layer. Then, a coarse non protective columnar WO 2.92 scale was developed which favoured rapid inward oxygen transport into the alloy. At 700 and 800 °C, growth stres ses in the scale were released through local cracking. At this stage, WO 2.92 became progressively trans formed into WO 3 when the oxygen partial pressure increased across the scale thickness.

The fusion energy is attractive as an energy source because the fusion will not produce CO 2 or SO 2 and so fusion will not contribute to environmental problems, such as particulate pollution and excessive CO 2 in the atmosphere. The fusion reaction does not produce radioactive nuclides and it is not self-sustaining, as is a fission reaction when a critical mass of fissionable material is assembled. Since the fusion reaction is easily and quickly quenched the primary sources of heat to drive such an accident are heat from radioactive decay and heat from chemical reactions. Both the magnitude and time dependence of the generation of heat from radioactive decay can be controlled by proper selection and design of materials.

“…Skyrme interaction V Skyrme can be written as the sum of two-and three-body parts [13]. The Skyrme forces with the three-body term replaced by a density-dependent two-body term, which are unified in a single form as an extended Skyrme force [14]:…”

Shell model and Hartree-Fock calculations have been adopted to study the elastic and inelastic electron scattering form factors for 25Mg nucleus. The wave functions for this nucleus have been utilized from the shell model using USDA two-body effective interaction for this nucleus with the sd shell model space. On the other hand, the SkXcsb Skyrme parameterization has been used within the Hartree-Fock method to get the single-particle potential which is used to calculate the single-particle matrix elements. The calculated form factors have been compared with available experimental data.
