International Conference on Nuclear Data for Science and Technology (ND) -- SEP 11-16, 2016 -- Bruges, BELGIUMSARPUN, Ismail Hakki/0000-0002-9788-699XWOS: 000426429500253In fusion reactors, neutron induced radioactivity strongly depends on the irradiated material. So, a proper selection of structural materials will have been limited the radioactive inventory in a fusion reactor. First-wall and blanket components have high radioactivity concentration due to being the most flux-exposed structures. The main objective of fusion structural material research is the development and selection of materials for reactor components with good thermo-mechanical and physical properties, coupled with low-activation characteristics. Double differential light charged particle emission cross section, which is a fundamental data to determine nuclear heating and material damages in structural fusion material research, for some elements target nuclei have been calculated by the TALYS 1.8 nuclear reaction code at 14-15 MeV neutron incident energy and compared with available experimental data in EXFOR library. Direct, compound and pre-equilibrium reaction contribution have been theoretically calculated and dominant contribution have been determined for each emission of proton, deuteron and alpha particle.Afyon Kocatepe University's Scientific Research Office (BAPK) [16.KARIYER.34]This work is supported by the Afyon Kocatepe University's Scientific Research Office (BAPK) Contract No. 16.KARIYER.34

Investigation of the effects of nuclear level density parameters on the cross sections for the U-234(gamma,f) reaction

International Workshop on Theoretical and Experimental Studies in Nuclear Applications and Technology (TESNAT) -- APR 23-26, 2015 -- Osmaniye Korkut Ata Univ, Osmaniye, TURKEYSARPUN, Ismail Hakki/0000-0002-9788-699XWOS: 000358306300006In this study, we have investigated the effects of nuclear level density parameters on the cross sections for the U-234(gamma,f) reaction up to 20 MeV. The cross sections on U-234(gamma,f) reaction were calculated for different level density models using the TALYS 1.6 code. First, it was determined the level density model that was the closest to the experimental data. Secondly, cross sections obtained for different level density parameters of this model were compared with experimental data from the EXFOR database. Thus it was determined the best level density parameter fit to experimental data.Turkish Atom Energy Author, Sci & Technol Res Council Turkey, Private Osmaniye Bilim Sch, Private Osmaniye Doga Sc

Theoretical investigation of cross sections and astrophysical S-factors for the Mo-92(alpha,n)Ru-95 and Mo-94(alpha,n)(97) Ru reactions

The cross sections of the Mo-92(alpha, n) Ru-95 and Mo-94(alpha, n) Ru-97 reactions have been calculated at 5-20 MeV energy ranges. In theoretical calculations, the TALYS1.6 and NON-SMOKER codes were used. Also the astrophysical S-factors were calculated. Results of our calculations were checked to the experimental data obtained from EXFOR database.Turkish Atom Energy Autho

Double Differential Proton and Alpha Emission Cross Sections for Structural Fusion Materials Mo-94,Mo-95,Mo-96

SARPUN, Ismail Hakki/0000-0002-9788-699XWOS: 000382404800001In this study, double differential alpha and proton emission cross sections, which is necessary in determination of heating and damages in structural fusion material research, of Mo-94,Mo-95,Mo-96 target nuclei have been theoretically calculated by the TALYS 1.8 code at 14.8 MeV neutron incident energy and also compared with available experimental data in EXFOR library. The compound nucleus formation process and pre-equilibrium contribution were found as dominant in the emission of proton and alpha particles, the direct reaction contribution also was seen as dominant in higher particle emission energies
