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.

“…Neutron and proton distributions of Li and Beisotopes were studied using the new Skyrme-force parameters by Baldik et al [22]. Tel et al [23] made a study of [8][9][10][11][12][13][14][15][16][17][18] Be isotopes using as a neutron multiplier in reactor design using HartreeFock approximation. The calculations of double-differential neutron emission cross sections for 9 Be target nucleus at 14.2 MeV neutron energy has been investigated by Ş ahan et al [24].…”

The knowledge of the cross-section is important especially for the fusion and fission reactor technology. In the absence of experimental data or in the difficulty of measuring data, theoretical predictions of nuclear crosssection data are needed to be improved using model calculations or semi-empirical formulas and to be compared with model and formulas to obtain sensitive approaches. In this work, for 7 Li and 9 Be target nuclei used as blanket materials in fusion reactors, (n,p), (n,a), (n,2n) and (a,n) reaction cross-section data have been evaluated by using some available empirical and semi-empirical cross-section formulas. The (n,p), (n,a), (n,2n) and (a,n) reaction crosssection formulas developed for medium and heavy mass nuclei by some scientist in literature are applied to 7 Li and 9 Be light nuclei and then results obtained from any systematics are compared with each other and the existing experimental data.

“…At present, beryllium is primarily obtained from the minerals beryl (Be 3 Al 2 (SiO 3 ) 6 ) and bertrandite (4BeOÁ2SiO 2 ÁH 2 O) through a chemical process. Beryllium (Be) has five known isotopes: 6 Be, 7 Be, 8 Be, 9 Be and 10 Be, but only one of these isotopes ( 9 Be) is stable with a natural abundance (100 %) and is a metal of low mass-density. The properties that make it ideal for specific nuclear applications include the lowest absorption cross section for thermal neutrons of all metals, the readiness to part with one of its own neutrons in (n,2n) reactions, and a high melting point.…”

“…The (n,2n) reactions can play a fundamental key role for multiplying neutrons. In many nuclear reactor designs, it is desirable not only to retain the neutrons within the reactor core, but also to reduce the energy of the neutrons so that they more effectively sustain the fission process [6][7][8].…”

“…Tel et al computed nuclear structure properties of the some nuclei including Beryllium ( 9 Be) by using the T3, SIII, SKM, and SLy4 parameters [16,17]. They also calculated nuclear charge, neutron and proton radii, skin thickness and binding energy of [8][9][10][11][12][13][14][15][16][17][18] Be isotopes by using the SI, SIII, SVI, T3, SKM, and SKM* Skyrme parameters [8]. In the present paper, the emission spectra for the 9 Be structural fusion material were investigated by using the Hybrid Monte Carlo simulation model [18] for pre-equilibrium emissions at the bombarding energy of 14.2 MeV.…”

In this study, we investigated neutron-emission spectra induced by (n,xn) nuclear reactions for the 9 Be structural fusion material at 14.2 MeV neutron energy. We calculated double-differential cross sections ( d 2 r dXde ) with ALICE-2011 codeor the angles of 30°, 60°, 90°, 120°, and 150°. Hybrid Monte Carlo simulation model have been used to calculate the double differential emission spectra for these different angles. The obtained results were compared with the measured data taken from EXFOR library. The results show an acceptable agreement.
