Özet

Flibe (Li2BeF4) and Flinabe (LiFNaFBeF2) are molten salt which are used as a first wall and blanket in advanced power extraction. Since they have low vapor pressure at high temperature and don't pollute plasma. Moreover, they are used as a coolant material due to their high thermal cycling capacity. There are lots of benefits of using liquid wall such as reducing cost, increasing the reactor power and extending the life time of first steel wall. Being in Flinabe (LiFNaFBeF2) molten salt, (23) Na is also considered as a coolant material in fast reactors. Therefore, the reaction including neutron and (23) Na is getting important. In this study, the cross section calculations of neutron induced reactions for (23) Na were performed. Using pre-equilibrium and equilibrium models, excitation functions of (23) Na(n,p)(23) Ne, (23) Na(n,d)(22) Ne, (23) Na(n,alpha)(20) F, (23) Na(n,2n)(22) Na reactions and (23) Na(n,x alpha), (23) Na(n,xn) emission spectrums were calculated. We calculated alpha emission spectrum obtained when (23) Na nuclei projectiled with 14.1 MeV neutrons and also neutron emission spectrum emitted when (23) Na nuclei was bombardment with 14.6 MeV neutrons.
