Abstract

The present work was planned to evaluate the reactor production of 47Sc from calcium and titanium targets at Egyptian Second Research Reactor (ETRR-2) based on 46Ca (n, γ) 47Ca \(\mathop{\longrightarrow}\limits^{\beta - }\) 47Sc and 47Ti (n, p) 47Sc nuclear ractions, respectively. A comparison between the two routs in terms of specific activity of 47Sc and co-produced radioimpurities was carried out. The MCNPX2.7.0 code was used to estimate the levels of all radionuclides produced throughout as well as after the irradiation of 46CaCO3, natTiO2 and 47TiO2 targets. The computational results were verified by experimental measurements, and a good aggrement was found between both. Additionally, our results showed that 47Sc production is greatly preferred from titanium route rather than calcium route.
