Abstract Scope |
In this work molecular dynamics (MD) simulations were conducted to explore the primary radiation effects on Body-Centered Cubic (BCC) Fe nanoparticle. A series of 6 cascades for each primary knock-on atom (PKA) energy (5 keV, 10 keV, 20 keV, 30 keV and 40 keV) was simulated to assure statistical precision. It has been observed that defects created by neutron irradiations stay as a single to several size clusters. In each of the cases, they produce one block of a big cluster with several small clusters. The block cluster of interstitials (Is) stays at the near surface of the nanoparticle, however, vacancies (Vs) stay inside the nanoparticle. The study has shown that the total number of vacancy defects is larger than the total number of interstitial defects. |
