Production of the ANITA-NC system able to treat material activation due to neutral or charged particles

ANITA-NC (Analysis of Neutron Induced Transmutation and Activation – Neutral and Charged) is an inventory system developed in ENEA-Bologna, capable of modelling the material activation induced by several neutral and charged projectiles (neutron, proton, alpha, deuteron and gamma). It is suitable to be applied to the study of the irradiation effects on materials in facilities like the International Fusion Materials Irradiation Facility (IFMIF) and, more recently, the DEMO Oriented Neutron Source (DONES), in which a considerable amount of neutrons with energies above 20 MeV is produced. In fact, in these facilities the deuterons will themselves cause activation, particularly in the accelerator structure and in the lithium target. ANITA-NC includes and extends the capabilities of the ANITA-IEAF code, able to assess the activation of materials exposed to neutrons with energies up to 55 MeV. ANITA-IEAF was released by ENEA to OECD-NEADB where is in free distribution (NEA-1638). In this report the main characteristics of ANITA-NC are given. An example of calculation for both deuteron and proton activation performed by ANITA-NC are also shown. The results are compared with the FISPACT-II predictions.
