Overview of recent progress in IFMIF neutronics

An overview is presented of the progress achieved in the development of computational tools, data and models dedicated to IFMIF neutronics and activation analyses. This includes the Li(d,xn) neutron source term modelling with the McDeLicious Monte Carlo code using tabulated d + 6,7Li cross-section data and the ALARA inventory code with IEAF-2001 data for activation and transmutation calculations. A special group activation data library based on the use of pseudo fission product yields was generated for use with standard activation codes. For IFMIF shielding calculations, a mapping approach was developed to couple full 3D McDeLicious calculations with the discrete ordinates (S N) procedure for deep penetration calculations using the TORT code. The recent achievements are reviewed and results are presented of specific nuclear and activation analyses conducted for the test cell and its components using a detailed 3D test cell model developed for Monte Carlo calculations with the McDeLicious code
