US ITER researchers at the University of Wisconsin and Oak Ridge National Laboratory are developing advanced processes to assess ITER's unique tokamak components and materials in the presence of the tremendous amount of neutron flux and energy released by fusion reactions. The process, called neutronics analysis, involves a palette of complex computational codes and libraries for predicting neutron impacts.
