Industry requires well-validated computation methods and computer codes for its nuclear applications. The predictive power of such tools must be established and users must be confident of their results. Model refinement requires that increasingly sophisticated tools be used. Moreover, the computing power available today no longer justifies a number of geometrical simplifications.
This report describes the results of challenging international benchmarks in three-dimensional radiation transport that contribute to the evaluation and validation of state-of-the-art computation methods and computer codes. It will be of particular interest to reactor physicists and radiation shielding specialists.
