Critical Experiments—Benchmarks (Pu-U Systems)

Fourteen different critical systems of plutonium-uranium homogeneous mixtures are arranged in a format amenable for use in validating calculational techniques and checking nuclear data. Each experimental system is completely defined under a single benchmark number. For the data that permit it, multiple critical dimensions are given for each fuel composition and geometry. Wherever possible, experimentally determined correction factors are provided for reducing the complexity of the critical assemblies.
