We present the uncollided-flux treatment implemented in the Rattlesnake code system of the Idaho National Laboratory (INL). The ray-tracing method employed is capable of handling various types of finite-element meshes. Uncollided-flux techniques are necessary to capture streaming in low-density regions, such as the ones found in the TREAT test reactor at INL. Numerical results are presented.
