Recent extensions of the Transmission and Escape Probability methodology and its implementation in the
2-D neutral transport code GTNEUT are presented. These extensions address the issues of anisotropy of
the neutral distribution function at the interfaces and the non-uniformity of the first collision source in
short mean free path regions. Comparisons with Monte Carlo for a number of model problems are
discussed.
