Description
This paper examines the applicability of the Target Motion Sampling (TMS) temperature treatment method together with track-length estimators. Several track-length estimator based quantities are calculated in four test cases using a preliminary implementation of the method in OpenMC. The results are compared to an NJOY-based reference. The study reveals a statistically significant bias in the estimator results, but the errors were found to only affect limited energy regions, and their magnitude is relatively small as long as energy-integrated estimators are considered.
