In this work, we expand the weighted delta-tracking routine to include a treatment for scattering. The weighted delta-tracking routine adds survival biasing to normal delta-tracking, improving overall problem figure of merit. In the original formulation of this method, only absorption events were considered. We have expanded the method to include scattering, enabling the assessment of three test cases: a pressurized water reactor pin cell, a fast reactor pin cell, and a homogeneous fuel element. We examine the results of these test cases and compare the final figure of merit of infinite flux and total cross-section while incrementally changing the amount of weighted delta-tracking used.
