The 3D radiation transport benchmark problems proposed by Kobayashi were ca
lculated by the three-dimensional Sn transport code TORT3.2 with the first
collision source code FNSUNCL3 newly coded for TORT. The calculated total n
eutron fluxes had no ray effect and showed good agreement with the analytic
al and GMVP solutions. It was demonstrated that FNSUNCL3 is quite effective
