Modelling heat and mass transfer around a natural fission reactor at Oklo


The 3D modelling has been used in quantification of thermal influence of a buried nuclear fission reaction on surrounding rocks. The Francevillian uranium deposit at Oklo (Gabon) is unique because it hosted the only natural fission reactor known to have occurred.

In order to quantify the thermal influence and the effects of water circulation induced by the fission reactor at Oklo, several numerical 2D and 3D models are used to evaluate the temperature field (plan of the study)
