Numerical Solution of two group uncertain neutron diffusion equation for multi region reactor

Every system involves uncertainty which come into play through various parameters, depending on initial and boundary conditions. Handling such uncertainty is a difficult task and the non-availability of experimental data results an idea of non-probabilistic method to solve imprecisely defined systems. In this regards fuzzy finite element is a tool to tackle uncertain or imprecisely defined system. Here a standard two group neutron diffusion equation is considered and a two group multi regional reactor problem is solved under the uncertain conditions. The results are depicted and compared with the special cases.
