Uncertain Neutron Diffusion

Generally, every system possesses uncertainties caused by measurement errors, vague data and boundary conditions. Accordingly, the involved coefficients, parameters and constants become uncertain. Neutron diffusion is the backbone of a nuclear reactor. The scattering of a neutron occurs when it undergoes diffusion, which involves uncertainty due to the reactor parameters, measurement errors and boundary conditions. These uncertainties play an important role in the problems related to reactors, which should be understood well to help in a better design. In this chapter, we discuss the factors which may be considered as uncertain in a reactor system and then incorporate the corresponding idea of modelling.
