WebFick’s law in reactor theory states that: The current density vector J is proportional to the negative of the gradient of the neutron flux. The proportionality constant is called the diffusion coefficient and is denoted by the symbol D. The derivation of the diffusion equation depends on Fick’s law, which states that solute diffuses ...

WebLet's examine how Fick's Second Law was developed. First, we're going to look at a volume element, and that volume element is going to be described in terms of the width of the element times the cross sectional area. So we're looking at a region which is a uniform cross section. We're going to be examining the flux that comes into this system ...
