Consider a one-dimensional slab of thickness R, containing a material with macroscopic absorption cross section a and diffusion coefficient D, and internal neutron source density s(x)=2s0xR. The left side of the slab )=(0 has a vacuum (escape) boundary condition where we may assume that the scalar flux is zero, (0)=0. The right side of the slab )=(R has a zero net current (reflecting) boundary condition, J(R)=0.
Verify that (x)=2L2s0xDR is a particular solution to the one-speed, one-dimensional, steadystate neutron diffusion equation for this slab.
Following the examples shown in class, solve the one-speed, one-dimensional, steady-state neutron diffusion equation to determine the scalar flux as a function of position, (x),within the slab.
Using R=180cm,D=10cm,a=0.0015cm-1, and s0=1 neutron ?cms, plot the scalar neutron flux (x)(obtained in problem 2) from x=0 to R
