Question

In this problem, consider a heterogenous slab slab of length a = 24 cm alternating regions of fuel and moderator of the following compositions and widths: fuel - Ea1.3 cm-1,

vEf = 1.47 cm-1, īo = 0,0.2 cm-1, E, = 1.0 cm-1, vDf = 0 cm¬1,0.7 cm-1, Es width = 2 cm; moderator - Eapīo = 0, width =1 cm. The boundary conditions on the slab are extrapolated endpoint conditions: \phi\left(-\frac{a}{2}\right)=\phi\left(\frac{a}{2}\right)=0 1. Use the code you wrote in Part III to solve this problem with a spatialmesh of 240 cells of length 0.1 cm.
