Sequare box reactor
Iam trying to work out question related to sequare box, my question is what the flux general equation for the sequare box?
I work it out and found it is
where a is side lenght, am i right

This assumes zero flux boundary condition at the edges (flux(-a/2) = flux(a/2) = 0), and max flux at flux(x,y,z) = flux(0,0,0) = A and even symmetry.
Flux is then described by 3 independent functions X, Y, Z which are described by X'' + (pi/a)2X = 0 and X(0) = Y(0) = Z(0) = A1/3

do you agree with me when we use neutron diffusion equation, that the general solution will be
and what about if we have no source and steady state? How the general equation going to be, should we take it as
