The transport equation is considered in toroidal geometry using an expansion of Ψ(r, Ω) in unnormalized spherical harmonics, i.e., with being associated Legendre polynomials. The variable r is the position vector and Ω the direction with axial and azimuthal angles θ and , respectively. Equations for ψlm(r) and γlm(r) are obtained and a method of solution that has worked in other geometries is outlined.
