Abstract: This report describes the TOTMOS code, which calculates the scalar neutron spectrum in a reactor cell as a function of the position by the collision probability method. One-dimensional cylindrical or spherical geometries can be treated. The neutron spectrum is used to compute cell-weighted cross sections, which can be used in gross reactor calculations. Furthermore, "equivalent" cross sections are calculated, which are employed to study the efficiency of absorber rods in a reactor on the basis of the diffusion theory.
