One of the key questions in cosmic-ray astrophysics is the nature of physical processes relevant to propagation in the Galaxy. While the fundamentals of cosmic-ray propagation are thought to be understood, no single quantitative model can yet account for the spectra of all secondary components. A critical examination of the production and propagation of all secondary particles is therefore imperative. In this paper we use the simplified propagation models of Standard Leaky Box, Galactic wind at constant speed, and sto chastic reacceleration to calculate the expected flux of cosmic-ray deuterons in the interstellar medium. By enumerating and examining the uncertainties in the calculations we obtain estimates for the prediction of the three models.
