An approximate analytic theory of a thick accretion disk is used to derive the thermodynamic conditions which prevail inside the disk as a function of the black hole mass, the viscosity parameter, and the accretion rate. From these thermodynamic conditions it is shown that, for a given mechanism for viscosity, the nuclear burning is substantially greater when the central black hole is less massive. A preliminary analysis of the main nuclear processes which can occur inside a thick disk is also performed. 49 references.
