The influence of accretion in the evolution of CO white dwarfs is calculated, up to the thermonuclear runaway, with a previous analysis of the H-He burning shell. For this later study, a two-zone model is developed, consisting of two thin shells in plane-parallel approximation. The influence in the inner core evolution is discussed.
