  The production of 26Al by explosions of classical novae has been computed by
means of a hydrodynamic code that follows both the accretion and the explosion
stages. A special emphasis has been put on the analysis of the influence of the
initial abundances of the accreted envelope, as well as on the nuclear reaction
rates involved. With the most recent values of chemical composition and
reaction rates available, 26Al production is lowered with respect to previous
computations. According to our results, the final contribution of novae to the
galactic 26Al is at most 0.4 M_sun, which is a small part of the estimated 26Al
in the Galaxy derived from COMPTEL observations of the 1809 keV emission.
