Classical novae are dramatic events that inject significant amounts of nuclear processed material into the interstellar medium. Nucleosynthesis accompanying nova outbursts suggests that classical novae are likely sites for the synthesis of the Galactic C-13, N-15 and O-17. Also some radioactive species, of particular interest for the gamma-ray emission from novae, such as Be-7,F-18, Na-22 or Al-26 are expected to be present in the ejecta. In view of recent improvements on nuclear reaction rates, we report on new hydrodynamical calculations of nova outbursts, in which larger amounts of Na-22 as well as much lower amounts of F-18 are obtained. Nuclear uncertainties associated with key reactions of the CNO and NeNa-MgAl "cycles" and their impact on nova nucleosynthesis are also discussed. [References: 11]
