  The observable consequences of a nova outburst depend sensitively on the
details of the thermonuclear runaway which initiates the outburst. One of the
more important sources of uncertainty is the nuclear reaction data used as
input for the evolutionary calculations. A recent paper by Starrfield, Truran,
Wiescher, & Sparks (1998) has demonstrated that changes in the reaction rate
library used within a nova simulation have significant effects, not just on the
production of individual isotopes (which can change by an order of magnitude),
but on global observables such as the peak luminosity and the amount of mass
ejected. We present preliminary results of systematic analyses of the impact of
reaction rate uncertainties on nova nucleosynthesis.
