The long-lived radionuclide ^18F is synthesized in nova outbursts and its decay may serve as an observational tracer of the explosion mechanism. Because the ^18F(p,α)^15O reaction is the dominant destruction mechanism for ^18F, the flux of gamma rays from ^18F decay is very sensitive to the rate of this reaction. A revised ^18F(p,α)^15O rate was determined from recent ORNL measurements of ^1H(^18F,p)^18F and ^2H(^18F,p)^19F, combined with a reanalysis of archival ^15N(α,α)^15N data. We used this new rate in nova element synthesis calculations and compared new predictions of the synthesized abundance ^18F (and other nuclides) to that obtained using the two most recent (p,α) rates. We used a post- processing approach with temperature and density histories of 28 zones of ejected material determined from separate hydrodynamics calculations. The implications for satellite observations of novae will be discussed. These calculations were performed and visualized with the Computational Infrastructure for Nuclear Astrophysics, an online suite of codes available at nucastrodata.org.
