We report the discovery of RAVE J203843.2-002333, a bright (V = 12.73), verymetal-poor ([Fe/H] = -2.91), r-process-enhanced ([Eu/Fe] = +1.64 and [Ba/Eu] =-0.81) star selected from the RAVE survey. This star was identified as ametal-poor candidate based on its medium-resolution (R ~ 1,600) spectrumobtained with the KPNO/Mayall Telescope, and followed-up with high-resolution(R ~ 66,000) spectroscopy with the Magellan/Clay Telescope, allowing for thedetermination of elemental abundances for 24 neutron-capture elements,including thorium and uranium. RAVE J2038-0023 is only the fourth metal-poorstar with a clearly measured U abundance. The derived chemical-abundancepattern exhibits good agreement with those of other known highlyr-process-enhanced stars, and evidence in hand suggests that it is not anactinide-boost star. Age estimates were calculated using Th/X and U/X abundanceratios, yielding a mean age of 13.0 +/- 1.1 Gyr.
