The LUX experiment takes advantage of the self-shielding capabilities of liquid xenon to create a nearly background-free fiducial volume. This will allow for unambiguous detection of WIMP-like nuclear recoils. LUX has been designed with the goal of $<10^{-3}$~event/kg/keV/day, corresponding to $<$1~background event in 300~livedays, and a virtually background-free month-long initial science run. The ultimate 90\% exclusion WIMP limit of the experiment after a 30000~kg~day run is projected to reach 4$\times$10$^{-46}$~cm$^2$ for a WIMP mass of 100~GeV. This talk will discuss background projections from the LUX material screening program, as well as modeling of cosmogenic and intrinsic background sources in the Xe.
