Drell-Yan W/Z electroweak boson production at the LHC is an essential standard candle which is used for calibration of beam luminosity and detector properties. In addition to proton-proton collisions, the LHC has measured heavy nuclei lead-lead and proton-lead W/Z production. Inclusion of these data sets in future fits can provide discriminating information of the nuclear modifications present in the Parton Distribution Functions (PDFs). We present an ongoing analysis of W/Z production in lead-lead and proton-lead collisions at the LHC using the nCTEQ15 nuclear Parton Distribution Functions (nPDFs) including uncertainties. The cross sections are calculated at NLO with the FEWZ 2.1 program at 2.76 and 5.02 TeV. We identify promising observables for the observation of the nuclear modifications.
