Determination of the neutrino mass hierarchy using a reactor neutrino experiment at \ensuremath∼60 km is analyzed. Such a measurement is challenging due to the finite detector resolution, the absolute energy scale calibration, and the degeneracies caused by current experimental uncertainty of |\ensuremathΔm322|. The standard \ensuremathχ2 method is compared with a proposed Fourier transformation method. In addition, we show that for such a measurement to succeed, one must understand the nonlinearity of the detector energy scale at the level of a few tenths of percent.
