Energy spectra of reactor neutrinos at KamLAND

The upcoming reactor neutrino experiment, KamLAND, has the ability to explore the large mixing angle solution to the solar neutrino problem. Here, we investigate the precision to which KamLAND should be able to measure these parameters, utilizing the distortion of the energy spectrum of reactor neutrinos. Incomplete knowledge of the fuel composition of the reactors will lead to some error on this measurement. We estimate the size of this effect.
