The possibility of measuring sin213 using reactor neutrinos is examined in detail. It is shown that the sensitivity sin2130.02 can be reached with 40 ton yr data by placing identical CHOOZ-like detectors at near and far distances from a giant nuclear power plant whose total thermal energy is 24.3 GWth. It is emphasized that this measurement is free from the parameter degeneracies that occur in accelerator appearance experiments, and therefore the reactor measurement is complementary to accelerator experiments. It is also shown that the reactor measurement may be able to resolve the degeneracy in θ23 if sin213 and cos 223 are relatively large.
