Abstract: I will discuss the proposed experiment to search for the neutrino mixing parameter $\sin22\theta_{13}$ in the electron anti-neutrino flux of the Braidwood Nuclear reactors. The talk will focus on the ongoing research and development into the experimental design and analysis methods required to make a precision measurement of the of the mixing angle at the 0.01 level. The main issues involve the relative calibration of near and far detectors and the amelioration of backgrounds.
