Reactor Neutrino Experiments

Precisely measuring ${\theta }_{13}$ is one of the highest priority in neutrino oscillation study. Reactor experiments can cleanly determine ${\theta }_{13}$. Past reactor neutrino experiments are reviewed and status of next precision ${\theta }_{13}$ experiments are presented. Daya Bay is designed to measure ${\sin }^{2}2{\theta }_{13}$ to better than 0.01 and Double Chooz and RENO are designed to measure it to 0.02-0.03. All are heading to full operation in 2010. Recent improvements in neutrino moment measurement are also briefed.
