Abstract
The antineutrino detectors for the Daya Bay reactor neutrino experiment are liquid scintillator detectors designed to detect electron anti-neutrino via inverse beta interactions with high efficiency and low backgrounds. Since the antineutrino detector will be installed and immerged in water Cherenkov detector and will run for 3 to 5 years, water tightness is critical to the successful operation of the antineutrino detectors. A special seal technique was used for this purpose. Three leak checking methods have been employed to ensure the seal quality. This paper describes the sealing method and leakage testing results.
