Description
We will describe the status of the Angra Project, aimed at developing an antineutrino detector for monitoring nuclear reactor activity. Nuclear reactors are intense source of antineutrinos and the thermal power released in the fission process is directly related to the antineutrino flux, making antineutrino detectors good candidates to become in the future a new safeguards tool for monitoring reactors through counting rates and spectral measurements.
The Angra experiment will use the Brazilian nuclear power plant Angra II, with 4 GW of thermal power, as a source of antineutrinos. A water Cherenkov detector of one ton target will be placed in a commercial container just outside the reactor containment, at about 30 m of the reactor core. A few thousand antineutrino interactions per day are expected. The shielding configuration and the event analysis strategies to overcome the large background induced by cosmic rays at ground level are being developed and will be presented.
