The ANGRA Neutrino Project

We present the status of the Angra Neutrino project, describing the development of an antineutrino detector aimed to monitor nuclear reactor activity. The experiment will take place at the Brazilian nuclear power plant located in Angra dos Reis. The Angra II reactor, with 4GW of thermal power, will be used as a source of antineutrinos. We expect to observe about one thousand events per day with a detector of one ton scale, placed at about 60 meters of the reactor core. We intend, in a first step, to use the measured neutrino event rate to monitor, with a few per cent accuracy, the thermal power delivered by the reactor. In a second step we intend to determine the fuel isotopic composition through a precise neutrino energy spectrum measurement. In addition to the safeguards issues the project will provide an alternative tool to have an independent control of the reactor delivered thermal power.
