In 1977, Mikaelyan proposed that the detection rate of antineutrino reactor of a nuclear power plant of a measure of the energy produced by the reactor, due to the proportionality between the number of antineutrino and the number of fissions. It also showed that the shape of the spectrum of these particles could provide information on the isotopic composition of the nuclear fuel during its burning. This discovery raised the neutrino status of "ghost particles" to the condition of cornerstone" in particle physics. Studies related to neutrino are cutting edge technology especially when it comes to nuclear safeguards - a theme that serves the purposes of the International Atomic Energy Agency program (IAEA) to develop new techniques for control of non-proliferation of nuclear weapons. The Neutrino Project Angra has the distinction of being an experiment in a container placed outside the reactor building, on the surface, with the Cherenkov detector antineutrinos water-based doped with gadolinium subject to noise existing cosmic rays at sea level. In this work a computer simulation to verify the possibilities of removing these noises, with the least possible loss of information and extract the antineutrinos signal, thereby monitoring the operation of the reactor. It will also be performed to update the computational geometric model of the detector as well as the simulation to validate this new geometry.
