RESUMO

Nuclear reactors are an abundant source of anti-neutrinos, whose spectrum is determined by the hera decay of radioactive isotopes in the nuclear fuel. As the fuel is consumed, their isotopic composition is altered, with direct consequences on the spectrum of anti-neutrlnos. Thus, detection of anti-neutrinos can be applied in monitoring the isotopic composition of fuel in nuclear reactors and their rate of consumption, on a non-intrusive and independent way from the nuclear plant operator information. In this study, we investigated the requirements in energy resolution of an anti-neutrino detector, positioned in close proximity to the reactor, enabling a precise spectroscopy to enable reconstruction of the individual contributions ofthe isotopes 235U, 238U, 239Pu and 241Pu to the total flux. To do this, we built a Monte Carlo simulations to evaluate the intrinsic energy resolution of a possible detector of the Neutrinos Angra Project. Final1y, we analyzed the simulated data using models found in article and propose a new model in an attempt to berrer adjust our data
