Resumo
This work aims the final calibration of the nuclear power channels of the IPEN/MB-01 reactor using infinitely
dilute gold foils (1% Au - 99% Al), this is, metallic alloy in the concentration levels such that the phenomena of
flux disturbance, as the self-shielding factors become worthless. During the irradiations were monitored the
nuclear power channels of the reactor used to obtain the neutron flux and consequently the power operation of
the reactor. The current values were digitally acquired during each second of operation. Once the foils were
irradiated for the analysis of its induced activity it was used a detection system of hyper-pure germanium. Ally
to this experimental procedure it was used the computational code MCNP-4C as a tool for theoretical modeling
of the core of the IPEN/MB-01 reactor. Thus it was possible to determine the parameters necessary to obtain the
power operation of the reactor, such as the inverse of the thermal disadvantage factor and fast fission factor.
Thus, using the correlation between average thermal neutron flux, proportional to a power operation and the
average of the digital values of current of the nuclear channels, during the irradiations of the foils, it was
obtained the calibration of the nuclear power channels, the ionization chambers number 5 and 6 of the
IPEN/MB-01 reactor.
