Abstract
Neutron flux measurement for research reactor in-core is usually using the neutron activation method. The sample in this study used an Au-197 sample. The neutron flux can be obtained by calculating the saturation activity received by the irradiated sample. In the calculation of saturation activity, there are correction factors that can affect the results of the conversion of saturation activity into neutron flux. The calculation of correction factors is carried out analytically by entering variables such as counting efficiency and calculation of uncertainty variables. From this calculation, it can be seen how much influence each component and variable of the correction factor for the saturation activity calculation on the results of neutron flux measurements in the TRIGA 2000 reactor core.
