Description
Reactor channel characterization is commonly performed by irradiation of bare and cadmium-covered
"fluence rate-monitors", avoiding as much as possible the use of irradiation vials/capsules and spacers for positioning
the monitors inside the channel.
However, in routine k0-Neutron Activation Analysis is generally necessary to pack the samples in polyethylene vials
prior to irradiation.
This work aims at studying the impact of polyethylene vials on the f (thermal-to-epithermal flux ratio)
and alpha (epithermal flux distribution) parameters through the bare, cadmium-covered and Cadmium-ratio methods.
The accuracy of each method will be discussed.
