$gamma$ Activity and Heating of Rods in EL2 and EL3; ACTIVITE $gamma$ ET ECHAUFFEMENT DES BARRES DE EL2 ET EL3

Technical Report ·
OSTI ID:4171260

A method ia described for calculating the gamma activity of uranium rods, given the mean flux in which they are irradiated, the time they remain in the pile and the duration of deactivation. This calculation leads to numerical formulas which may be applied to the rods of the two reactors. lt allows the saturation activities to be foreseen both for EL2 and for EL3, taking into account the minimum times necessary for extraction. Measurements have been carried out, and the results are in good agreement with those foreseen by calculation. In the last section this method is used to calculate the heating of the irradiated rods.
