Abstract

The conditioning of exhausted Resins Exchanging Ions (REI) (radioactive wastes generated by nuclear operations) was optimized using a full factorial experiments plan 24. Sixteen experiments with a suitable choice of four interpretable variables led to a mathematical model in the form of a first degree polynomial. After analysing the effects, this model showed that the most influential factor on the response (compression strength) is the water/cement ratio (W/C) with a positive effect of (+2.17), the second factor in order is the mixing time with a positive effect of (+1.54). The interaction between the (W/C) and the number of vibration and interaction between the (W/C) and the mixing time also have effects on the response.
