The definition of a process of conditioning by cementation of solid radioactive waste has required many works intended research optimize the composition of matrices and improved their resistance. In this work, we introduced the polymer (epoxy Novolac resin) and / or epoxy Novolac composite material in a nuclear application to assess its impact. Following a research study on the management of ion exchange resins, radioactive waste generated by the Triga Mark II reactor CNESTEN, this study is an add-in to improve the compressive strength of the matrix conditioning the ion exchange resin by the introduction of the epoxy Novolac polymer and to evaluate its impact on the die packaging.
With the aim of optimizing the formulation of the matrix of the conditioning of Resins exchanges of ions (MBD-15) considered as radioactive waste generated by the nuclear reactor TRIGA MARK II of CENM, on one hand we realized several essays by fixing the percentage of cement and by modifying the percentages of resins to be confined (0 %, 4 %, 6 %, 8 %, 10 %, 12 %, and 14 %) and that some water. On the other hand, we realized another essay to illustrate the role of an aggregate such as the sand in the matrix of the cement. The moderate answer of all the realized essays is estimated by the compression resistance of the matrix after a time of 7 days, 14 days and 28 days of seclusion. The obtained results raise us that the maximum of the quantity of the REI, which we can incorporate into a formulation without the parcel loses its resistance is 12 %. The addition of an aggregate in the matrix of cement increases the compression resistance of this one.
