“…One of the possible ways is to use a transmutation process which could convert long-lived radionuclides to stable or shorter half-lives in order to decrease their radiotoxicity. [1][2][3] Reactor-based irradiation experiments are conducted by the French Nuclear Energy Division to study the potential of the transmutation process. 4 One of these experiments, named PROFIL-R, involved two experimental pins which contained 55 separate samples each.…”

“…Many options for waste management are discussed and one of the possible ways is the transmutation of long-lived radionuclides in fast neutron nuclear reactors. 3,4 The goal is to obtain an appreciable radiotoxicity reduction of long-lived fission products. 5 The French Nuclear Energy Division has carried out several experiments in the French fast neutron reactor Ph enix.…”

Within the framework of the research undertaken by the French Atomic Energy Commission on transmutation of long-lived radionuclides, targets of highly enriched actinides and fission products were irradiated in the fast neutron reactor Ph enix. Precise and accurate measurements of the isotopic and elemental composition of the enriched elements are therefore required. In order to obtain the uncertainties of several permil and to reduce handling time and exposure to analyst on radioactive material, the on-line coupling of ion exchange chromatography with quadrupole inductively coupled plasma mass spectrometry has been associated with the technique of the double spike isotope dilution. We present in this paper the results obtained on an irradiated sample of Europium oxide powder (enriched at 99.13% in 153 Eu). After irradiation of around 5 mg of Eu 2 O 3 powder the theoretical calculations predict the formation of several micrograms of gadolinium and samarium isotopes. In relation to the very high activity of the sample after irradiation and the very low quantity of Sm formed, the on-line ion exchange chromatography separation of Gd, Sm and Eu before Sm isotope ratio measurements has been developed for the quantification of the 152 Sm/ 153 Eu ratio. These on-line measurements were associated with the double spike isotope dilution technique after calibration of a 147 Sm/ 151 Eu spike solution. The external reproducibility of Sm isotopic ratios was determined to be around 0.5% (2s) resulting in a final uncertainty on the 152 Sm/ 153 Eu ratio of around 1% (2s). These on-line measurements present therefore a robust and high-throughput alternative to the thermal-ionisation mass spectrometry technique used so far in combination with off-line chromatographic separation, particularly in nuclear applications where characterisation of high activity sample solutions is required. 153 a Commissariat a l'Energie Atomique, DEN/DPC/SECR/LANIE, bât 391,

“…Some more detailed studies on the intercomparison of the HLW transmutation potential of dierent reactor technologies have been published [70,300,301,302,305]. These studies also agree in the advantages of fast reactor technology and hence, most concepts of transmutation reactors are based on fast systems.…”

sionalism and hard work during the experiments, I would like to highlight their kindness in making us having a agreeable stay at Belarus. I wish to acknowledge as well the institutions that have provided nancial support for the work carried out during this PhD thesis: the EU 6th Framework program through IP-EUROTRANS Contract No. FI6W-CT2005-516520 and the ENRESA-CIEMAT agreement for the Transmutation Applied to High Level Radioactive Waste.Third, I want to thank as well all the colleagues from the Nuclear Innovation Unit and Nuclear Fission Division at CIEMAT during all these years, for all that I have learned with them and all the help they have provided at many instances, which would be endless to detail. In particular, special thanks to those that have revised the manuscript: Manuel Fernández-Ordóñez, Francisco Álvarez-Velarde and Juan Blázquez. I am also indebted to the administrative and services sta at CIEMAT for their usually invisible, albeit indispensable, assistance in many daily tasks. In particular, I would like to mention the Documentation Service for their help in nding many of the bibliographic references of this thesis.And nally, last but not least, I would like to acknowledge my family for all their support during all these years.
