“…Determination of zirconium concentration and isotope abundance is important for different applications such as life science [1], geology [2][3][4][5][6], environment [7], forensics [8] or nuclear field [9][10][11][12][13]. In nuclear applications, zirconium is used as a construction material in nuclear reactors [14] and is a fission product: the radioactive 93 Zr isotope is produced mainly by nuclear fission of uranium-235 in nuclear fuel.…”

“…Several studies for zirconium isotope measurement have been reported in literature. They are mainly two principal techniques used for this kind of measurement: multiple collector-inductively coupled plasma mass spectrometer [2][3][4]9,10] (MC-ICP-MS) and thermal ionization mass spectrometry [1,2,5,6,8,[18][19][20] (TIMS). TIMS is a reference technique for isotope measurement [21][22][23]. TIMS allows reaching isotope ratio with high measurement trueness and precision.…”

A new Thermal Ionization Mass Spectrometer (TIMS) analytical procedure was developed to measure with high accuracy the zirconium isotope abundance and concentration without molybdenum correction in nuclear samples. A zirconium selective separation using UTEVA column was used before the TIMS measurement in order to remove all possible isobaric interferences (Mo, Y, Nb and Ru) in the solution. The separated solution was then deposited onto a filament previously outgassed for 4 hours to reduce the molybdenum traces in the filament. Then, the filament was introduced into the TIMS source and was maintained for 4 hours at a current of 5 A (ionization filament) and 1.2 A (evaporation filament) in order to eliminate all molybdenum trace present in the filament and in the sample. This methodology allowed the zirconium isotope abundance determination without using the molybdenum interference correction equation. The analytical results obtained with a natural solution after separation is in good accordance with the reference values: bias lower than 0.16 % for the 90 Zr, 91 Zr, 92 Zr and 94 Zr isotope abundance, and a bias of ~0.8 % for the minor isotope (96 Zr) were observed. This zirconium abundance determination methodology was used on three nuclear samples. Then, the calibration of a 91 Zr spike solution was performed by reverse isotope dilution using a SPEX standard zirconium solution. The zirconium concentration determination was then performed on the three nuclear samples by isotope dilution using the SPEX standard zirconium solution and the 91 Zr spike solution. The final uncertainties were estimated to be lower than 1 %.

“…However, during the analysis of 93 Mo, the X-rays are absorbed by the glass or PFA container because of their low energy. Cassette et al measured the X-ray data for 93m Nb, which has the same energy as that of 93 Mo, by using a specific locally developed container for the solution sample [21]. In order to measure the X-rays from 93 Mo, development of a container or of preparation method for solid sample measurement is required.…”

“…It is produced mainly by nuclear fission of uranium 235 and neutron activation of zirconium, which can be used as the cladding of fuel elements in nuclear reactors because of its low neutron absorption cross section [4] and excellent properties of radiation-resistance. A novel method for the measurement of ultratrace 93 Zr was developed by the AMS Laboratory group at CIAE.…”
