Determination of .sup.93Zr in nuclear power plant wastes

A radioanalytical method (based on separation using UTEVA columns and ICP-MS measurement) has been used for determination of .sup.93Zr in 37 nuclear power plant samples. As .sup.93Nb might affect the detection of .sup.93Zr, Monte Carlo activation model was used to calculate the expected .sup.93Zr/.s...

Zusammenfassung:	A radioanalytical method (based on separation using UTEVA columns and ICP-MS measurement) has been used for determination of .sup.93Zr in 37 nuclear power plant samples. As .sup.93Nb might affect the detection of .sup.93Zr, Monte Carlo activation model was used to calculate the expected .sup.93Zr/.sup.natZr mass ratio, which was compared to measured ones. It was found, that a decontamination factor of 10.sup.3 is sufficient to get a measurement uncertainty of less than 10%.
