| NKS Programme Area: | NKS-B | | Research Area: | Measurement Strategy, Technology and QA | | Report Number: | NKS-356 | | Report Title: | Standardization of Radioanalytical Methods for Determination of 63Ni and 55Fe in Waste and Environmental Samples | | Activity Acronym: | STANDMETHOD | | Authors: | Xiaolin Hou, Laura Togneri, Mattias Olsson, Sofie Englund, Olof Gottfridsson, Martin Forsström, Hannele Hironen, | | Abstract: | This report presents the progress on the NKS-B STANDMETHOD project which was conduced in 2014-2015, aiming to establish a Nordic standard methods for the determination of 63Ni and 55Fe in nuclear reactor processing water samples as well as other waste and environmental samples. Two inter-comparison excercises for determination of 63Ni and 55Fe in waste samples have been organized in 2014 and 2015, an evaluation of the results is given in this report. Based on the the results from this project in 2014-2015, Nordic standard methods for determination 63Ni in nuclear reactor processing water and for simultaneous determination of 55Fe and 63Ni in other types of waste and environmental samples respectively are proposed. Meanwhile an analytical method for determination of 55Fe in reactor water samples is also recommended. In addition, some procedures for sequential separation of actinides are presented for the simultaneous determinaiton of isotopes of actinides in waste samples are presented. | | Keywords: | Radioanalysis; 63Ni; 55Fe; standard method; reactor water | | Publication date: | 20 Jan 2016 | | ISBN: | ISBN 978-87-7893-440-6 | | Number of downloads: | 2440 | | Download: |  NKS-356.pdf |
