Development and automation of chemical analytical procedures for the determination of non-gamma-emitting radionuclides in radioactive waste (DACAPO), Final report

Project ID: FIKW-CT-2000-00022
Funded under: FP5-EAECTP C

Abstract

The determination of non-gamma-emitting radionuclides in radioactive waste packages is divided into four main steps: sampling, disintegration of the waste matrix, separation of the radionuclides, and the measurement.
Samples can only be taken from small local areas due to the large volume of the waste packages. Statistical evaluations of different local samples and empirical parameters are necessary to achieve an assumption for the content of a whole package. A development of a tool set will be started, which provides the needs for a probable estimation of the total radionuclide inventory. These tools should take into account results from non-destructive tests about the density and gamma-emitting radionuclide distribution in the waste package.
After sampling the waste matrix of the sample must be dissolved. Advanced disintegration methods for difficult matrices like incineration ashes, graphite or different organic material will be developed to minimise the amount of insoluble residues. Furthermore the determination of alpha-nuclides in fine powdered solids will be tested to determine the residual alpha-nuclides in the residues of the dissolved waste.
