Characterization of Spent Nuclear Fuel with a Differential Die-Away Instrument
2014 (English)Conference paper, Abstract (Other academic)
The Differential die-away instrument (DDA) is currently being investigated within the Next Generation Safeguards Initiative Spent Fuel project as one of the non-destructive assay techniques for spent nuclear fuel characterization and verification. In this paper we report on the progress of designing the first prototype to be deployed at Swedish central interim storage facility (CLAB) where a first set of measurements of 25 PWR and 25BWR spent fuel assemblies is proposed. We also present several working concepts of how the instrument can be customized for dedicated purposes, be it a light weight instrument for portable applications, a minimalist design for reliable and economic operations or a so-called “defectoscope” design for detailed inspection of spent nuclear fuel assemblies.
