Detrimental Element Analysis of Non-Metallic Materials Used in Nuclear Reactors
By: J. Foroughi, M.B. Bolduc, D.A. Rathbun
Abstract
Metals and anions that initiate or accelerate corrosion are of concern in evaluating the suitability of a non-metallic material
for use in a nuclear reactor environment. This paper describes several analysis techniques for measuring concentrations of these
detrimental elements. Chemical analysis for halogens, sulfur, and low-melting point metals by ASTM D129, E144 and D3761,
using oxygen bomb or water leaching preparation with ion chromatography (IC) and inductively-coupled plasma (ICP) optical emission
spectroscopy (OES or AES) is described. Some independent testing laboratories are approved for testing materials for use in
nuclear safety-related applications. Guidelines are offered for selecting a suitable lab, whose quality and reporting
standards must be in compliance with 10 CFR 50 Appendix B and 10 CFR Part 21 federal requirements.
