Unique QA/QC requirements for analytical chemistry at LANL

PDF Version Also Available for Download.

Description

One of the missions of group NMT-1 (Nuclear Materials Technology Division/Analytical Chemistry) at Los Alamos National Laboratory (LANL) is to provide analysis of both radioactive and nonradioactive materials to address the stockpile stewardship needs of the US Department of Energy (DOE). Trace to high levels of various constituents are measured using traditional analytical methods and state-of-the-art instrumental methods. Capabilities include Pu and U assay, wet chemistry, plasma spectroscopy, mass spectrometry radiochemistry, x-ray fluorescence, anion and cation analysis, special standards preparation, surface analysis, and gas analysis. The authors are currently developing and implementing a plan to independently assess the quality of ... continued below

Description

One of the missions of group NMT-1 (Nuclear Materials Technology Division/Analytical Chemistry) at Los Alamos National Laboratory (LANL) is to provide analysis of both radioactive and nonradioactive materials to address the stockpile stewardship needs of the US Department of Energy (DOE). Trace to high levels of various constituents are measured using traditional analytical methods and state-of-the-art instrumental methods. Capabilities include Pu and U assay, wet chemistry, plasma spectroscopy, mass spectrometry radiochemistry, x-ray fluorescence, anion and cation analysis, special standards preparation, surface analysis, and gas analysis. The authors are currently developing and implementing a plan to independently assess the quality of the analytical data produced by NMT-1. Nuclear materials of a matrix similar to the client`s samples but having different concentration levels of analytes that are representative of the client`s samples will be used. Well-characterized, stable, homogeneous materials have been identified as possible candidates for single-blind quality control (QC) samples. These materials include Pu metal, Pu oxide, uranium metal, uranium oxide, and uranium-plutonium mixed oxide with varying degrees of purity. These single-blind samples will be periodically distributed along with regular client samples to be analyzed by the above mentioned analytical methods.
