Abstract

In the frame of the accountancy measurements of the fissile materials, reliable determinations of the plutonium and uranium content in spent nuclear fuel are required to comply with international safeguards agreements. Large-sized dried (LSD) spikes of enriched U and Pu for isotope dilution mass spectrometry (IDMS) analysis are routinely applied in reprocessing plants for this purpose. A correct characterisation of these elements is a pre-requirement for achieving high accuracy in IDMS analyses. This paper will present the results of external verification measurements of such LSD spikes performed by the European Commission and the International Atomic Energy Agency.

摘要

在裂变材料的会计计量框架内，为遵守国际保障监督协定，需要对乏核燃料中的钚和铀含量进行可靠测定。为此，后处理厂通常使用用于同位素稀释质谱法（IDMS）分析的大尺寸干燥（LSD）富集铀和钚标样。对这些元素进行正确表征是在IDMS分析中实现高精度的先决条件。本文将介绍欧盟委员会和国际原子能机构对这类LSD标样进行的外部验证测量结果。
