Uranium Enrichment determination

To describe the X-ray peaks, a Lorentzian broadened shape function was used, and methods were developed to reduce the number of fitting parameters for decomposing the strongly overlapping peaks using channel-energy, energy-width, and energy-efficiency calibration functions

Isotopic analyses of plutonium and low-enriched uranium mixtures with particle sizes of 0.6e3.3 mm were performed using thermal ionization mass spectrometry with a continuous heating method to verify its effectiveness for the accurate analysis of minor isotopes without sample pretreatment. The mixed particles used in this study were prepared from a mixed solution of plutonium (SRM 947) and uranium (U010, 235U 1% enriched) reference materials.

Since mid-2009, North Korea has admitted it has a uranium enrichment program and implied that it will enrich uranium on a significant scale in the near future. After years of denial, North Korea mentioned its uranium enrichment program in public statements as tensions increased following its ballistic missile test in April 2009, its May 2009 nuclear test, and the subsequent imposition of United Nations Security Council sanctions against North Korean trading entities.
