12. Investigation of final products of chemical enrichment of uranium ore Final products of chemical enrichment of uranium ore have been studied with the scanning electron microscopy. The product is uranium oxide crystals of prismatic form. Monoclinic system of crystals is the most probable. X-ray investigation of samples with Debye technique and their elemental analysis show that crystals are identical to oxidated uraninite U 4 O 9 SEM image of uranium oxide crystals Debyegram of fine uranium oxide crystals mixture 12

13. A Study of Uraninite by PIXE Technique μ-PIXE measurements were carried out at the Scanning Nuclear Microprobe facility of the Institute of Applied Physics of the National Academy of Sciences of Ukraine, Sumy. Scanning of sections of all seven fragments of characteristic size of 100…200 μm was performed by proton beam with energy E=1.5 MeV with scan region of 50×50 pixels, step of scanning of 2 μm and 4 μm.

14. Efforts in Monitoring of Trace Amounts of Transuranium Elements Isotopes The isotopes of transuranium elements are the most toxic and is usually the most long-lived component of the emissions of the Chernobyl accident and other radioactive waste storage facilities in Ukraine and neighboring countries of former Soviet Union. Of all the methods for determining the main dose- forming radionuclides ( 238,239,240 Pu, 241,243 Am) radiochemical separation of plutonium and, especially, americium is technically the most difficult, time- consuming and expensive task. In this regard, radioecological studies of pollution by isotopes of transuranium elements in Ukraine were carried out in a very limited scale: both in localisation and on isotopes content. 14

16. We can solve this problem! The Institute of Applied Physics of the National Academy of Sciences of Ukraine has unique (for countries of former USSR) high-sensitive accelerator mass spectrometer AMS-1MV «Tandetron» (by HVEE, the Netherlands) with isotopic sensitivity of 10 -15.The AMS allows determining the content of all transuranium elements in any samples. This device enables us to define all known isotopes of plutonium and other actinides ( 238, 239, 240 Pu, 241, 243 Am, 237 Np) that are in the samples, to determine their contents, ratio, and, hence, to clarify their origin. 16

17. Relevance of Establishment of Laboratory Transuranium Elements in Ukraine Establishment of Center for collective use for determination of Trace Amounts of Transuranium Elements on the basis of accelerator mass spectrometry laboratory in Institute of Applied Physics NAS of Ukraine will permit: to promote prevention of nuclear terrorism, illicit traffic and/or use of nuclear materials in Ukraine (Nuclear Forensics Program, CBRN Defense); to identify nuclear materials through the isotopic composition and concomitant elements; to study the harmful effects of the Chernobyl disaster and to provide pollution monitoring of transuranium elements in Ukraine and neighboring countries. 17

18. The Method of Project Implementation Use of accelerator mass spectrometry allows simplifying the sample preparation procedure without pre- concentration and separation of isotopes of transuranium elements. Using AMS for studies of environmental pollution permits reaching detection limit of 1.3 ppq for 240 Pu (Reports of Lawrence Livermore National Laboratory (LLL) and other literature sources). Project provides: Training specialists of the IAP at LLL for 6 months. Collaboration of specialists LLL and IAP in the optimization of the analytical mode of the accelerator mass spectrometer and improving of analytical techniques in the IAP. The proposed term of the project - 2 years. 18

19. Expected results and perspective Laboratory of transuranium elements will allow reliably identify nuclear materials, will improve the radioisotope researches. The Laboratory will be a deterrent for illicit traffic of any potentially dangerous nuclear materials in the territory of Ukraine and neighboring countries. The project provides the adaptation of existing techniques and development of new methods for determination of the isotopes concentrations of transuranium elements in the IAP NASU in collaboration with Lawrence Livermore National Laboratory (USA). 19
