The introduction of the verification technology and method for UF6 Cylinders

This paper provides the NDA technology and method to verify the contents of the UF6 cylinder at the nuclear fuel fabrication plant. The method is to meet the Agency's safeguards goals. The KNFC (Korea Nuclear Fuel Co. Ltd.) imports UF6 cylinders that are enriched at the foreign enrichment plants, according to requirements by KHNP (Korea Hydro and Nuclear Power Co. Ltd.). Then they are stored in the UF6 storage before transferring in the vaporization process. Therefore, the verification of uranium enrichment of UF6 cylinders is very important issue for the International Atomic Energy Agency (IAEA) and Korea Institute of Nuclear Nonproliferation and Control (KINAC) to verify all foreign receipts of low enriched uranium (LEU) needed for all LWRs. This paper introduces the technology and method necessary for verification of UF6 Cylinders for safeguards purposes and verification results for national safeguards inspection
