SUMMARYContract for Development of Tritium Accountancy and Tracking Program • June 1st, 2010
Tritium is a radioactive isotope and a nuclear material in France, thus tritium accountancy is required from the viewpoints of nuclear material control and prevention of malicious use of radioactive isotopes. By IAEA’s definition, nuclear materials accounting is the activities carried out to establish the quantities of nuclear material present within defined areas and the changes in those quantities within defined periods. From the viewpoint of tritium security, a material balance area (MBA) is defined, which is an area into or out of which the quantity of tritium in each transfer can be determined and in which the physical inventory of tritium can be determined when necessary in accordance with specified procedures in order to establish the nuclear material balance for IAEA safeguards purposes. For the ITER nuclear facilities, a two MBA approach is more practical, one (MBA 2) is the Tritium Depot for tritium transport containers located at the Tritium Plant Building (B1 floor), and th
