For the time being fusion technology development involves relatively small quantities of tritium. Consequently, it is sufficient to apply so-called "conventional" accountancy tools. However, it is foreseeable that tritium operations-and thus the amount of tritium-will increase substantially. An advanced accountancy methodology will satisfy the resulting new requirements. In this study the advanced accountancy methodology is developed and applied to the situation envisaged with an ITER-type fuel cycle. Firstly, this task comprises modeling of fuel cycle operations, providing the "true" data of the in-process inventories. As both the fuel cycle subsystems and networking them are susceptible to changes, flexible tools of simulation are necessary. Secondly, a measurement model takes care of the true data, handles data reduction, and applies mathematical methods to confirm the final inventories on a statistical basis. Then, in a third step, the test statistics might verify whether or not tritium has been lost. |
