CFTSIM-ITER DYNAMIC FUEL-CYCLE MODEL

Dynamic system models have been developed for specific tritium systems with considerable detail and for integrated fuel cycles with lesser d etail (e.g. D. Holland, B. Merrill, Analysis of tritium migration and deposition in fusion reactor systems, Proceedings of the Ninth Symposi um Eng. Problems of Fusion Research, October (1981); M.A. Abdou, E. Vo id, C. Gung, M. Youssef, K. Shin, DT fuel self-sufficiency in fusion r eactors, Fusion Technol. 9 (1986) 250-285; G. Spannagel, P. Gierszewsk i, Dynamic tritium inventory of a NET/ITER fuel cycle with lithium sal t solution blanket, Fusion Eng. Des. 17 (1991) 271-277; W. Kuan, M.A. Abdou, R.S. Willms, Dynamic simulation of a proposed ITER tritium proc essing system, Fusion Technol, 28 (1995) 664-671). In order to provide a tool to understand and optimize the behavior of the ITER fuel cycle , a dynamic fuel cycle model called CFTSIM is under development. The C FTSIM code incorporates more detailed ITER models, specifically for th e important isotope separation system, and also has an easier-to-use g raphical interface. This paper provides an overview of CFTSIM Version 1.0. The models included are those with significant and varying tritiu m inventories over a test campaign: fueling, plasma and first wall, pu mping, fuel cleanup, isotope separation and storage. An illustration o f the results is shown. (C) 1998 Published by Elsevier Science S.A. Al l rights reserved.
