|a A model is presented to describe the time-dependent flow and retention of stable iodine isotopes and the decay of ¹³¹I in a nuclear fuel reprocessing plant. The plant consists of 16 units of equipment such as a voloxidizer or graphite burner, fuel dissolver, solvent extractors, storage tanks, vaporizers, primary iodine sorbers, and silver zeolite. The rate of accumulation of bulk and radioactive iodine in these units and in the environment is described using 19 differential equations. Reasonable time-dependence of iodine retention factors (RFs) by the plant were calculated. RFs for a new plant in excess of 10⁶ for stable iodine and ¹²⁹I decrease to the range of 10³ to 10² as plant operating times exceed 50 to 100 days. The RFs for ¹³¹I also decrease initially, for a period of approximately 10 days, but then increase by several orders of magnitude due to radioactive decay and isotopic exchange. Generally, the RFs for ¹³¹I exceed those for stable iodine by factors of 10⁴ or more. 19 references, 13 figures, 2 tables. (DLC)
