| Abstract Scope |
Assessments have been made that suggest that radioactive iodine that could evolve during used nuclear fuel reprocessing may require control efficiencies greater than 99.9% to meet regulatory air emission limits in the U.S. Granular solid sorbents have been demonstrated in "deep-bed" tests to assess the performance of granular solid sorbents for capturing iodine species in off-gas streams. Sorbents that have been tested to date include selected silver-impregnated zeolites and engineered sorbents. The multi-stage test system design has provided the ability to determine (a) the sorbent capacity, b) the sorbent capture efficiency, and (c) the mass transfer zone. Test results indicate that, for expected off-gas conditions for aqueous used fuel reprocessing, efficiencies of between 99.9 - 99.99% are possible. This work has been funded by the U.S. Department of Energy Advanced Fuel Cycle Research and Development Program Separations and Waste forms Campaign. |
