Off-Gas Alternatives for the BRET Project
- Allied-General Nuclear Services, Barnwell, SC (United States)
A caustic scrubber and a silver zeolite adsorber systems were evaluated for iodine removal from the BRET dissolver off-gas. Both systems, backed by a silver zeolite adsorber, could perform the required iodine removal. The I-129 release from the caustic scrubber/AgZ treatment system is conservatively estimated to be 1.64 x 10-4 Ci for one FFTF campaign. For the twin AgZ adsorber system, the release is estimated to be a 1.64 x 10-5 Ci per FFTF campaign. The release through the VOG system via one silver zeolite bed is estimated to be 8.63 x 10-5 Ci/FFTF campaign. For the BRET facility operating on FFTF fuel or FFTF fuel and CRBR fuel, the dissolver off-gas system using two silver zeolite beds is the least expensive. This would not be the case for a larger facility where iodine removal requirements increase the silver zeolite usage significantly.
