Most iodine removal system designs utilizing silver-containing solid sorbents assume only a 30 to 50% silver utilization. Based on laboratory tests, potentially 60 to 70% of the silver contained in the sorbents can be reacted with iodine. To overcome the high cost of silver associated with these materials, various approaches have been explored.

Real-Time Monitoring Tool Speeds Up Advanced Nuclear Reactor

Off-gas fission products are produced in all nuclear reactors. Iodine gas is a particular concern because it is radiotoxic, can easily vaporize and, if released, becomes airborne. The operation of molten salt reactors would require iodine be treated and scrubbed from the system as it is produced in real-time.

Literature survey: methods for the removal of iodine species …

The most promising acid-scrub process for removal of iodine species from off-gases appears to be Iodox. The most promising solid sorbent for removal of iodine species from off-gases is the West German Ag-KTB--AgNO/sub 3/-impregnated amorphous silicic acid. The tandem silver mordenite--lead mordenite sorbent system is also quite attractive.

Multinodular Goiter

Multinodular goiter (MNG) is the most common of all the disorders of the thyroid gland. MNG is the result of the genetic heterogeneity of follicular cells and apparent acquisition of new cellular qualities that become inheritable. Nodular goiter is most often detected simply as a mass in the neck, but sometimes an enlarging gland produces …
