ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

Using the computer code SOLGASMIX-PV, thermodynamical equilibrium concentrations of the iodine species in the gaseous systems Ag-I-H-O and Ag-Cs-I-H-O were calculated under experimental conditions resembling those of hypothetical severe light water reactor accidents. These calculations indicate that in a temperature range up to 1800°C AgI would be a thermodynamically stable species, which suggests that silver, originating from the evaporation of the control rods, could act as a potential sink for fission iodine by converting it to water insoluble Agl. The efficiency of this process depends on the relative concentrations of silver and iodine and is subject to the kinetics involved.
