Division Spotlight
Young Members Group
The Young Members Group works to encourage and enable all young professional members to be actively involved in the efforts and endeavors of the Society at all levels (Professional Divisions, ANS Governance, Local Sections, etc.) as they transition from the role of a student to the role of a professional. It sponsors non-technical workshops and meetings that provide professional development and networking opportunities for young professionals, collaborates with other Divisions and Groups in developing technical and non-technical content for topical and national meetings, encourages its members to participate in the activities of the Groups and Divisions that are closely related to their professional interests as well as in their local sections, introduces young members to the rules and governance structure of the Society, and nominates young professionals for awards and leadership opportunities available to members.

Article considers incorporation of AI into nuclear power plant operations
The potential application of artificial intelligence to the operation of nuclear power plants is explored in an article published in late December in the Washington Examiner. The article, written by energy and environment reporter Callie Patteson, presents the views of a number of experts, including Yavuz Arik, a strategic energy consultant.

Organic impurities in containment water, originating from various painted structural surfaces and organic containment materials, could have a significant impact on iodine volatility following an accident. To determine the effect of these impurities on iodine volatility under accident conditions, literature, experimental, and modeling studies have been conducted on1. the radiolysis of organic compounds in the aqueous phase2. thermal and radiolytic formation and decomposition of organic iodides3. dissolution of organic solvents from various painted surfaces into the aqueous phase4. hydrolysis and aqueous-gas phase partitioning of organic iodides5. iodine deposition on painted surfaces.The experimental studies consist of intermediate-scale "integrated effects" tests in the Radioiodine Test Facility and bench-scale "separate effects" tests. Recent findings from these studies and implications of these studies on the safety analysis of an accident in a nuclear power station are discussed.The studies have shown that organic impurities will be found in containment water as a result of the dissolution of organic compounds from various surface paints. These compounds can have a significant effect on iodine volatility following an accident. The main influence of containment paints on iodine behavior will arise as a result of the aqueous-phase radiolysis of dissolved organic solvents, which are leached from the painted surface by the water. The radiolysis products will decrease the sump pH and dissolved oxygen concentration, consequently increasing the overall rate of conversion of dissolved I- to volatile I2. It appears that the rates of these processes may be controlled by the dissolution kinetics of the organic compounds from the surface coatings. Moreover, organic compounds may also react thermally and radiolytically with I2 to form organic iodides in the aqueous phase. Our studies have shown that the formation of organic iodides in the aqueous phase from soluble organic compounds such as ketones, alcohols, and phenols will have more impact on the total iodine volatility than the formation of CH3I from CH4 and I2 from either the gas or the aqueous phase.
