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.
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.
2020 ANS Virtual Winter Meeting

UWC 2020: A call for transformational change
Bowing to current COVID-19 realities but buoyed by the success of June’s virtual Annual Meeting, ANS event planners returned to the virtual realm for this year’s Utility Working Conference. Originally scheduled for August 9–12 at Marco Island, Fla., the condensed event was held Wednesday, August 11, wherever registrants’ computer devices happened to be located.
In addition to 26 educational sessions and workshops, UWC 2020 featured an opening plenary session titled “Achieving Transformational Change: A leadership discussion,” moderated by Bob Coward, MPR Associates principal officer and ANS past president (2017–2018). Plenary panelists included representatives from three utilities—Arizona Public Service (APS), Exelon, and Xcel Energy—plus the Institute of Nuclear Power Operations (INPO) and the Nuclear Regulatory Commission.

This paper examines the main features of the gas purification process from tritiated water vapor at any relative humidity using water phase isotope exchange. The experimentally evaluated overall mass transfer coefficient (KOG) for structured CY black packing manufactured by SULZER Chemtech (Switzerland) was used as the main performance parameter of the method. The obtained KOG dependencies on various process parameters (temperature, water and gas flows, and their ratio) demonstrate that column operation in adiabatic mode is preferable for the detritiation of gas at any relative humidity. Under comparable conditions, KOG does not depend on the column diameter in the investigated range. A comparison of the main characteristics of the developed technology with those of the technology based on water vapor adsorption on molecular sieves shows clear advantages in terms of energy, operating cost, and detritiation degree with the same amount of tritiated water produced as a radioactive waste.
