Division Spotlight
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.

Argonne’s METL gears up to test more sodium fast reactor components
Argonne National Laboratory has successfully swapped out an aging cold trap in the sodium test loop called METL (Mechanisms Engineering Test Loop), the Department of Energy announced April 23. The upgrade is the first of its kind in the United States in more than 30 years, according to the DOE, and will help test components and operations for the sodium-cooled fast reactors being developed now.

The possibility of producing the base load of both electricity and district heat for the Helsinki Metropolitan Area (HMA) utilizing nuclear energy has been investigated since 1968. At every stage of the study, it has been concluded that district heating utilizing nuclear power in combined electricity and heat production is the most economic way of heating the main part of the HMA. The studies have dealt with the economy of energy production and heat transmission as well as nuclear safety. According to the latest results, the optimum of the heat output of a 1000-MW(electric) unit is ∼800 MW if the plant is situated 50 km away from the heat load center. For further studies and realization of the plans, the cities of the HMA and the state-owned power company, the Imatra Power Company, have formed a common company for the nuclear power plant project.
