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.

Over the preceding ten years, continual research and development has been performed on the high temperature irradiation resistant thermocouple (HTIR-TC) by the team at Idaho National Laboratories (INL) High Temperature Test Laboratory (HTTL). The HTIR-TC has the capability of achieving high temperatures up to 1600°C or more. Further, the HTIR-TC has gone through many longevity tests both in and out of pile to show the amount of drift is minimal compared standard thermocouples. Key considerations for properties and materials of the HTIR-TC have been final diameter, ductility after heat treatment, and minimizing transmutation of materials during operation. Further, heat treatment and calibration processes have been established in order to consistently produce repeatable and reliable temperature readings. The current work provides further background for the standardization process of the HTIR-TC.
