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 fabrication of special components and hardware and the assembly of the grid-spaced bundle for the gas-cooled fast breeder reactor (GCFR) F-5 (X317) irradiation experiment now being irradiated in row 5 of the Experimental Breeder Reactor II are described. The F-5 experiment consists of 31 fueled rods and six coolant bypass tubes for the initial loading. The components fabricated and assembled by General Atomic Company are ribbed cladding, UO2 blanket pellets (80% ± 2% TD), fission product traps, dosimeters, insulated flow bypass tubes, grid spacers, specially shaped axial spacer tubes, a thermal shield/ orifice/flow mixer, a bundle attachment ring, hexagonal tubes with key slots for rod holddown, a rail assembly with attachment to the bottom subassembly shield, dummy fuel rods for flow testing, and assembly of the grid-spaced bundle including check-fit into the flow duct. A variety of fabrication methods, including powder pressing, sintering, outer diameter grinding, thread grinding, metal forming, machining, chemical milling, electrical discharge machining, and tungsten inert gas welding, were used to produce the components.
