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.

NANO Nuclear Energy
Mr. Walker is a Nuclear Physicist and was the project lead and manager for constructing the new Rolls-Royce Nuclear Chemical Plant; he was the UK Subject Matter Expert for the UK Nuclear Material Recovery Capabilities and was the technical project manager for constructing the UK reactor core manufacturing facilities. Mr. Walker was also seconded to Rolls Royce where he modeled configurations of RR’s Zero-Power reactor to inform confidence limits for the UK’s successor submarine’s mechanical design and worked for the Rolls-Royce Nuclear Thermal Hydraulics Engineering team investigating reactor channel thermal performance to inform new reactor designs and support the safety case for reactors in current class submarines. Mr. Walker’s professional engineering experience includes nuclear reactors, mines, submarines, chemical plants, factories, mine processing facilities, infrastructure, automotive machinery, and testing rigs.
Mr. Walker has extensive experience in engineering and project management, particularly within nuclear engineering, mining engineering, mechanical engineering, construction, manufacturing, engineering design, infrastructure, and safety management. He has executive experience in several public companies, as well as acquiring and re-developing the only fluorspar mine in the United States.
Mr. Walker is also a Director of Ares Strategic Mining Inc. and holds degrees in Mechanical Engineering, Mining Engineering, and Nuclear Engineering, as well as qualifications in Project Management and Accountancy. He is a Chartered Engineer with the IMechE, a Project Manager Professional with the APM, and a Professional Engineer with the Engineers and Geoscientists BC.
