Irradiated Materials Characterization Lab

Lab Location

Idaho National Laboratory (INL)
Idaho Falls, Idaho

Associate Lab Director

Ronald A. Crone

Expertise & Research

IMCL is Hazard Category 2 nuclear facility that focuses on microstructural, thermal, and mechanical characterization of irradiated nuclear fuels and materials. IMCL’s unique design incorporates advanced characterization instruments that are sensitive to vibration, temperature, and electromagnetic interference into modular radiological shielding and confinement systems. The shielded instruments allow characterization of highly radioactive fuels and materials at the micro, nano, and atomic levels, the scale at which irradiation damage processes occur.
