Diffusion Bonding Characterization

Research Goal 1. Tensile specimens prepared from diffusion-bonded block of 316/316L SS2. Micrograph showing good grain growth across the diffusion bond3. Small defects in bond area may not impact overall strength—but could lower design life, due to crevice corrosion Diffusion bond strength, defects, and corrosion behavior must be understood before they can [...]

Nuclear Energy Systems Laboratory (NESL) / Transient Nuclear Fuels Testing

Sandia National Laboratories is home to the United States’ only operational pulsed nuclear reactor capable of a comprehensive range of transient nuclear fuels testing. The Annular Core Research Reactor (ACRR) was specially designed to provide high power pulses (up to 300-MJ) in very short amounts of time (6-millisecond pulse-width), which allows the ACRR to compete [...]
