Femto-second Laser’s Enabling New Length Scale Fabrications for Rapid Post Irradiation Examination of Materials: Concluding LDRD Project Poster

Mechanical testing campaigns are required to qualify materials for advanced reactor conditions, yet economical and safety limitations restrict the number of standardized mechanical tests that can be performed. Reducing the size of the sample is one approach to addressing these challenges and to accelerating testing. Previous research has shown that smaller mechanical test samples produce […]

An Integrated Approach to Examining Fuel-Cladding Chemical Interaction in U-10Zr Metallic Fast Reactor Fuels: Coupling Machine Learning with Electron Microscopy and Local Mechanical Properties Analysis

Metallic U-Zr nuclear fuel alloy has regained interest as a promising candidate for next generation sodium-cooled fast reactors. Recent studies and technology assessments have identified several areas where improvements, enhanced knowledge, and reliable data are needed to bolster the U-Zr fuel design basis for qualification and commercial use. One of the most constraining phenomena affecting […]

Small-scale Mechanical Testing and Characterization of Fuel-cladding Chemical Interaction between a Ferritic/martensitic HT9 Cladding and Advanced U-based Metallic Fuel Alloy

Fuel cladding chemical interactions (FCCI) occurred on the interface between the nuclear metal fuel and cladding is the primary cause of cladding wastage, weakening cladding mechanical integrity, and placing fuel and cladding at risk. Although the microstructural and phase information of FCCI has been fairly understood, mechanical properties remain less studied due to limited reaction […]
