SHM system development for molten salt test loop Open
Ultrasonic structural health monitoring (SHM) systems can detect degrading material properties based on changing wave speeds. In harsh environments like molten salt reactors and allied test loops, the transducers must be sufficiently robus…

A statistical representation of bond coating oxidation under environmental barrier coatings Open
Environmental barrier coatings (EBCs) protect SiC‐based ceramic matrix composites (CMCs) in turbine hot sections from high‐temperature volatilization in combustion gases. The formation of a SiO 2 thermally grown oxide (TGO) is expected und…

Evaluation of the Mechanical Properties of Cast and Wrought CF8C-Plus Relevant to ASME Code Case Qualification Open
The mechanical behavior of a cast form of an advanced austenitic stainless steel, CF8C-Plus, is compared with that of its wrought equivalent in terms of both tensile and creep-rupture properties and estimated allowable stress values for pr…

Summary of Structural Alloy Compatibility in Supercritical CO2 at 450°-800°C Open
Supercritical CO2 (sCO2) is of interest as a working fluid for several concepts including the direct- fired Allam cycle as a low-emission fossil energy power cycle. Over the past 10 years, laboratory exposures at 300 bar sCO2 have found re…

High Temperature Mechanical Behavior of Refractory Alloys with Digital Image Correlation Open
Gas turbine efficiency is typically limited by the maximum allowable temperature for components at the inlet side and in the hot gas flow. Refractory alloys and SiC/SiC ceramic-matrix composites (CMCs) are promising candidates for advancin…

Assessing the Impact of Molten Halide Salts on Creep of Structural Alloys at 650°-750°C Open
There is a critical lack of data on the mechanical behavior of candidate structural materials for advanced nuclear reactors under molten halide salt environments. Limited legacy data from the molten salt reactor experiment (MSRE) program s…

Materials Assessment for FLiBe Fusion Blankets Open
This evaluation was prepared at the request of DOE-FES and expands on an earlier evaluation prepared by Wilson, Wiffen and Keiser in 2015 (attached as Appendices A and B). Additional useful information for materials in fission molten salt …

NSUF BOILER Pre-Irradiation Characterization and High Flux Isotope Reactor Experiment Design Open
Alumina-forming austenitic (AFA) stainless steels have emerged as a candidate alloy because of their high-temperature strength, formability, cost, and compatibility with primary coolants for lead-cooled fast reactors (LFRs). This class of …

Understanding Environmental Barrier Coating Lifetimes and Performance for Industrial Gas Turbines Open
Hydrogen or hydrogen blend fuels are expected to replace natural gas in land-based industrial gas turbines (IGTs) to support a greener power economy. Silicon carbide (SiC) base ceramic matrix composites (CMCs) are considered for replacemen…
