A novel brazing approach for joining SiC-based fuel cladding is a promising technology for enhanced accident-tolerant nuclear fuels.

Cold spraying is a potentially attractive method for producing accident tolerant fuel cladding, near-net shape nuclear reactor components, and nuclear fuel storage canisters.

Development of new, radiation-tolerant materials that maintain the structural integrity and safety margins over the course of a nuclear power reactor’s service life requires the ability to predict degradation phenomena. Modern post-irradiation examination methods make use of specialized high-flux test reactors and dedicated characterization facilities to limit occupational exposure and prevent the spread of radioactive contamination. This article illustrates the use of these advanced techniques to characterize precipitates in neutron-irradiated Fe-Cr-Al alloys.

The corrosion of structural materials and control of coolant chemistry are key factors that impact the lifetime of nuclear reactors and the development of future reactors. This article reviews corrosion issues in four reactor concepts that use vastly different coolant types: light water reactors, lead fast reactors, high temperature gas-cooled reactors, and fluoride salt-cooled high temperature reactors.

A new fusion cladding process that uses high-intensity arc lamps can produce pinhole free, smooth, uniform coatings as thick as 15 mm from various feedstock materials. This article briefly describes the process and the corrosion, wear, and high-temperature behavior of fusion claddings designed for oil and gas pipelines and related components.

Laser powder bed fusion (LBFP) additive manufacturing is a potential route for the rapid qualification of new materials for use in nuclear reactor design. Process anomalies such as spatter particles can induce lack of fusion (LOF) voids that may adversely affect the material's mechanical performance. This examination of the spatter particle process in a nickel superalloy using X-ray computed tomography and optical microscopy was conducted to identify possible causes for the formation of LOF voids and other variations during LBPF processing.

Beryllium won a lengthy competition as the material of choice for the mirrors on the James Webb Space Telescope, set to launch in 2018. This article documents the development history leading up to that decision. It took decades to perfect powder atomization and HIP'ing processes to make optical-grade beryllium components homogeneous, isotropic, polishable, thermally and dimensionally stable, and above all, predictable.

Concentrating solar-thermal power with thermal energy storage can provide renewable energy for electricity or industrial processes at any time of day. The U.S. Department of Energy (DOE) has made significant research investments to increase the operating temperature of solar-thermal systems, which increases overall efficiency, but materials science challenges remain to affordably manufacture and commercialize key components.
