“…These materials aim to increase high-temperature steam oxidation resistance versus the reference zirconium-based cladding materials that failed at Fukushima (43). In addition, high-performance fuel materials that enhance thermal properties are under consideration (44), such as thermal diffusivity, and improved retention of radioactive fission products (45), aiming to increase safety in severe accidents. The development of new materials for the extreme environment of a nuclear reactor is aiming to solve various scientific, regulatory, and operational challenges (39).…”

“…The most flexible advanced reactor technology options for potential process heat applications are those with coolant outlet temperatures >700°C (45). Depending on the particular implementation, these technologies may include the high temperature gas-cooled reactor (HTGR), liquid metal reactor (LMR), and fluoride salt-cooled high temperature reactor (FHR).…”

We review future global demand for electricity and major technologies positioned to supply it with minimal greenhouse gas (GHG) emissions: renewables (wind, solar, water, geothermal, and biomass), nuclear fission, and fossil power with CO2 capture and sequestration. We discuss two breakthrough technologies (space solar power and nuclear fusion) as exciting but uncertain additional options for low-net GHG emissions (i.e., low-carbon) electricity generation. In addition, we discuss grid integration technologies (monitoring and forecasting of transmission and distribution systems, demand-side load management, energy storage, and load balancing with low-carbon fuel substitutes). For each topic, recent historical trends and future prospects are reviewed, along with technical challenges, costs, and other issues as appropriate. Although no technology represents an ideal solution, their strengths can be enhanced by deployment in combination, along with grid integration that forms a critical set of enabling technologies to assure a reliable and robust future low-carbon electricity system.

“…Many advanced fuel concepts rely on composite materials. [14][15][16] While for many design and safety analyses the averaged value of thermal conductivity is sufficient, some analyses require spatially resolved measurement of conductivity. This applies to conditions where the exact temperature distribution is critical or where one is tasked with development and validation of model with predictive capability.…”

Thermal transport in materials used for energy applications is a physical process directly tied to performance and reliability. As a result, a great deal of effort has been devoted to understanding thermal transport in materials whose ability to conduct heat is critical. Here, our objective is to discuss the utility of laser-based thermoreflectance (TR) approaches that provide microscale measurement of thermal transport. We provide several examples that implement the TR technique to investigate thermal transport in materials used in nuclear energy applications. First, we discuss utility of this technique to measure thermal conductivity in ion irradiated ceramic materials during investigations where the primary objective is to understand the impact of radiation induced crystalline structure defects on thermal transport. We also present the capability of TR approach to resolve thermal conductivity of each layer in tristructural isotropic fuel, silicon carbide fiber composites, and 2nd phase precipitates in uranium silicide. Finally, the ability to measure interface thermal resistance between adjacent layers in composites is demonstrated.

“…Fully ceramic microencapsulated fuels consist of TRISO fuel particles embedded in a SiC matrix, (Figure 45) with their manufacture first described by Snead in 2010 (Snead et al, 2011) and more rigorously presented by Terrani in 2012 (Terrani et al, 2012a). A TRISO particle consists of a spherical fuel kernel that is coated with successive layers of porous carbon (buffer layer), a dense inner pyrocarbon (IPyC), CVD SiC, and an outer pyrocarbon (OPyC) layer.…”
