Abstract

Chromium-coated silicon carbide fiber-reinforced ceramic matrix composites are potentially applicable to accident tolerant fuel cladding in light water reactors. Cr-coated silicon carbide composite, chemical vapor deposited silicon carbide, and pure Cr-metal were oxidized in 100% steam at atmospheric pressure for 4 hours using a thermogravimetric analyzer. Post-oxidation chemical analysis, phase identification and microstructural characterization indicates that the Cr coating layers did not adversely affect silicon carbide substrate under these conditions.

Steam oxidation of chromium corrosion barrier coatings for sic-based accident tolerant fuel cladding

Journal Article Kane, K.; Stack, P.; Mouche, P.; ... - Journal of Nuclear Materials

SiC-based materials are currently being considered for accident tolerant fuel (ATF) cladding, however, there are concerns regarding hydrothermal corrosion rates and hermeticity. These issues may be addressed with the utilization of a Cr corrosion barrier coating (CBC) but the interaction of Cr with SiC under loss of coolant accident (LOCA) conditions needs to be investigated. In the present work, Cr coatings were deposited onto chemically vapor deposited (CVD) SiC with either high power impulse magnetron sputtering (HiPIMS), cathodic arc (CA), or a combination of both. Annealing and steam thermogravimetric analysis (TGA) was used to study reaction product formation with andmore »« less

Thermal Conductivity and Diffusivity for SiC Fibers for Use in ATF Cladding Composites

Journal Article Munro, Troy; Ban, Heng; Xing, Changhu; ... - Transactions of the American Nuclear Society

As part of the accident tolerant fuels (ATF) initiative, there is a need to understand the thermophysical properties of cladding for these fuels. One potential cladding material is silicon carbide (SiC) ceramic matrix composite reinforced with SiC fibers because of the corrosion resistance, resistance to hydrogen formation, high bulk thermal conductivity, and favorable mechanical properties of SiC. However, data about the thermal properties of individual SiC fibers in these composites is absent in the literature. This paper presents the measured axial thermal conductivity and thermal diffusivity of a leading SiC fiber (HiNicalon Type S) via a thermal measurement technique (transientmore »« less
Development of SiC-based Cladding for Accident Tolerant Fuels

Journal Article Katoh, Yutai; Ang, Caen; Koyanagi, Takaaki; ... - Transactions of the American Nuclear Society

Fuels and core structures in current light water reactors (LWR's) are vulnerable to catastrophic failure in severe accidents. This vulnerability is attributed primarily to the rapid oxidation kinetics of zirconium alloys in a water vapor environment at very high temperatures. Alternative materials to zirconium alloys with reduced oxidation kinetics are sought to enable enhanced accident-tolerant fuels and cores. Among the candidate alternatives, silicon carbide (SiC) - based materials, in particular continuous SiC fiber-reinforced SiC matrix ceramic composites (SiC/SiC composites), are considered to offer outstanding safety benefits. The primary objective of this work is to provide with updated overviews of themore »« less
Issue Update to LWR SiC/SiC Cladding Handbook of Properties

Technical Report Koyanagi, Takaaki; Katoh, Yutai; George, Jacobsen; ...

This report aims to provide properties data of silicon carbide (SiC) fiber–reinforced SiC matrix (SiC/SiC) composites for use in modeling for their application as accident-tolerant fuel cladding for light water reactors (LWRs). The properties data presented are specifically for geometries relevant to fuel cladding tubes, although many properties can be derived or predicted based on data from planar geometry specimen data. This report presents various properties, including mechanical properties, thermal properties, chemical stability under normal and off-normal operation conditions, hermeticity, and irradiation resistance. Table S.1 provides a high level summary of those properties mainly for nuclear-grade SiC/SiC composites fabricated viamore »« less

PIE of nuclear grade SiC/SiC flexural coupons irradiated to 10 dpa at LWR temperature

Technical Report Koyanagi, Takaaki; Katoh, Yutai

Silicon carbide fiber-reinforced SiC matrix (SiC/SiC) composites are being actively investigated for accident-tolerant core structures of light water reactors (LWRs). Owing to the limited number of irradiation studies previously conducted at LWR-coolant temperature, this study examined SiC/SiC composites following neutron irradiation at 230–340°C to 2.0 and 11.8 dpa in the High Flux Isotope Reactor. The investigated materials are chemical vapor infiltrated (CVI) SiC/SiC composites with three different reinforcement fibers. The fiber materials were monolayer pyrolytic carbon (PyC)-coated Hi-NicalonTM Type-S (HNS), TyrannoTM SA3 (SA3), and SCS-Ultra^TM (SCS) SiC fibers. The irradiation resistance of these composites was investigated based on flexural behavior,more »« less
