Hydrothermal Corrosion of SiC Coupons Suppressed by Magnetron Sputtered Cr Coatings. [PDF]
Scanning, 2022 SiC‐based components are sometimes susceptible to aqueous dissolution in LWR coolant environments. To address this issue, ~10 μm thick Cr coatings was deposited on reaction‐bonded silicon carbide (RBSC) plates by magnetron sputtering. Corrosion behavior of Cr‐coated SiC and ‐uncoated SiC coupons was studied by immersing in autoclave (345°C and 16.5 MPa)

Solubility and diffusivity of hydrogen and its isotopes in the BeO system
Journal of the American Ceramic Society, Volume 106, Issue 8, Page 5005-5021, August 2023., 2023 Abstract This work revisits hydrogen insertion in the wurtzite beryllium oxide in order to fill the gap in scientific knowledge regarding the diffusion coefficients of the different chemical states of hydrogen (neutral, charged, or molecular). Both first‐principle and macroscopic models were used to this end.

Daily Load‐Follow Operation in LEU+‐Loaded APR1400 Using Mode‐K+ Control Logic
International Journal of Energy Research, Volume 2023, Issue 1, 2023., 2023 This study evaluates the efficacy of the mode‐K+ control logic for daily load‐follow operation (DLFO) in a two‐batch LEU+ fuel‐loaded APR1400 reactor with an accident tolerant fuel (ATF) cladding. The objective is to assess the performance of the control strategy under various operational conditions including high burnup.
