TLDR
In this paper, a comparison of a range of commercial and model alloys, conventional austenitic steels do not have sufficient oxidation resistance with only ∼18Cr-10Ni, and higher alloyed type 310 stainless steel is protective but Ni is not a desirable alloy addition for this application.About:

Current Thoughts on Reactive Element Effects in Alumina-Forming Systems: In Memory of John Stringer
TL;DR: In this paper, the effect of reactive element dopants on high-temperature oxidation behavior in commercial alloys and coatings is reviewed. And some thoughts are provided on optimizing the reactive element benefit and modeling oxidation of RE-doped alloys.
Journal ArticleDOI
Neutronic analysis of candidate accident-tolerant cladding concepts in pressurized water reactors
TL;DR: In this article, the neutronics of alternate cladding materials in a pressurized water reactor (PWR) environment were analyzed and the associated neutronics penalty/advantage, changes in reactivity coefficients, and spectral variations once a transition in the cladding was made.

Irradiation-enhanced α′ precipitation in model FeCrAl alloys
Philip D. Edmondson,Samuel A. Briggs,Samuel A. Briggs,Yukinori Yamamoto,Richard H. Howard,Kumar Sridharan,Kurt A. Terrani,Kevin G. Field +7 more
TL;DR: In this paper, the compositional influence on the formation of irradiation-induced Cr-rich α′ precipitates using atom probe tomography was investigated and the average cluster Cr content ranged between 51.1 and 62.5% dependent on initial compositions.

Experimental observations in support of the dynamic-segregation theory to explain the reactive-element effect
TL;DR: In this article, a model was developed to explain the effects associated with the addition of reactive elements that is based on the segregation of reactive-element ions to scale grain boundaries and the metal-oxide interface.
Journal ArticleDOI
Structural materials challenges for advanced reactor systems
TL;DR: In this paper, the authors give a brief overview of various materials that are essential to establish advanced systems feasibility and performance for in pile and out of pile applications, such as ferritic/martensitic steels (9-12% Cr), nickel based alloys (Haynes 230, Inconel 617, etc.), oxide dispersion strengthened ferritic and martensite steels, and ceramics (SiC, TiC, etc.).

Oxide dispersion-strengthened steels: A comparison of some commercial and experimental alloys
TL;DR: In this article, the differences and similarities of different ODS steels are explained in terms of the microstructures of the steels, and observations are explained using the properties of the ODS micro-structures.

Paralinear Oxidation of CVD SiC in Water Vapor
TL;DR: In this article, the long-term degradation rate of CVD SiC is determined by the volatility of the silica scale, which is observed as the water vapor oxidized the SiC and simultaneously volatilized the scale.
Journal ArticleDOI
The Effect of Oxide Volatilization on the Oxidation Kinetics of Cr and Fe‐Cr Alloys
TL;DR: In this paper, the authors derived equations which describe the oxidation behavior of a system in which both diffusive and gas/oxide interface processes occur simultaneously, and applied these equations to the oxidation of Cr and Fe-Cr alloys.
