In a nuclear reactor, one of the most important parts is the cladding, which is used to cover the fuel rod. The cladding will face many factors that impact the mechanical structure of the materials while in operation due to its position between the reactor coolant and the nuclear fuel. This cladding should be made of highly corrosion-resistant material with low thermal neutron absorbance.

The development of Generation IV Sodium-cooled Fast Reactors (SFRs) presents a crucial challenge in the form of Core Disruptive Accidents (CDAs). Boron migration is a significant concern in CDA evaluation since the eutectic reaction between boron carbide (B4C) and Stainless Steel (SS) can lead to forming a molten pool that could potentially relocate widely in the core, increasing the neutron...

—This study presents the computing stress intensity factors (SIF) due to mechanical
stress generated under tensile loading, regarding semi-elliptic surface crack initiated inside a
finite plate. The analysis is further extended to study the effect of mechanical stresses on SIF for
a reactor pressure vessel (RPV) having an elliptic corner surface crack at the location of the...

The author has recently developed a model to predict an upper-bound fatigue crack growth (FCG) rate for a metastable stainless steel immersed in various hydrogenated environments at ambient temperature and proposed that the high-frequency regime behavior is governed by hydrogen diffusion and can be adequately described by da/dN ∝ 1/(f) where  varied depending on the alloy microstructure,...

Nuclear reactor pressure vessel is a critical component of any nuclear power plant. The vessel is a thick wall container that withstands internal pressure caused by the reactor activity. This also plays important role to provide necessary barrier to keep radioactive materials out of the environment. Considering the functions, high strength low steel is usually proper candidate for making the...

The molten salt nuclear reactors, as an innovative type of Gen IV reactors, have a great
potential due to their safety and efficiency. However, the synergetic effects of irradiation and
corrosion of structural materials is not a fully explored area. Using a novel simultaneous
corrosion-irradiation facility, a FLiNaK molten salt in a pure nickel corrosion cell is exposed to a
proton...
