A Probabilistic-Micromechanical Methodology for Assessing Zirconium Alloy Cladding Failure
Cladding failure of fuel rods caused by hydride-induced embrittlement is a reliability concern for spent nuclear fuel after extended burnup. Uncertainties in the cladding temperature, cladding stress, oxide la...

Scientific Bases for Cladding Credit as a Barrier to Radionuclide Release at the Proposed Yucca Mountain Repository
The performance of Zircaloy nuclear fuel cladding in the environment of the proposed Yucca Mountain (YM) high-level waste (HLW) repository is evaluated. Because the uniform aqueous corrosion/oxidation rate is ...

The Effect of Tensile Strain on AlGaAs/GaAsP Interdiffused Quantum Well Laser
In this paper, we study the interdiffusion of tensile strained GaAsyPi.y /A10 33Ga0 67As single QW structures with a well width of 60 Å. Different P concentrations in the as-grown well are chosen to obtain dif...

Accurate Modeling of the Subband and Optical Properties of Compressive Strained Quantum Wells
The effect of valence subband-mixing on the optical properties of strained and unstrained quantum wells (QWs) is analyzed theoretically. In the model developed, the orientation of the confined carrier in-plane...
