2018 Elsevier Ltd A new method based on the ultra-fine-group slowing down calculation and the temperature-perturbation-technique is proposed to obtain accurate resonance absorption reaction rate of the fuel pin with non-uniform temperature profiles. It is proved theoretically and numerically that the ...
The direct calculation of an SOC stock with a changing BD will introduce sample error when sampled to a fixed depth because different soil masses are sampled. A reduction in BD due to better management (e.g., greater porosity because of improved aggregate stability and decompaction) or the ...
in solid-oxide fuel cells, lithium-ion batteries, catalysis, biomedicine, and resistive logic devices20,21. The stability of these materials and devices under many working environments (e.g., humid air and aqueous solutions) will determine their performance and lifetime. Elemental partitioning in b...
With these errors of measurable quantities, accuracy of a subcriticality calculation is indirectly derived. Three estimation methods based on the source multiplication method, the pulse neutron method, and the exponential experiment method are presented. For three experimental methods, neutron count rate ...

Fission products (e.g.79Se,135Cs) and minor actinides can have a high radiological impact on the environment during operation and severe accidents of nuclear power plants and on the residual heat production during storage of spent nuclear fuel. Correspondingly, high attention has to be paid in...
First, Materials Studio, a material calculation software produced by Accelrys in the United States, was used to build atomic models, including normal and defective structures. Point defects were created by randomly deleting atoms on the structure (Figures 2(a) and (b)). For the line defects, ...
residual energy calculation in conventional vehicles (which is easily achievable by a fuel gauge), more effort is needed to obtain a precise E RDE result in EV applications, as the residual energy of the battery systemis not directly measurable and largely influenced by a num- ber of opera...
An SVM binary classifier (e1071 R package) is trained using a radial kernel, scaling (to zero mean and unit variance), 10-fold cross validation, and probability calculation. The probability is calculated by fitting a logistic distribution using maximum likelihood to the decision values of all bi...
In order to take advantage of the improved economics offered by these modern fuel designs while simultaneously assuring safe and reliable reactor operation, both the reload design process and the online core monitoring procedures must be based on appropriate calculation methods. The modeling of ...
