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 ...
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 ...

Once the user has created all the polygons and obstacles within the district, the online map-based tool automatically creates nodes based on the vertices of the polygons and assigns them numbers. Also, the tool performs a calculation to obtain the relative coordinates of the nodes, selecting a...
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...
increments of the scenario 2 baseline depth. This calculation preserved the prescribed average BD of the new time point by only expanding the initial SOC concentration. We adjusted the SOC concentration of the next time point to maintain the average SOC concentrations of the 30 cm fixed depth ...
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...
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 proposed method was applied to the calculation of collision probabilities in a two-region LWR fuel pin cell, and it was found that the collision probabilities can be calculated with an error of less than 1%, a great improvement in accuracy compared to the zero-th approximation, when the ...
