We have developed the new method for estimating terrestrial SER based on simulation coupled with one-time irradiation using a conventional neutron source. This method has been validated using 65-nm planar SRAMs. However, with the ongoing progression of process shrinkage and the increasing adoption of devices fabricated with newer processes, there is a growing demand for further experimental validation of the terrestrial SER estimation method for these advanced processes. In this work, we validated the estimation method for 12-nm 1-fin FinFETs and 28-nm planer SRAMs. The SERs estimated by our method were consistent with the SERs measured using a white neutron beam at RCNP within 28% error.

Times Cited Count：11 Percentile：33.96(Engineering, Chemical)To reduce the amount of sample particles required for the measurement of particle flowability, a simple method has been developed through experimental research. The principle of this measurement is based on the vibrating tube method. The sample particles used in the experiment were pulverized ZrO
and granulated WO
with different concentration of fine particles. After a small amount of sample was put into a tube, vibration was applied at a constant frequency and amplitude and the mass of particles discharged from the tube was measured at constant time intervals. The experimental results showed that the minimum sample amount required for the measurement to evaluate the particle flowability was 10 g or less. The factors to evaluate the flowability in this simple method were the flow time and the characteristic mass flow rate.

The initial oxidation on high-index silicon surfaces with (113) and (120) orientations at 820 K has been investigated by real-time X-ray photoemission spectroscopy (Si 2p and O 1s) using 687 eV photons. The time evolutions of the Si
(n=1-4) components in the Si 2p spectrum indicate that the Si
state is suppressed on high-index surfaces compared with Si(001). The O 1s state consists of two components, a low-binding-energy component (LBC) and a high-binding-energy component (HBC). It is suggested that the O atom in strained Si-O-Si contributes to the LBC component. The reaction rates are slower on high-index surfaces compared with that on Si(001).

Times Cited Count：7 Percentile：28.18(Engineering, Chemical)The flowability of coarse particles has been experimentally investigated using the vibrating tube method, to evaluate the applicability of this method to MOX (mixed oxide of PuO and UO) particles which are nuclear fuel used for electric power production. Five sizes of non-radioactive model particles, smaller than 850 micrometers, made of ZrO were prepared, and the experiments were carried out using vibrating tubes with an outlet diameter from 2 to 4 mm. The outlet diameter significantly affected the flowability measurements. When using the tube with a 4-mm-outlet diameter, the flowability of all the model particles was successfully measured. The inclination angle of the tube, also, affected the flowability measurements. From the advantages of high sensitivity, short measurement time, simple structure, and easy operation, the vibrating tube method is expected to be applied to the remote flowability measurement of the MOX particles.

Particle flowability test using a vibrating tube with a tapered end was carried out to evaluate the applicability of this method to the analysis of MOX particles for nuclear fuel pellet fabrication. In this experiment, zirconia particles were used as model particles, which are less than several hundred micrometers in diameter. The sample particles were prepared by mixing the particles with different sizes, whose shape and surface state were changed by a mechanical treatment. The experimental results showed that the removal of smaller particles is more effective than the mechanical surface treatment to improve the flowability. Furthermore, it was found that the vibrating tube method can identify the difference of the particle flowability more easily and clearly than the method based on Carr's flowability index.

The applicability of the vibrating tube method to the analysis of the flowability of the MOX (mixed oxide of PuO and UO) particles for nuclear fuel pellet fabrication has been studied experimentally. As model particles, five different size of ZrO irregular particles smaller than 850 micro meters were used. It was found that the flowability measurement is possible using a suitable vibrating tube. The critical vibration acceleration making particle flow, which is a factor for evaluating the flowability, has correlation with the Carr's flowability index. From the advantages of high sensitivity, short measurement time, simple structure and simple operation, the vibrating tube method is expected to be applicable to a remote analysis for the flowability of MOX particles.

JAEA is developing simplified pelletizing MOX fuel fabrication process for fast breeder reactor. The final product of de-nitration, conversion and granulation process, are MOX fuel particles, of which diameter is hundres micrometer. These particles should have high flowability for easy handling in next process. The powder flowability is now evaluated by Carr's flowability index. In this oral presentation, the feasibility of powder flowability evaluation using vibrationg capillary method is investigated, employing ZrO particles of shich parameters are diameter and particle shape (shapes are varied by gronding particle edge). Screening small particles under about 100 micrometer contribute best the improvement of powder flowability, screening small particle under 50 micrometer in the second, and rounding particle shape in the third.

The flowability of model particles has been investigated using the vibrating tube method, to evaluate the applicability of this method to MOX (mixed oxide of PuO and UO) particles, which are nuclear fuel for fast reactors (FRs). In this experiment, pulverized ZrO particles and granulated WO particles of 106-250 micrometers in particle diameter were used as the model particles. The amplitude of vibration was increased to a maximum value and then decreased to zero, and the mass of particles discharged from the vibrating tube was measured at constant time intervals. From the experimental data, flowability profiles, i.e. the relationships between the mass flow rate and vibration acceleration were obtained. It was found that for the ZrO samples, the effect of the concentration of fine particles on the flowability was evaluated by the two factors; while for the WO samples, the flowability was evaluated only by the characteristic mass flow rate.
