Burnup credit reduces the estimated value of $k_{eff}$ in spent fuel criticality safety assessments by accounting for changes in nuclide composition during the burnup process; however, uncertainties in the sample bias of nuclide compositions affect the accuracy of criticality calculation results. To…
As the semiconductor industry advances toward nodes below 7 nanometers, critical dimension small-angle X-ray scattering (CD-SAXS) has become a vital technology for the quantitative measurement of nanoscale deviations. This study investigates the effects of X-ray beam size and photon energy on the pr…
X-ray absorption fine structure (XAFS) is an important structural analysis technique widely used to study the oxidation states, coordination environments, and neighboring atomic characteristics of amorphous materials and disordered systems. However, due to the complexity of XAFS spectra, their inter…
This study aims to investigate the responses of a perovskite-based direct-conversion dual-layer flat-panel detector (DL-FPD) numerically. To this end, the X-ray sensitivity, spatial resolution quantified by the modulation transfer function (MTF), and detective quantum efficiency (DQE) of the DL-FPD …
In high-level radioactive waste geological disposal, bentonite is commonly employed as a buffer/backfill material. The existence form of its colloids in the deep geological repository environment may influence the sorption, diffusion, and migration behaviors of key radionuclides. Focusing on single-…
Self-Powered Neutron Detector (SPND), as an important detection component for in-core neutron fluence rate measurement, exhibits generally small signal currents and delayed response due to its special response mechanism. Currently, research on SPND sensitivity also lacks in-reactor experimental data…
X-ray Absorption Fine Structure (XAFS) is an important structural analysis technique widely applied to investigate the oxidation state, coordination environment, and neighboring atomic properties of amorphous materials and disordered systems. However, due to the complexity of XAFS spectra, their int…
The ultracold neutron (UCN) transport code, MCUCN, designed initially for simulating UCN transportation from a solid deuterium ($\rm SD_{2}$) source and neutron electric dipole moment experiments, could not simulate UCN storage and transportation in a superfluid $\rm{^{4}{He}}$ (SFHe, He II) source …
High multipole electromagnetic transitions are rare in nature. The highest multipole transition observed in atomic nuclei is the electric hexacontatetrapole E6 transition from the T1/2 = 2.54(2)-min Jπ = 19/2− isomer to the 7/2− ground state in 53Fe with an angular momentum change of six units. In t…
The fusion dynamics of \ce{^6Li} and \ce{^7Li} projectiles incident on \ce{^{13}C} and \ce{^{12}C} targets, respectively, near the Coulomb barrier, were investigated theoretically using the antisymmetrized molecular dynamics (AMD) model. Within the AMD framework, the ground state configurations of \…
Nuclear masses play a crucial role in both nuclear physics and astrophysics, driving sustained efforts toward their precise experimental determination and reliable theoretical prediction. In this work, we compile the newly measured masses for 296 nuclides from 40 references published between 2021 an…
Unmanned aerial vehicle (UAV)-borne gamma-ray spectrum surveys play a crucial role in geological mapping, radioactive mineral exploration, and environmental monitoring. However, raw data are often compromised by flight and instrument background noise, as well as detector resolution limitations, whic…
Physics-informed neural networks (PINNs) play a vital role in machine learning and demonstrate significant advantages in addressing complex physical problems. The PINN method enables rapid prediction of 220Rn progeny concentration and holds significant importance for the regulation and measurement o…
In this study, the dosimetric characteristics (thickness applicability, preheating time, temperature and hu midity dependence, in-batch uniformity, readout reproducibility, dose linearity, self-decay, and electron energy response) of engineered polycarbonate films irradiated with an electron beam (0…
Many adsorbents have been developed for uranium recovery to ensure global energy and environmental security. However, most reported adsorbents involve complex preparation process and rely heavily on petrochemical feedstocks, which undoubtedly increases carbon emissions from production in the nuclear…
Computational phantoms play an essential role in radiation dosimetry and health physics. Although mesh-type phantoms offer a high resolution and adjustability, their use in dose calculations is limited by their slow computational speed. Progress in heterogeneous computing has allowed for substantial…
With the significant development of high-intensity hadron (proton and heavy ion) accelerator facilities, the space charge effect has become a major limiting factor for increasing beam intensity because it can drive particle resonance, forming beam halos and causing beam quality degradation or even b…
In this paper, a novel method for investigating the particle-crushing behavior of breeding particles in a fusion blanket is proposed.

Compared with conventional thermal neutron reactors, fast reactors exhibit higher fuel enrichment and a harder neutron spectrum, while the Doppler broadening effect, primarily associated with U-238, is weaker during reactor operation. Consequently, the impact of core structural deformation on reacti…

Doped elements in alloys significantly impact their performance. Conventional methods usually sputter the surface material of the sample, or their performance is limited to the surface of alloys owing to their poor penetration ability.
