Energy partitioning for “fuzzy” atoms [PDF]

open access: yesThe Journal of Chemical Physics, 2004
The total energy of a molecule is presented as a sum of one- and two-atomic energy components in terms of “fuzzy” atoms, i.e., such divisions of the three-dimensional physical space into atomic regions in which the regions assigned to the individual atoms have no sharp boundaries but exhibit a continuous transition from one to another.

Progress in Chlorination and Dissolution Technology of Oxides of Uranium and Plutonium

open access: yesHe huaxue yu fangshe huaxue, 2022
The dissolution process of oxides is a key step in the pyrochemical process of spent oxide fuel by electrolyzing in molten salt. The dissolved products will provide feeds for subsequent separation and recovery of U and Pu.

Sudden To Adiabatic Transition in Beta Decay [PDF]

open access: yes, 1998
We discuss effects in beta decays at very low beta energies, of the order of the kinetic energies of atomic electrons. As the beta energy is lowered the atomic response changes from sudden to adiabatic.

Astrophysical SE2 factor of the 12C(α, γ)16O reaction through the 12C(11B, 7Li)16O transfer reaction

open access: yesEPJ Web of Conferences, 2016
The 12C(α, γ)16O reaction plays a key role in the evolution of stars with masses of M > 0.55 M⊙. At the Gamow peak (Ec.m. = 300 ke V, T9 = 0.2), the cross section of the 12C(α, γ)16O reaction is so small (about 10−17 barn) that the direct measurement in ...

Evaluation of important phenomena through the PIRT process for a sodium fire event

open access: yesNihon Kikai Gakkai ronbunshu, 2020
Sodium fire is one of key issues in sodium-cooled fast reactor (SFR) plants. JAEA has developed sodium fire analysis codes, a zone model code SPHINCS and a field model code AQUA-SF, to evaluate the consequence of sodium fire events.

Extraction of Uranium From Alkali Residue With Supercritical Carbon Dioxide Fluid

open access: yesHe huaxue yu fangshe huaxue, 2023
Alkali residue was dissolved by the ammonium hydrogen fluoride method, in which the uranium content is determined to be (16.7±0.3)%(n=6) by inductively coupled plasma optical emission spectrometry(ICP-AES).

Crystallization of Simulated High-Level Nuclear Waste Glasses Under Heat Treatment and Its Impacts on Glass Durability

open access: yesHe huaxue yu fangshe huaxue, 2023
Vitrification is currently the primary choice worldwide for high-level nuclear waste immobilization. This study investigated the crystallization behaviors of glasses containing 24%(mass fraction) and 30% simulated high-level nuclear waste, respectively ...

$3d$-electrons contribution to cohesive energy of $3d$-metals [PDF]

open access: yes, 2018
In this paper a model for $3d$-subsystem of transition $3d$-metals has been proposed and used for calculation of the cohesive energy dependent on $3d$-band filling of particular metal, its bandwidth and effective intra-atomic interaction value.
