Initial Safety Parameter Evaluation of a PWR Loaded with Thorium and Reprocessed Fuel

Brazilian Journal of Radiation Sciences
The once-through cycle (OTC) of nuclear fuel results in storing large quantities of high-radioactive isotopes. Alternatively, the closed cycle (CC), which involves reprocessing and reusing spent nuclear fuel, improves fuel utilization and reduces high ...

Multiscale Analysis of Amine‐Containing CO2 Capture Membrane via Dissipative Particle Dynamics Simulations Using Ab Initio Elongation Method‐Based Parameters

Carbon Energy, EarlyView.
Elongation (ELG) method for calculating the electronic structures of aperiodic polymers was combined with dissipative particle dynamics (DPD) simulation to perform more reliable simulations using quantum chemistry (QC)‐based parameters. The method was employed to analyze phase separation in an amine‐containing CO2 capture membrane, and the results ...

Long-Term Use of Nuclear Energy from the Aspect of Economy and Greenhouse Gas Emissions

Energies
Conventional sources of electricity are limited and they pollute the Earth, so it is necessary to think about an additional source of electricity in the future. Nuclear power is one of the options. Two scenarios using different shares of nuclear power in

X‐Ray Absorption Sensitivity at 5d$5d$ Edges of High‐Valent Light Actinides to Crystal‐Field Strength and Covalency Effects

Chemistry – A European Journal, EarlyView.
Analysis of x‐ray absorption spectra of U(VI) and U(V) oxides indicates an important role of U 5f−O$5f-\rm{O}$ 2p$2p$ charge transfer for increasing the 5f$5f$ occupancy and thereby affecting the ground state properties. ABSTRACT The 5f$5f$ states were probed in ThO2$\rm{ThO}_2$ and U(VI) and U(V) oxides using x‐ray absorption spectroscopy at the ...

Thorium fuels for light water reactors - steps towards commercialization [PDF]

, 2015
Thorium-containing nuclear fuel is proposed as a means of gaining a number of benefits in the operation of light water reactors, some related to the nuclear properties of thorium and some related to the material properties of thorium dioxide. This thesis

Methanol With Increased Water Content in Internal Combustion Engines

Chemie Ingenieur Technik, EarlyView.
This study investigates the potential to improve overall Well‐to‐Wheel efficiency by using low‐purity methanol from synthesis of hydrogen and furnace gas as CO2‐source. Combustion efficiency is comparable to pure methanol, while distillation energy could be saved.

Reusing depleted oil and gas wells for geothermal energy: Feasibility, challenges, and a decision‐making framework for sustainable conversion

Deep Underground Science and Engineering, EarlyView.
The graphical abstract presents a structured decision‐support framework for assessing the feasibility of converting depleted oil and gas wells into geothermal energy systems. The left panel illustrates a comprehensive, multi‐stage decision‐making framework progressing from prefeasibility screening and technical–economic analysis to policy alignment ...
