Multi‐Objective Energy Management for an Integrated Energy System With Small Modular Reactors Considering Uncertainty

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
An integrated energy system (IES) can alleviate energy crises, promote multi‐energy complementarity, and enhance finer‐grained energy development. Nuclear power is clean and efficient, mainly when using small modular reactors (SMRs), which increase power generation, improve system flexibility, and promote a low‐carbon economy.

Development of an Analytic Nodal Diffusion Solver in Multigroups for 3D Reactor Cores with Rectangular or Hexagonal Assemblies. [PDF]

, 2009
More accurate modelling of physical phenomena involved in present and future nuclear reactors requires a multi-scale and multi-physics approach. This challenge can be accomplished by the coupling of best-estimate core-physics, thermal-hydraulics and ...

A Data‐Driven Hybrid Uranium–Thorium Index for Revealing Nonlinear Nuclear–Gas Substitution Dynamics in Emerging Energy Systems

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
Rapid electricity demand growth and high natural gas (NG) dependence challenge the integration of firm low‐carbon energy systems in emerging economies. This study introduces a hybrid uranium–thorium production index (UTPI) to quantify nuclear energy’s system‐level contribution relative to total final energy demand (TFED), using Türkiye as a ...

Hydrogen Mixing Analyses for a VVER Containment [PDF]

10th International Conference on Nuclear Engineering, Volume 2, 2002
Hydrogen combustion may represent a threat to containment integrity in a VVER-440/213 plant owing to the combination of high pressure and high temperature. A study has been carried out using the GASFLOW 2.1 three-dimensional CFD code to evaluate the hydrogen distribution in the containment during a beyond design basis accident.

Transmuting the Arid: Fission‐Powered Visions—Unlocking Ghana’s Aquatic Destiny Through Nuclear Desalination

Science and Technology of Nuclear Installations, Volume 2026, Issue 1, 2026.
Water scarcity poses a mounting constraint on Ghana’s socioeconomic development, intensified by climate‐driven hydrological variability, rapid urbanization, and industrial expansion. This study presents a Ghana‐specific techno‐economic and policy‐integrated assessment of nuclear‐powered seawater desalination, moving beyond generic applications of ...

Global Fossil Methane Emissions Constrained by Multi‐Isotopic Atmospheric Methane Histories

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 5, 16 March 2025.
Abstract The global CH4 budget of sources and sinks is highly uncertain, particularly the emissions from specific sources such as fossil fuels (FF) or agriculture. Here, we estimate plausible global CH4 source and sink scenarios using historical observations and simulations of atmospheric CH4 mole fraction and its stable isotopic (δ13C‐CH4, δD‐CH4) and
