Abstract
The Fukushima Daiichi accident in 2011 exposed how zirconium alloy clad fuel can oxidize rapidly at high temperatures and react violently with coolant, producing hydrogen and ultimately leading to hydrogen explosions. This event spurred the development of Accident Tolerant Fuel (ATF) for Light Water Reactors (LWRs). Iron based alloys (e.g., FeCrAl, APMT™, 310SS, 304SS) offer...

The Near Surface Disposal (NSD) facility which designed by the Center for Radioactive Waste Technology (CRWT) needs to be evaluated from the possibility of radionuclide release from the facility to ensure its radiation safety to human and environment. Cesium-137 was chosen as the radionuclide of concern due to its high mobility in environment, long half-life, and total activity in waste...

As shown in Fukushima Daiichi accidents, radioactivity absorption in water ponds (pool scrubbing) is highly efficient in mitigating Source Term to the environment during Severe Accidents (SA). Therefore, SA analytical tools should include an accurate modelling that provides reliable insights into pool scrubbing effects and reduces the overall uncertainties in fission products released to the...

The application of advanced fluids with improved thermal properties is a potential approach to enhance heat transfer efficiency in nuclear reactors, resulting in an elevation in the safety margin. This study investigates the impact of a hybrid TiO₂-Cu/water nanofluid on the thermodynamic behavior of coolant flow within a triangular array of a PWR subchannel. A single-phase flow of a...

In light of the escalating climate crisis, the global dependence on fossil, non-renewable, and polluting energy sources presents a significant challenge to mitigating the adverse environmental and climatic effects resulting from the unchecked use of such sources. In this context, nuclear energy emerges as a clean and environmentally friendly alternative, with the potential to meet the growing...

This study investigates the feasibility of Boron Neutron Capture Synovectomy (BNCS) as a targeted treatment for rheumatoid arthritis using accelerator-based neutron sources. BNCS offers a non-invasive alternative to surgery by delivering high-linear energy transfer (LET) radiation directly to diseased synovial tissue through the 10B(n,α)7Li reaction. A compact epithermal neutron beam was...

The Kingdom of Morocco has a 2 MW research reactor (TRIGA MARK II) and an interim storage facility at the Maamoura Nuclear Research Center (CENM), managed by the Nation-al Center for Nuclear Energy, Science, and Technology (CNESTEN), designed for radioac-tive waste management and treatment on a national scale. Spent radioactive resins (SRR) are commonly used to clean and treat water pool...

Abstract
Flow pulsations in tightly spaced fuel rod bundles are an important phenomenon in reactor thermal-hydraulics, as they can cause vibrations that may compromise structural integrity. These pulsations, originating from coherent gap vortex streets between fuel rods, can induce vibrations and fatigue in reactor components. In this work, we investigate this behavior using Computational...

At King Fahd University of Petroleum and Minerals (KFUPM), the radiological safety of a proposed shallow-land repository—projected to be reinforced-concrete vaults measuring 24 m × 18 m × 9 m for low- and intermediate-level radioactive waste (LILW)—was evaluated with the RESRAD-OFFSITE v4.0 code alongside specific hydrogeological, geochemical, and lifestyle information. The inventory was...

Monte Carlo methods have become indispensable tools in the analysis and safety assessment of nuclear power plants and nuclear facilities. Their ability to model complex particle transport processes with high spatial and energy resolution enables advanced applications across reactor neutronics, inventory and activation analysis, radiation protection, reactor safety and environmental monitoring....

The effects of helium ion (He+2) implantation into glassy carbon (GC) were systematically investigated. He+2 ions with an energy range of 17 keV were implanted into GC to fluences of 10¹⁶, 10¹⁷, and 10¹⁸ cm-² at room temperature (RT). The as-implanted GC samples were subsequently vacuum annealed at 300 °c, 500  °c, and 800  °c for 1 hour. The structural evolution of GC was characterized using...

I. Introduction
The goal of this work is to improve the understanding of gas build-up mechanisms and support the design of safer containment and transport systems in nuclear environments. In particular, the focus is on hydrogen accumulation, which poses a significant risk due to its flammability and potential for explosion. Developing and validating accurate predictive models is essential for...

Abstract

This research focuses on the design and analysis of a High-Temperature Gas-Cooled Reactor (HTGR), specifically utilizing the High Temperature Test Reactor (HTTR) model, with the objective of achieving an outlet temperature of 850 °C and a thermal power output of at least 70 MWth without altering the core volume. The study meticulously addresses critical safety aspects, emphasizing...

New types of nuclear reactors are pushing the limits of what fuels need to deliver in terms of safety, efficiency, and long-term performance. This report looks closely at two important fuels that are leading the way: High-Assay Low-Enriched Uranium (HALEU) and Tristructural-Isotropic (TRISO) fuel. HALEU, with uranium-235 enrichment levels between 5% and 20%, makes it possible to build smaller,...

I. Introduction
Nuclear waste generates hydrogen at a slow rate via various mechanisms and this hydrogen must be released in a safe manner. In some instances, the hydrogen is released in discrete “burps” rather than as a continuous release. Ignition from these releases has the potential to injure people nearby. The goal of this work is to improve the understanding of overpressure development...

The tin-tailing processing industry in Malaysia has long operated with minimal regulatory oversight, particularly regarding radiological safety and environmental management. This has resulted in significant exposure risks to workers and surrounding ecosystems due to elevated level of Naturally Occurring Radioactive Materials (NORM) and heavy metals. Radiological Impact Assessment (RIA)...
