Abstract: Charge Coupled Devices (CCD) are being used for reactor neutrino experiments and have already demonstrated their potential in constraining new physics models. The prospect of a Skipper-CCD experiment looking fo...

The nuclear industry is a unique sector that is especially vulnerable to delays. A multitude of impactful factors such as the complexity of design, tight on-site schedules, and a logistically sophisticated end-to-end su...

An experimental method used to study U diffusion at infinite dilution in materials is presented in this work. The spectra of a particles emitted by U at different depth in the material, after the diffusion annealing, is ...

This work presents the characterization and contribution of neutron and gamma components to the absorbed dose in a zero power nuclear reactor. A dosimetric method based on Fricke gel was implemented to evaluate the separ...

Este trabajo incluye el análisis de los procesos físicos más importantes que ocurren en la celda de un reactor nuclear y la calificación del programa de celda WIMS, que calcula los parámetros neutrónicos asociados ...

Fil: Jinchuk, Darío. Asociación Argentina de Tecnología Nuclear; Argentina. La empresa INVAP S.E. firmó, en julio de 2000, un contrato por 180 millones de dólares con la Organización Australiana de Ciencia y Tecnol...

O artigo apresenta a situação da produção de energia elétrica no Brasil e expõe os problemas para a implementação de um novo modelo no setor energético e para a inclusão de termelétricas em um grande sistema h...

Abstract Abstract: This article discusses the political dynamic of agenda-setting in the subfield of international nuclear co-operation, within an analytical framework that integrates the literature on international co-...

Modal seismic analysis evaluates the seismic response of nuclear plants by combining dominant vibration modes under a prescribed pseudo-acceleration spectrum. Such analyses typically consider only the thermal and kinemat...

A multi-dimensional computational fluid dynamics (CFD) one-phase model to simulate the incore coolant circuit of a Pressurized Heavy Water Reactor (PHWR) of a nuclear power plant (NPP) was performed. Three-dimensional (3...

Traditional static security assessments difficult to capture the dynamic strategic interactions and behavioral decision-making inherent in extreme nuclear security risks. To address this, we propose a tripartite evolutio...

The paper presents a methodology and an example of determining the floor response spectrum of nuclear power plant building structures under earthquake loads. When critical energy infrastructure facilities are consider...

Thorium and its compounds (carbides and nitrides) are being investigated as possible materials to be used as nuclear fuels for Generation-IV reactors. As a first step in the research of these materials under irradiation,...

We have shown that boron neutron capture therapy (BNCT) could be an alternative for the treatment of poorly differentiated thyroid carcinoma (PDTC). Histone deacetylase inhibitors (HDACI) like sodium butyrate (NaB) cause...

The use of Zn in nuclear reactors reduces the amount of 60Co generated as a consequence of the natural activation of Co. On the other hand, isotopically enriched Zn can be used as a tracer in biological systems. At the p...

137Cs can be an important environmental contaminant due to fallout from nuclear reactor accidents and atomic weapons testing. Its contribution to the air gamma dose rate at 1 m height above contaminated ground depends on...

In this work, we investigated the photocatalytic removal of NOx using 3D-printed supports. Monolithic supports withinternal channels were fabricated by Fused Modelling Deposition (FDM) using PET as the filament feedstock...

Abstract As the first safety barrier of nuclear reactors, zirconium alloy cladding tubes have attracted extensive attention because of its good mechanical properties. The strength and ductility of zirconium alloy are of ...

In this paper it is presented the concept and design of a new type of spacecraft that could be used to make the first manned interstellar travel. Solar one would integrate three near-term technologies, namely: compact nu...
