Review ArticleOpen accessPhrase in the titleNuclear Reactors, their Types and Impact on Safety, Environment and Sustainability towards a Green FutureAyush Kumar A, Godwin Glivin, N. Kalaiselvan, V. MariappanThe current world is shifting rapidly towards clean energy sources due to the rapid depletion of fossil fuels. Also, as a solution to the extremely intense growing demand of energy across most of the countries and increasing pollution, nuclear energy is considered as a strategic alternative as it is both clean and does not pollute the environment. When compared with … …Energy Research Journal, Vol. 11, Issue 1 · 29 Oct 2020 · 6,969 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleTHORIA EHANCEMENT OF NUCLEAR REACTOR SAFETYBarbara Szpunar, Jerzy SzpunarThe recent nuclear accident in Fukushima demonstrates that a nuclear mishap should be viewed using interdisciplinary tools. For example, the urania fuel melts not only because of enhanced neutron flux but also because its thermal conductivity degrades when it oxidizes. Here we present the application of first principles calculations to evaluate the structural, mechanical and thermal properties of traditional urania … …Physics International, Vol. 4, Issue 2 · 20 Dec 2013 · 7,632 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleMathematical Model Predicting the Critical Heat Flux of Nuclear ReactorsChien-Hsiung Lee, Lih-Wu Hourng, Kuo-Wei LinBoiling heat transfer system keeps a nuclear power plant safe without getting over-heated. Crisis will occur if the dissipated heat flux exceeds the critical heat flux value. This study assumes the flow boiling system at high heat flux is characterized by the existence of a very thin liquid layer, known as the &#34sublayer&#34, which is trapped between the heated surface … …Journal of Computer Science, Vol. 8, Issue 12 · 12 Dec 2012 · 7,695 accessesView PDFCite
Research ArticleOpen accessIn the keywordsGraph Representation for Secondary System of Pressurized Water Reactor with Autocatalytic Set ApproachAzmirul Ashaari, Tahir Ahmad, Mustaffa Shamsuddin et al.The pace of nuclear reactor development in increasing and this is caused by the high authoritative ordinance of electricity from the end users. Furthermore, maintaining and controlling nuclear reactor operation are high priorities due to safety reasons. The aim of this paper is to describe the secondary system of Pressurized Water Reactor (PWR) system by using graph. Furthermore, fuzzy graph … …Journal of Mathematics and Statistics, Vol. 11, Issue 4 · 30 Dec 2015 · 7,062 accessesView PDFCite
Research ArticleOpen accessIn the abstractThermal Hydraulic Analysis of Double Ended Hot Leg Pipeline Break Accident in AP1000 ReactorM.M. Sadeghiazad, F. Choobdar RahimIn the present research, the Loss of Coolant Accident (LOCA), as a postulated accident in nuclear reactors, in its worst condition called large LOCA has been modeled. A specific type of large LOCA in which a totally guillotine break occurs in the hot leg pipe is the Double Ended Hot Leg (DEHL). Once the ‘LOCA’ occurs, the pipe is break … …Energy Research Journal, Vol. 11, Issue 1 · 14 May 2020 · 7,661 accessesView PDFCite
Research ArticleOpen accessIn the abstractFree Particle Spin SpeedNicolae Petrescu, Florian Ion Tiberiu PetrescuThe electron and the proton are stable particles, compounds of the atoms, which in turn are the macroscopic scale components. A heated metal plate becomes the source of a cloud of electrons, which by an acceleration in an electromagnetic field becomes an electron beam. Protons are obtained by ionized hydrogen atoms; as the mass of the electron is negligibly small … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 3 · 5 Jul 2019 · 7,775 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Proposed Design for Illumination and Cameras Surveillance System for Optimum Supervision at a Perimeter Area of Nuclear FacilityAmir Abdel Wadoud, Alaa Abdelwahab SalehAn important component of a comprehensive security plan is lighting. Security Protective Lighting has three functional objectives: To illuminate a person, object, place or condition of security to permit observation and identification, to be a physical deterrent through the glare effect of direct light on the human eye and to be a psychological deterrent creating in an intruder's mind the … …American Journal of Applied Sciences, Vol. 15, Issue 1 · 3 Feb 2018 · 8,051 accessesView PDFCite
Research ArticleOpen accessIn the abstractSustainable Energy for Aerospace VesselsRelly Victoria Petrescu, Raffaella Aversa, Bilal Akash et al.The advances in solar technology and electric propulsion now offer the promise of new, very capable space transport systems that will allow us to effectively explore the solar system. NASA has developed many concepts of space-powered spacecraft with power levels ranging from tens to hundreds of kilowatts for robotic and asteroid-driven missions and Mars. This paper describes two electrical/chemical propulsion … …Journal of Aircraft and Spacecraft Technology, Vol. 1, Issue 4 · 4 Nov 2017 · 8,009 accessesView PDFCite
Research ArticleOpen accessIn the abstractSome Proposed Solutions to Achieve Nuclear FusionRelly Victoria Virgil Petrescu, Aversa Raffaella, Samuel Kozaitis et al.Despite research carried out around the world since the 1950s, no industrial application of fusion to energy production has yet succeeded, apart from nuclear weapons with the H-bomb, since this application does not aims at containing and controlling the reaction produced. There are, however, some other less mediated uses, such as neutron generators. The fusion of light nuclei releases enormous … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 3 · 20 Jul 2017 · 8,836 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of Power Uprate in Nuclear Power PlantsAlejandro Nuñez-Carrera, Ana Lidia Carreño-Padilla, Erick Gilberto Espinosa-Martínez, Raúl Camargo-CamargoThe three main strategies used by the utilities in order to obtain more benefits from the nuclear installations focused on electricity production and in order to satisfy their demand without carbon dioxide emissions are: (1) Power uprate, (2) plant life management and (3) plant life extension. Alone in the United States, the Nuclear Regulatory Commission has approved more than 140 … …Energy Research Journal, Vol. 8, Issue 1 · 25 Jun 2017 · 7,599 accessesView PDFCite
