Seismic Response of Reactor Vessel Internals in the IRIS Reactor
Volume 3: Structural Integrity; Nuclear Engineering Advances; Next Generation Systems; Near Term Deployment and Promotion of Nuclear Energy, 2006The intent of this paper is the presentation and discussion of a methodology for the evaluation and analysis of seismic loads effects on a nuclear power plant. To help in focussing the presented methodology, a preliminary simplified analysis of an integral, medium size next generation PWR reactor structure (IRIS project, an integral configuration PWR ...

A High Temperature Gas-Cooled Reactor (HTGR) is particularly attractive due to its capability of producing high-temperature helium-gas and its possibility to exploit inherent safety characteristic. To achieve high temperature helium-gas, reactor internals are made of graphite and heat resistant materials, its surroundings are composed of metals.

An internally illuminated monolith reactor: Pros and cons relative to a slurry reactor
Catalysis Today, 2009In the present study, kinetic models for the photo-oxidation of cyclohexane in two different photoreactor systems are discussed: a top illumination reactor (TIR) representative of a slurry reactor, and the so-called internally illuminated monolith reactor (IIMR) representing a reactor containing immobilized catalyst.

International Thermonuclear Experimental Reactor
IECEC 96. Proceedings of the 31st Intersociety Energy Conversion Engineering Conference, 2002The development of fusion energy involves significant technical challenges and risks but the potential benefit is huge. International collaboration, which makes the best use of worldwide expertise and ideas while sharing the cost, is the best way to develop fusion energy.

Hydroprocessing Reactor Internals
2017As discussed in other chapters, catalytic hydrotreating upgrades petroleum fractions by saturating olefins and aromatics with hydrogen, and by converting contaminants such as sulfur, nitrogen and sometimes oxygen into H2S, NH3, and H2O respectively. Hydrotreating also remove trace elements such as Ni, V, Fe, Si, As and Hg.

International Thermonuclear Experimental Reactor (ITER)
Revue Générale Nucléaire, 1989A new international cooperation for the next step in the tokamak development will start in the spring 1988 by the four partners, EURATOM, Japan, USSR, and USA, under the auspices of the IAEA. The project is referred to as ITER, the acronym for International Thermonuclear Experimental Reactor, and has the goal of producing a conceptual design of the ...

The International Thermonuclear Experimental Reactor
2021The Internal Thermonuclear Experimental Reactor (ITER) is supposed to be the next crucial step on the way (iter) to commercial energy generation by nuclear fusion. It is more a political technological project than a scientific technological one. Born in the twilight years of the Soviet Union, it became caught up in detente politics between East and ...

Effect of Internal Filtration on Slurry Reactor Performance
Industrial & Engineering Chemistry Research, 1998In slurry bubble column reactors, generally small particles (<200 μm) are applied. These particles often introduce a strenuous liquid−solid separation in processes involving liquid-phase products. This operation can be facilitated by performing filtration inside the reactor and thereby utilizing the turbulence induced by rising gas bubbles to keep ...

International Tokamak Reactor (INTOR)
Fusion Technology, 1986The current INTOR design concept and the ongoing work in the INTOR Workshop are reviewed. The ongoing work includes evaluation of innovations that could substantially improve tokamak reactors, analysis of critical technical issues that affect the feasibility of the INTOR design concept and revision of the INTOR conceptual design.
