Component vibration of VVER-reactors — diagnostics and modelling

Progress in Nuclear Energy, 1995
Abstract Flow induced vibrations of reactor pressure vessel (RPV) internals (control element and core barrel motions) at VVER-440 reactors have lead to the development of dedicated methods for on-line monitoring. These methods need a certain developed stage of the faults to be detected. To achieve a real sensitive early detection of mechanical faults

Reactor Applications of Two-Component Plasmas

IEEE Transactions on Plasma Science, 1976
The physics of two-energy-component toroidal plasmas (TCT) is reviewed. Energy "breakeven" using the TCT mode (deuteron beams on a triton-target plasma) can be attained at much smaller n? and temperature than in thermal plasma operation. This result reflects the fact that the fusion power density in a TCT can be much larger than in a thermal DT plasma ...

Structural integrity of fast reactor components

Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1990
The paper focuses on the generic aspects of the main structural integrity issues in the liquid-sodium-cooled fast reactor. The choice of sodium as a coolant has important consequences for the deformation and failure process in the materials used for the main plant components.

Using fast reactor component evaluation for pressurized water reactor life extension

JOM, 1999
An understanding of the effects of long-term, low-dose-rate radiation on core components is critical to light-water reactor plant life extension. Following reactor shutdown, materials that had experienced long exposures to low-dose-rate irradiation were retrieved from the EBR-II research reactor for analysis.

Development and testing of AZEP reactor components

International Journal of Greenhouse Gas Control, 2007
Abstract The advanced zero emissions power plant (AZEP) project addresses the development of a novel “zero emissions,” gas turbine-based, power generation process to reduce local and global CO 2 emissions in a cost-effective way. The key element in AZEP is an integrated MCM-reactor, in which (a) O 2 is separated from air by means of a mixed ...

Nondestructive testing of nuclear reactor components

Nuclear Engineering and Design, 1965
Abstract This paper summarizes some of the significant research and development efforts in nondestructive testing of nuclear reactor components done by various U.S. Atomic Energy Commission agencies and contractors since 1958. The methods of nondestructive testing discussed here include fuel assay, thermal testing, penetrating radiation (X-rays ...

A review of flow-induced vibrations in reactors and reactor components

Nuclear Engineering and Design, 1983
Abstract This paper presents a review of the state of the art of two classes of vibration problems encountered in reactors and reactor peripherals: namely, vibration of cylindrical structures induced by cross flow and by axial flow. A historical perspective is given first, in which the milestone contributions that have advanced the state of the art ...

Power-producing fusion reactor using presently available components

The 30th International Conference on Plasma Science, 2003. ICOPS 2003. IEEE Conference Record - Abstracts., 2003
Summary form only given, as follows. The problem with fusion reactors today is that they do not produce appreciably more power than they consume to maintain the plasma. However, this problem may be solved by considering the total fusion cycle. In the present concept, deuterium is fused with tritium to create about 17 MeV of energy per fusion.

Component Event Data Bank Fast Breeder Reactors

1986
Fast Breeder Reactors (FBR) are acquiring more and more importance in the European nuclear programme, mainly thanks to the contributions of French plants, as Rapsodie, Phenix and Superphenix. Italy is directly interested in developing such a field, by building up an experimental reactor, whose aim will be the testing of new fuel elements (P.E.C.
