Radiation Qualification of Nuclear Reactor Components

Nuclear Technology, 1977
Equipment used in nuclear power reactors requires qualification to environments expected under both postulated accident and aging conditions. Proper simulation of the radiation environments requires a knowledge of the reactor radiation fields as well as an understanding of the physical mechanisms of radiation effects, including dose-rate effects, total

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 ...

A single-component fuel cell reactor

International Journal of Hydrogen Energy, 2011
Abstract We report here a single-component reactor consisting of a mixed ionic and semi-conducting material exhibiting hydrogen-air (oxygen) fuel cell reactions. The new single-component device was compared to a conventional three-component (anode/electrolyte/cathode) fuel cell showing at least as good performance.

Structural integrity of fast reactor components

Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1990
Abstract 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. For example, its high boiling point means that the

Reactor Installations with Sodium-Cooled Fast Reactors for Two-Component Nuclear Energy

Atomic Energy, 2020
The experience of origination and operation of BN-600, -800 and development of BN-1200 commercial power units of two-component nuclear energy are recounted. Substantiation is given for the engineering solutions allowing efficient production of electricity and closure of the nuclear fuel cycle with sodium-cooled fast reactors.

Profiling a reactor component using ultrasonics

1993 IEEE Instrumentation and Measurement Technology Conference, 1995
Nuclear reactors have many components within the reactor vessel. During the life of a reactor it is possible for these components to be displaced or deformed because of the thermal cycles to which they are subject. Also, these components are handled during refuellings and reconfigurations of the core.

In-Reactor Deformation of Zirconium Alloy Components

Journal of ASTM International, 2008
This paper briefly reviews work by the author identifying and describing in-reactor deformation mechanisms of materials and structures used in nuclear reactors, in particular, Zircaloy-2, Zircaloy-4, and Zr-2.5Nb, and the CANDU fuel channel (comprising Zr alloy pressure tubes, calandria tubes, and spacers).

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 ...

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.
