Описание: This thesis investigates the behavior of two candidate materials (a-SiO? and MgO) for applications in fusion (e.g., the International Thermonuclear Experimental Reactor ITER) and Generation IV fission reactors. Both parts of the thesis – the development of the ionoluminescence technique and the study of the ion-irradiation effects on both materials – are highly relevant for the fields of the ion-beam analysis techniques and irradiation damage in materials. The research presented determines the microstructural changes at different length scales in these materials under ion irradiation. In particular, it studies the effect of the irradiation temperature using several advanced characterization techniques. It also provides much-needed insights into the use of these materials at elevated temperatures. Further, it discusses the development of the ion-beam-induced luminescence technique in different research facilities around the globe, a powerful in situ spectroscopic characterization method that until now was little known.

Описание: The growing operational demands in nuclear fuel, such as longer fuel cycles, higher burnups and use of transient regimes, call for more robust fuel designs and more radiation resistant materials. Implementation of new materials and fuel designs that are able to meet these more challenging conditions requires adequate operational feedback and practical verification of models for prediction of fuel behaviour. This CD-ROM publication presents the proceedings of a technical meeting jointly held by the IAEA and the HOTLAB association of hot laboratories with the aim of providing an overview of the current status, problems and perspectives of post-irradiation examination. The publication consists of the presentations, session summaries and conclusions of the meeting.

Описание: This thesis focuses on the nanomanufacturing of graphene—a newly discovered, two-dimensional material with extraordinary properties—in order to realize its numerous potential applications. Combining experimental implementation with theoretical modelling, it investigates three classes of graphene nanostructure fabrication using particle beam irradiation: (i) doping of graphene using low energy nitrogen irradiation; (ii) joining of graphene sheets with laser and C, N, and Ar ion beam irradiation; and (iii) fabrication of graphene nanopores by means of focused ion beam and electron beam irradiation. The feasibility of the nanomanufacture of graphene using particle beam irradiation is demonstrated by various experimental methods, and the mechanisms involved under different types of beam irradiation are revealed using theoretical calculations. Further, the book analyzes the mechanical and electrical properties of the fabricated graphene nanostructures by means of atomic simulations to predict the application potentials of the proposed methods. The findings help promote the implementation of graphene-structure applications in industry.

Описание: This publication is the outcome of an IAEA coordinated research project on near term and promising long term options for deployment of thorium based nuclear energy. It is based on the compilation and analysis of available results on thorium tristructural isotropic (TRISO) coated particle fuel performance in manufacturing during irradiation and accident condition heating tests. As a result, the project participants concluded that the performance statistics for the high enriched thoria urania TRISO fuel system are in perfect concert with those state of the art requirements for present day high temperature reactor concepts.

Описание: Abstract:

Using Compton scattered gamma-rays to measure local void fraction was first suggested by Kondic and Hahn in 1970. The Compton scattered gamma-ray densitometers they suggested employ a single, narrow beam source and either a well collimated detector or an uncollimated detector. The collimated detector configuration only gives the local void fraction measurement in the small volume where the source and detector collimators intersect. The uncollimated detector configuration is a more efficient design since the local void fraction along the source beam's path is measured in a single reading. A logical extension of the technique is to use wide beam illumination and uncollimated detectors to sample an even greater portion of the flow cross section. This report investigates and demonstrates several methods of inferring two-phase flow parameters using wide beam illumination coupled with two detectors placed symmetrically about he source and pipe. The spatial distribution of the fluid in a slice of the pipe is encoded with respect to energy in the singly scatter photon flux. Two basic techniques are detailed for decoding the spatial information: the method of spectral moments and the method of computed tomography (CT). Examination of the low-order moments of the singly scattered photon spectra from the two detectors provides sufficient information for flow regime identification. Flow asymmetries are revealed by comparison of the spectral moments of the two measured spectra. Further classification of the flow pattern is made on the basis of the first and second moments of the spectra. The real focus of this report is the adaptation and successful demonstration of CT techniques with Compton scattering. Three series expansion techniques are considered: the algebraic reconstruction technique (ART), the simultaneous iterative reconstruction technique (SIRT), and the iterative least squares (ILS) technique. Application of the modified ART, SIRT, and ILS algorithms to a hot-spot and a cold-spot reconstruction problem indicates that SIRT and ILS are more accurate than ART. A more extensive testing of the ILS algorithm for a variety of model flow regimes demonstrates the potential of Compton scatter tomography as a quantitative measurement technique.
