Available in PDF, EPUB and Kindle. Book excerpt: A study was made of the phase relations and the properties of uranium-fissium alloys which have compositions bracketing that intended for the first core loading of Experimental Breeder Reactor II. The fissium aggregate in the alloys consisted of the elements Zr, Nb, Mo, Ru, Rh, and Pd. Phase relations are shown to parallel closely those in the dominant U--Mo--Ru ternary system. The uranium gamma phase is stabilized down to 552 deg C, while the beta phase is entirely suppressed at high fissium contents. Certain crystallographic data are given and the minor phases that occur in the alloys are identified. In cast and gamma-quenched alloys the retention of the high-temperature gamma phase produced low hardness and low density. The thermal expansion behavior of the alloys is shown to be dependent upon composition and prior thermal history. Thermal conductivity data are presented for uranium and the uranium-fission alloys. The thermal conductivities of the alloys decrease with increasing fissium concentration.

Available in PDF, EPUB and Kindle. Book excerpt: The Metallurgy of Nuclear Fuel: Properties and Principles of the Technology of Uranium, Thorium and Plutonium is a systematic analysis of the metallurgy of nuclear fuel, with emphasis on the physical, mechanical, and chemical properties as well as the technology of uranium, thorium, and plutonium, together with their alloys and compounds. The minerals and raw material sources of nuclear fuel are discussed, along with the principles of the technology of the raw material processing and the production of the principal compounds, and of the pure metals and alloys. Comprised of three parts, this volume begins with an introduction to the history of the discovery of uranium and its position in the periodic system; its use as a nuclear fuel; radioactivity and isotopic composition; alloys and compounds; and physical, mechanical, and chemical properties. The effect of mechanical and thermal treatment, thermal cycling and irradiation on the physicochemical properties of uranium is also examined. The next two sections are devoted to thorium and plutonium and includes chapters dealing with their uses, alloys and compounds, and methods of recovery and purification. This book is written for university students, but should also prove useful to young production engineers and scientific workers who are concerned with problems in the metallurgy of nuclear fuel.
Download or read book Development and Properties of Uranium base Alloys Corrosion Resistant in High Temperature Water written by I. Cohen and published by . This book was released on 1955 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of pile irradiations on the physical properties and corrosion resistance of U-- Mo, U-- Nb; and U--Si alloys are reported. The dimensional stability under irradiation of the gamma phase U-- Mo and U-- Nb alloys is excellent; however, an isotropic volume increase of 4 to 6% per wt.% burnup may limit the ultimate fuel element life. Corrosion resistance of the gamma-phase alloys appesrs to be improved when subjected to s neutron field; this is attributed to an irrsdiation induced stabilization of the gamma phases. The U/ sub 3/Si alloy, on the other hand, suffered severe deterioration, particularly of corrosion resistance. Changes in electrical resistivity, hardness, mechanical properties, and crystal structure are presented and the mechanisms producing the observed changes discussed.

Available in PDF, EPUB and Kindle. Book excerpt: Physics and Technology of Nuclear Materials presents basic information regarding the structure, properties, processing methods, and response to irradiation of the key materials that fission and fusion nuclear reactors have to rely upon. Organized into 12 chapters, this book begins with selectively several fundamentals of nuclear physics. Subsequent chapters focus on the nuclear materials science; nuclear fuel; structural materials; moderator materials employed to ""slow down"" fission neutrons; and neutron highly absorbent materials that serve in reactor's power control. Other chapters explore the cooling agents; fluids carrying the energy to its final stage of conversion into electric power; thermal and biological shielding materials; some outstanding reactor components; and irradiated fuel reprocessing. The last two chapters deal with nuclear material quality inspection by destructive and non-destructive methods, and specific materials envisaged for use in future thermonuclear reactors. This monograph will be helpful for a wide range of specialists wishing to gear their research and development, education, and other activities toward the field of nuclear power and nuclear technology.

This book was released on 1962 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The equilibrium microstructures and the kinetics of gamma decomposition of uranium-fissium alloys containing technetium were studied and compared with the characteristics of similar alloys which did not contain technetium. The technetium concentration in the fissium was 12.5 wt% and the uranium-fissium alloys that were examined contained from 3 to 10 wt% fissium. The presence of technetium did not result in the presence of any new phases; it produced only minor changes in the phase relationshipB and in the stability of the gamma- uranium solid solution. Studies of aging behavior and of the structure of slowly cooled alloys indicated that the gamma is slightly more sluggish in its transformation characteristics in the presence of technetium. On this basis, it appears that the property measurements made earlier on uranium --fissium alloys which did not contain technetium can be reliably applied to true fissium alloys. (auth).
