Available in PDF, EPUB and Kindle. Book excerpt: The distortion behavior of graphite as a function of irradiation temperature is reviewed. The behavior of needlecoke and CSF graphite was examined over moderate exposures in the GETR. Results showed needle-coke to be less contracting than CSF. Details of contraction show a minimum contraction rate per 1021 nvt at 600 to 800 deg C for both types. Limitations to be placed on the data presented are listed. (P.C.H.).

Download or read book Radiation Damage in Graphite written by J. H. W. Simmons and published by Elsevier. This book was released on 2013-10-22 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nuclear Energy, Volume 102: Radiation Damage in Graphite provides a general account of the effects of irradiation on graphite. This book presents valuable work on the structure of the defects produced in graphite crystals by irradiation. Organized into eight chapters, this volume begins with an overview of the description of the methods of manufacturing graphite and of its physical properties. This text then presents details of the method of setting up a scale of irradiation dose. Other chapters consider the effect of irradiation at a given temperature on a physical property of graphite. This book discusses as well the changes in dimensions produced by irradiation and the effects of irradiation on the mechanical properties of graphite. The final chapter deals with the accumulation of stored energy, which is one of the main problems caused by the irradiation of graphite in nuclear reactors. This book is a valuable resource for physicists and chemical physicists.

Book excerpt: A high temperature graphite irradiation experinient was performed in the GETR core to determine the effects of differences in manufacturing, formulation, and graphitization temperatures on radiation-induced eontraction. The experiment was performed at temperatures of 800 to 1200 deg C in an intense fast neutron flux. The maximum integrated exposure of the sample positions was 3.2 x 10?sup 21/ nvt, E> 0.18 Mev, corresponding to approximately 24,000 MWD/AT in a conventional graphite-moderated reactor. All the graphites tested, with the exception of the controls, were needle coke filler, coal tar pitch binder graphites varying mn particle size, graphitization temperature, and impregnation. From theoretical and experitnental considerations, the formulations and treatments were expected to result in a relatively stable graphite in the direction transverse to extrusion. For comparison of the experimental results to existing experience, a conventional graphite, CSF, was used at each irradiation position. The results showed that the graphite most stable to contraction was graphaitized at a high temperature(>3100hC) and made from small particle size (all flour) filler. In all cases, the needle coke graphite contracted at a lower rate than the CSF graphite. Differences attributable to the size of extrusion and/or post graphitization cooling rate were discerned readily. Auxil iary to the purposes of the experiment, the apparent thermnal neutron cross section for Co/sup 58/ (plus Co /sup 58m) was determined. Co/sup 58/ and Co/sup 58m/ are the products of the Ni/sup 58/ (n,p) reaction, which is used widely for fast flux monitoring. Both have large thermal neutron capture cross sections which must be accounted for to prevent error in fast neutron dosimetry. In this experiment, a value was determined for the apparent burn-out cross section of 3750 barns. (auth).

Book excerpt: Proceedings of the Fourth Conference on Carbon is a collection of manuscripts presented at the Fourth Conference on Carbon, held at the University of Buffalo on June 15-19, 1959, jointly sponsored by the American Carbon Committee and the University of Buffalo. The contributors explore the manufacture, properties, and use of carbonaceous materials. This book is organized into five parts encompassing 79 chapters. Parts I and II describe the surface and electronic properties, adsorption, and reactivity of carbonaceous materials, including carbon black, activated carbon, coal, and graphite. These parts also cover reactions such as thermal oxidation, gasification, and catalysis. Part III highlights the processes of carbonization, graphitization, and crystallite growth of carbon, while Part IV examines their mechanical and thermal properties. Part V looks into the raw materials used for the manufacture of certain carbon materials and the influence of several properties, including porosity and density. Organic chemists and carbon scientists and researchers will find this book invaluable.
