Available in PDF, EPUB and Kindle. Book excerpt: Voids have been produced by 1.2-MeV proton irradiation at 500 degrees C in Type 316 stainless steel contain 2 atomic parts per million (appm) helium. The proton fluence was 6 x 1018 p/cm2. Observation of electron microscope foils, obtained at various positions along the proton pathlength, has shown that the average void diameter increased with increasing number of atom displacements, but that the void density remained constant. Calculated volume swelling ranged from 0.2 to 5%, depending on the number of displacements. In addition to voids, irradiation-produced dislocation loops and small precipitate particles on dislocations have been observed.

This book was released on 1975 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cold-worked Type 316 stainless steel was irradiated at 500and 600°C with 1-MeV protons. The dependence of void formation on displacement damage, irradiation temperature, and microstructure was studied by transmission electron microscopy. Cold working delays the onset of swelling and reduces it, via a reduction in void size, at both irradiation temperatures. Inhomogeneity in the cold-worked microstructure leads to inhomogeneity in the disposition of voids. Swelling at 600°C is greater than at 500°C; the voids are less numerous but larger at the higher temperature. No change in the cold-worked microstructure can be detected by transmission electron microscopy after 500°C irradiation to 23 displacements per atom. Irradiation to a comparable damage level at 600°C results in almost complete elimination of the cold-worked microstructure. Comparison of the results is made with data from reactor irradiation experiments.

This book was released on 1973 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Void formation was studied in annealed Type 316 stainless steel irradiated with 1-MeV protons at 400 C, 500 C, and 600 C (752, 932, and 1112 F) for amounts of damage up to 50 displacements per atom (dpa). Prior to irradiation, the samples were injected with about 5 atomic ppm helium to simulate the fast-reactor situation, where helium is generated by (n,?) reactions. The volume increase at each temperature, as determined by quantitative electron microscopy, varied exponentially with displacement damage and the exponent increased with temperature. Volume increases exceeding 20 percent were associated with 50 dpa at 500 C and 20 dpa at 600 C; no limits on volume increases were apparent at any temperature. Void number density decreased and average void size increased with increasing temperature for a constant damage. A titanium-modified 316 stainless steel developed a very inhomogeneous void distribution when proton irradiated at 600 C. However, the addition of titanium did not appear to diminish the volume increase at damages between 5 and 10 dpa, when compared with ordinary Type 316 stainless steel.

Available in PDF, EPUB and Kindle. Book excerpt: Advances in Nuclear Science and Technology, Volume 7 provides information pertinent to the fundamental aspects of nuclear science and technology. This book discusses the safe and beneficial development of land-based nuclear power plants. Organized into five chapters, this volume begins with an overview of irradiation-induced void swelling in austenitic stainless steels. This text then examines the importance of various transport processes for fission product redistribution, which depends on the diffusion data, the vaporization properties, and the solubility in the fuel matrix. Other chapters consider the integro-differential form of the linear transport equation, which forms the basis for the study of neutron distributions. This book discusses as well the W–H technique and its relevance in transport theory. The final chapter deals with nuclear reactor safety and describes the system in preventing thermal explosions. This book is a valuable resource for thermal reactor physicists, industrial engineers, theoreticians, scientists, and research workers.
