This book was released on 1975 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effect of the degree of cold work, as measured by X-ray line broadening techniques, on the irradiation-induced swelling of Type 316 stainless steel has been studied using 5-MeV nickel ions as the bombarding species. The level of cold work is expressed in terms of nonuniform lattice strain, ?. A critical value of ? exists below which swelling is a strongly decreasing function of ?, and above which a saturation of the effect occurs such that further increases in ? have very little influence on the swelling behavior. The critical value of ? increases with increasing temperature and ion dose. The implications of these results on the design of an liquid metal fast breeder reactor fuel rod are discussed.

Available in PDF, EPUB and Kindle. Book excerpt: The effects of some compositional and processing variations on the irradiation-induced swelling of 20 percent cold-worked Type 316 stainless steel have been investigated. Bombardment by 5-MeV nickel ions was used to simulate the fast neutron irradiation which occurs in breeder reactor core components. Swelling in cold-worked Type 316 was found to be lowered by additions of silicon and molybdenum. Swelling was also reduced by increasing the solution-annealing temperature prior to the final cold-working operation.

Download or read book Irradiation Induced Swelling Variations Resulting from Compositional Modifications of Type 316 Stainless Steel written by JF. Bates and published by . This book was released on 1975 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: The irradiation-induced swelling of Type 316 stainless steel has been shown to be strongly dependent upon minor alloying constituents. At fluences around 2 to 4 x 1022 neutrons (n)/cm2 (E > 0.1 MeV) it was shown that increasing the levels of concentration of carbon, phosphorus, and silicon was found to be most effective in increasing the swelling resistance of the alloy system. Manganese concentration was found to exhibit a less pronounced effect on the swelling than those three elemental variations. Variations in sulfur, nitrogen, and boron, to those levels investigated, showed no significant effect on swelling. Molybdenum and colbalt variations resulted in quite anomalous swelling behavior, but the data did suggest that increases in these elements in Type 316 stainless steel would, in some cases, reduce the swelling. Chromium and nickel variations resulted in data which suggested trends but were inconclusive. All of the results indicate a temperature dependence.

Download or read book Effect of Cold Work on Tensile Behavior of Irradiated Type 316 Stainless Steel written by RL. Klueh and published by . This book was released on 1987 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effect of various levels of cold work on the tensile behavior of Type 316 stainless steel was investigated. Tensile specimens were irradiated in the Oak Ridge Research Reactor (ORR) at 250, 290, 450, and 500°C to produce a displacement damage of ~5 displacements per atom (dpa) and 40 atomic ppm He. Irradiation at 250 and 290°C caused an increase in yield stress and ultimate tensile strength and a decrease in ductility relative to unaged and thermally aged controls. The changes were greatest for the 20%-cold-worked steel and lowest for the 50%-cold-worked steel. Irradiation at 450°C caused a slight decrease in strength for all cold-worked conditions relative to the aged material. A large decrease was observed at 500°C, with the largest decrease occurring for the 50%-cold-worked specimen. No bubble, void, or precipitate formation was observed for specimens examined by transmission electron microscopy (TEM). The irradiation hardening was correlated with Frank-loop and "black-dot" damage. A strength decrease at 500°C was correlated with dislocation network recovery. Comparison of tensile and TEM results from ORR-irradiated steel with those from steels irradiated in the High Flux Isotope Reactor and the Experimental Breeder Reactor indicated consistent strength and microstructure changes.

Download or read book The Effect of Low Dose Rate Irradiation on the Swelling of 12 Cold worked 316 Stainless Steel written by and published by . This book was released on 1999 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: In pressurized water reactors (PWRs), stainless steel components are irradiated at temperatures that may reach 400 C due to gamma heating. If large amounts of swelling (>10%) occur in these reactor internals, significant swelling related embrittlement may occur. Although fast reactor studies indicate that swelling should be insignificant at PWR temperatures, the low dose rate conditions experienced by PWR components may possibly lead to significant swelling. To address these issues, JNC and ANL have collaborated to analyze swelling in 316 stainless steel, irradiated in the EBR-II reactor at temperatures from 376-444 C, at dose rates between 4.9 x 10−8 and 5.8 x 10−7 dpa/s, and to doses of 56 dpa. For these irradiation conditions, the swelling decreases markedly at temperatures less than approximately 386 C, with the extrapolated swelling at 100 dpa being around 3%. For temperatures greater than 386 C, the swelling extrapolated to 100 dpa is around 9%. For a factor of two difference in dose rate, no statistically significant effect of dose rate on swelling was seen. For the range of dose rates analyzed, the swelling measurements do not support significant (>10%) swelling of 316 stainless steel in PWRs.
