Book Preparation and examination of zircaloy 2 strip material and calandria tubing to be used in irradiation growth experiments in the atr reactor at idaho falls

Download or read book Preparation and examination of zircaloy 2 strip material and calandria tubing to be used in irradiation growth experiments in the atr reactor at idaho falls written by R. M. Condie and published by . This book was released on 1983 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The microstructures of production calandria tubes have been evaluated. specimens from these tubes are being irradiated in the advanced test reactor (atr) at idaho falls to study irradiation growth. a series of strip materials with controlled microstructures has been successfully prepared from common starting material. the grain sizes and dislocation densities span those available in production calandria tubes. specimens from these materials being irradiated in atr will reveal the effect of microstructure on irradiation growth.

Book Procedures for measuring zircaloy 2 growth specimens prior to and following irradiation in the atr reactor at idaho falls including initial results

Download or read book Procedures for measuring zircaloy 2 growth specimens prior to and following irradiation in the atr reactor at idaho falls including initial results written by R. W. Gilbert and published by . This book was released on 1985 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Growth specimens made from zircaloy-2 calandria tube materials are being irradiated in the advanced test reactor at idaho falls. the sampling and measurement procedures used during the experiment are described and preliminary data are presented. the requirement of measuring specimen lengths to +- 0.5 mu m has been met. initial results are contrary to expectations and may reflect a transient behaviour caused by relaxation of micro-stresses within the specimens.

Book Irradiation growth of zircaloy 2 at 330 k results of measurements after the second and third irradiation in the atr reactor at idaho falls

Download or read book Irradiation growth of zircaloy 2 at 330 k results of measurements after the second and third irradiation in the atr reactor at idaho falls written by M. A. Miller and published by . This book was released on 1985 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes the irradiation growth measurements on zircaloy-2 specimens after second and third irradiations in the advanced test reactor at idaho falls as part of a candev work package to investigate the dimensional stability of calandria tube materials. some specimens have reached fluences of 1 x 10 sup(26) n.m sup(-2), e greater than 1 mev, corresponding to the fluence of pickering calandria tubes after 30 years of operation. the results exhibit large variability in growth behaviour between calandria tube materials from different reactors. most specimens have not yet attained steady state growth rates even at higher fluences.

Book High Temperature Irradiation Growth in Zircaloy

Download or read book High Temperature Irradiation Growth in Zircaloy written by RB. Adamson and published by . This book was released on 1982 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: Irradiation growth behavior of Zircaloy-2 and -4 was studied on specimens irradiated in the Experimental Breeder Reactor II to fluences of 1.4 to 6.3 x 1025 neutrons (n).m-2 (E > 1 MeV) in the temperature range 644 to 723 K. Measurements in the three principal directions on annealed and cold-worked/stress-relieved Zircaloy-2 slab materials provided evidence that growth is a constant-volume process up to about 680 K. The growth strains were shown to be determined by the crystallographic texture, that is, proportional to (1-3(1-3fdc)), where), where fdc is the fraction of basal poles, is the fraction of basal poles, fc, in the direction d. The growth strains for annealed and cold-worked Zircaloy were large relative to previously reported data, were similar in magnitude, were strongly dependent on irradiation temperature, and varied linearly with fluence over the range investigated. Transmission electron microscopy on annealed Zircaloy-4 specimens revealed a few small voids and larger cavities, a grain boundary second phase, and dislocation loops, tangles, and arrays. The high growth strains in annealed Zircaloy appear to be governed by dislocation arrays formed during irradiation. This implies a change in growth mechanism from that pertaining at lower temperatures in annealed material. The data suggest a transition from saturating steady-state growth at lower temperatures to increasing and eventually high steady-state rates under the conditions of these tests.

Book Irradiation Growth of Zirconium Alloys

Download or read book Irradiation Growth of Zirconium Alloys written by JY. Ren and published by . This book was released on 1994 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimental investigation of irradiation growth on annealed Zircaloy-4 and 20% to 50% cold-worked Zr-2.5wt%Nb specimens with stress relief has been carried out. The specimens are irradiated in a heavy water reactor at 610 K to 4.2 x 1024 n/m2 (E > 1.0 MeV). The growth strains increase linearly with fluence. The saturation of growth is not observed for all specimens. The difference of growth behavior between two kinds of Zircaloy-4 tube may be associated with the content of minor alloying elements and impurities that influence the microstructure evolution under irradiation.
