Available in PDF, EPUB and Kindle. Book excerpt: The objective of this task is to evaluate the transition temperature shift of the WF-70 weld material at the beltline and nozzle course locations in the Midland reactor vessel. This material is classified as an LUS weld material, and the fracture toughness is to be characterized in the as-received condition as well as three levels of irradiation fluence, 0.5, 1.0, and 5.0 x 1019 neutrons/cm2. A complete survey of the material chemistries and mechanical properties has been made in the unirradiated condition.
Download or read book J R Curve Characterization of A533 B Weld Metal with Irradiation and Postirradiation Annealing written by FJ. Loss and published by . This book was released on 1981 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: The potential benefit of a cyclic postirradiation annealing and reirradiation procedure is investigated as a means of mitigating the progressive embrittlement with irradiation of commercial reactor vessel steels. Material characterizations include two representative A533-B weld deposits, each containing a high copper impurity level which is associated with a high sensitivity to radiation. Assessments made on the basis of the J-R curve and tearing modulus show that intermediate annealing at 399°C has resulted in a recovery of half of the toughness which was lost with the first irradiation. Subsequent reirradiations, to a total fluence of twice that of the initial irradiation, have resulted in no additional loss in toughness, thereby suggesting a concept of embrittlement arrest associated with the annealing procedure.
Download or read book Irradiation Embrittlement of Reactor Pressure Vessels RPVs in Nuclear Power Plants written by Naoki Soneda and published by Elsevier. This book was released on 2014-09-01 with total page 437 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reactor Pressure Vessels (RPVs) contain the fuel and therefore the reaction at the heart of nuclear power plants. They are a life-determining structural component: if they suffer serious damage, the continued operation of the plant is in jeopardy. This book critically reviews irradiation embrittlement, the main degradation mechanism affecting RPV steels, and mitigation routes for managing the RPV lifetime. Part I reviews RPV design and fabrication in different countries, with an emphasis on the materials required, their important properties, and manufacturing technologies. Part II then considers RVP embrittlement in operational nuclear power plants using different reactors. Chapters are devoted to embrittlement in light-water reactors, including WWER-type reactors and Magnox reactors. Finally, Part III presents techniques for studying embrittlement, including irradiation simulation techniques, microstructural characterisation techniques, and probabilistic fracture mechanics. Irradiation Embrittlement of Reactor Pressure Vessels (RPVs) in Nuclear Power Plants provides a thorough review of an issue that is central to the safety of nuclear power generation. The book includes contributions from an international team of experts, and will be a useful resource for nuclear plant operators and managers, relevant regulatory and safety bodies, nuclear metallurgists and other academics in this field Discusses reactor pressure vessel (RPV) design and the effect irradiation embrittlement can have, the main degradation mechanism affecting RPVs Examines embrittlement processes in RPVs in different reactor types, as well as techniques for studying RPV embrittlement
Download or read book Fracture Toughness Curve Shift in Low Upper shelf Welds series 8 written by and published by . This book was released on 1995 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: This task examines the fracture toughness curve shifts and changes in shape for irradiated welds with low CVN upper-shelf energy (USE). The information developed under this task will augment information obtained from other HSSI tasks performed on two high-USE weldments under the Fifth and Sixth Irradiation Series and on a commercial, low USE under the Tenth Irradiation Series. The results will provide an expanded basis for accounting for irradiation-induced embrittlement in RPV materials. Three low-USE welds have been ordered from ABB-Combustion Engineering (ABB-CE), Chattanooga, Tennessee, and two of them have been delivered to ORNL. ABB-CE fabricated the welds for the Fifth and Sixth Series. Preliminary results of mechanical and chemical tests from these two welds are presented below. The Linde 80 flux was used for all three welds. One weld, Weld 1, was made with the 73W weld wire. Weld wire 73W had copper added to the melt to reduce the variations that are associated with copper-coated weld wire. The other two welds were fabricated with a commercially available copper-coated weld wire, L-TEC 44 heat 44112. One of these two welds, Weld 2, has a target copper level of 0.31 %. This copper level could not be attained using the copper-coated wire, and the coating will be stripped from the wire, which contains 0.07 % Cu. To attain the target copper level, supplemental copper will be added to the weld puddle using an ABB-CE proprietary process. This will slightly delay the delivery of weld 2, the expected delivery date is now the end of April 1995. Weld 3 was fabricated with the same heat of the L-TEC 44 copper-coated weld wire as weld 2, but with supplemental copper added to the weld puddle, which resulted in a weldment containing an average of 0.424 % Cu. The semiannual report for October 1993 through March 1994 discusses the reasons for the above choices of copper content and welding wire.
