Austin and published by . This book was released on 1982 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: The work described in this paper is part of a continuing programme to produce well-characterized data for use in the development of models for the prediction of irradiation shift in pressurized water reactor steels. Results are presented for around 50 batches of Charpy specimens, irradiated either in the DIDO or PLUTO heavy water, or in the HERALD light water, research reactors, to doses up to 35 mdpa (?2 x 1019 n/cm2, E > 1MeV). The materials include A533B plate, weld, and heat affected zones. The results are compatible with a log/log relationship between dose and shift with an exponent of 0.5 for all materials. They also show that irradiation response is dependent on heat treatment condition. If it is assumed that the Varsik and Byrne Chemistry Relationship, or a similar expression, is an appropriate parameter to characterize the effect of chemical composition on irradiation sensitivity, the results also demonstrate a difference between plate and weld irradiation sensitivity. An empirical model of the data has been developed and assessed, and this is compared with the Odette physically-based irradiation damage model.

This book was released on 1973 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: About 75 low alloy steels that have been irradiation tested at 450 to 550 F (232 to 288 C) have been chemically analyzed for copper, aluminum, total nitrogen, and combined nitrogen. Uncombined nitrogen content has been found to have a strong modifying action on the effectiveness of copper in controlling sensitivity to irradiation embrittlement at 450 to 550 F (232 to 288 C).

This book was released on 1976 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of weld metal alloying constituents on the irradiation response of reactor vessel weld metal have been evaluated to determine why vessel welds tend to be more sensitive to irradiation damage than parent plate material. Weld data, collected from published reports, were compared on the basis of neutron radiation exposure; subsequent nil-ductility transition temperature (NDTT) shift (measured at the Charpy 30 ft•lb energy fix); chemical composition; postweld heat treatment, and microstructure. The data comparison produced a correlation between NDTT shift with irradiation and a ratio of a weld's major alloying elements. The alloy ratio is designated A/B where the element content of the weld, by weight percent, is expressed: A/B = (Ni + Si)/(Mn + Cr + Mo). As the ratio increases for a weld, higher NDTT shifts with irradiation can be expected. Effects of postweld heat treatment and microstructure are also related to the NDTT shift-A/B correlation. The known effects of copper content on NDTT shift with irradiation have been found to be separate from the effects of the A/B ratio. Both copper and A/B effects, however, contribute to the total NDTT shift experienced by the weld with irradiation.

Download or read book Radiation Damage of Structural Materials written by J. Koutský and published by Elsevier. This book was released on 2013-10-22 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maintaining the integrity of nuclear power plants is critical in the prevention or control of severe accidents. This monograph deals with both basic groups of structural materials used in the design of light-water nuclear reactors, making the primary safety barriers of NPPs. Emphasis is placed on materials used in VVER-type nuclear reactors: Cr-Mo-V and Cr-Ni-Mo-V steel for RPV and Zr-Nb alloys for fuel element cladding. The book is divided into 7 main chapters, with the exception of the opening one and the chapter providing a phenomenological background for the subject of radiation damage. Chapters 3-6 are devoted to RPV steels and chapters 7-9 to zirconium alloys, analysing their radiation damage structure, changes of mechanical properties due to neutron irradiation as well as factors influencing the degree of their performance degradation. The recovery of damaged materials is also discussed. Considerable attention is paid to a comparison of VVER-type and western-type light-water materials. This monograph will be of great value to postgraduate students in nuclear engineering and materials science, and for designers and research workers in nuclear energy.

Download or read book Effect of Irradiation on the Elasto Plastic Toughness of Pressure Vessel Steels written by P. Petrequin and published by . This book was released on 1986 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study on the effect of irradiation on the toughness of pressure vessel materials in the ductile regime has been undertaken. Compact tension (CT) specimens of two pressure vessel steels (A533 B and A508 Class 3) and a weld material of fitting chemical composition were irradiated and received neutron fluences of 3 and 8 x 1019 n/cm2. The J-R curves of these materials were determined between 100 and 290°C. Only a very small influence of irradiation was observed for tests at 290°C. In irradiated condition, the effect of the test temperature is not noticeable. At lower temperature, but in the ductile regime, the weld material appears to be more sensitive to neutron irradiation than the two steels. The forged material exhibited a surprisingly high shift of transition temperature since cleavage rupture occurred up to 100°C.
