Book excerpt: The investigation of reactor pressure vessel (RPV) material from the decommissioned Greifswald nuclear power plant representing the first generation of Russian-type WWER-440/V-230 reactors offers the opportunity to evaluate the real toughness response. This paper presents test results measured on trepans taken from the multilayer beltline welding seam SN0.1.4 and forged base metal ring 0.3.1 located in the reactor core region of the Unit 4 RPV. This unit was shut down after 11 years of operation. The characterization of the irradiation response was based on the measurement of the hardness, the tensile strength, the master curve reference temperature, T0, and the Charpy-V transition temperature through the thickness of multilayer beltline welding seam SN0.1.4 and the forged base metal ring 0.3.1. For the beltline welding seam we observed a large variation in the through-thickness master curve T0 values. The T0 values measured with the T-S-oriented Charpy size SE(B) specimens strongly depended on the intrinsic welding bead microstructure along the crack tip. The progression of the T0 values through the thickness-forged base metal ring 0.3.1 ranged from 121 to 130C and indicated no irradiation-induced embrittlement within the fluence range of 5.38 to 1.20 1019 n/cm2 (E > 0.5 MeV) through the thickness of the RPV wall. More than the allowed 2 % of the specimen size-adjusted fracture toughness values, KJc-1T, were below the fracture toughness curve for 2 % fracture probability. The reason for the occurrence of very low KJc-1T values was seen in the intergranular planes detected on the fractured surfaces of the specimens. Modified master curve-based evaluation methods indicated the material to be nonhomogeneous. This investigation shows that the measured irradiation response of the investigated RPV materials does not correspond to the forecast according to the current Russian code.

This book was released on 2012-09-22 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Have you ever wondered where the safety factors come from? Why is it that deterministic analysis has reached a very sophisticated level, but in the end empirical factors are still needed? Is there a way to select them, rather than assigning them arbitrarily as is often done? This book clearly shows that safety factors are closely related with the reliability of structures, giving yet another demonstration of Albert Einstein's maxim that "It is incomprehensible that Nature is comprehensible". The book shows that the safety factors are much more comprehensible if they are seen in a probabilistic context. Several definitions of the safety factors are given, analytical results on insightful numbers are presented, nonprobabilistic safety factors are shown, as well as their estimates derived by the inequalities of Bienayme, Markov, Chebushev and Camp-Meidell. A special chapter is devoted to important contributions by Japanese experts. This volume will help to critically re-think the issue of safety factors, which can create a false feeling of security. The deterministic paradigm can be enhanced by incorporating probabilistic concepts wisely where they are needed without treating all variables as probabilistic ones. The book shows that there is a need of their integration rather than separation. This book is intended for engineers, graduate students, lecturers and researchers.

Available in PDF, EPUB and Kindle. Book excerpt: High-performance alloys that can withstand operation in hazardous nuclear environments are critical to presentday in-service reactor support and maintenance and are foundational for reactor concepts of the future. With commercial nuclear energy vendors and operators facing the retirement of staff during the coming decades, much of the scholarly knowledge of nuclear materials pursuant to appropriate, impactful, and safe usage is at risk. Led by the multi-award winning editorial team of G. Robert Odette (UCSB) and Steven J. Zinkle (UTK/ORNL) and with contributions from leaders of each alloy discipline, Structural Alloys for Nuclear Energy Applications aids the next generation of researchers and industry staff developing and maintaining steels, nickel-base alloys, zirconium alloys, and other structural alloys in nuclear energy applications. This authoritative reference is a critical acquisition for institutions and individuals seeking state-of-the-art knowledge aided by the editors’ unique personal insight from decades of frontline research, engineering and management. Focuses on in-service irradiation, thermal, mechanical, and chemical performance capabilities. Covers the use of steels and other structural alloys in current fission technology, leading edge Generation-IV fission reactors, and future fusion power reactors. Provides a critical and comprehensive review of the state-of-the-art experimental knowledge base of reactor materials, for applications ranging from engineering safety and lifetime assessments to supporting the development of advanced computational models.
