By: Dick Mattson and Minghao Qin A U.S. BWR utility contracted with Structural Integrity (SI) to review their current reinspection guidance documents relative to those contained in the BWRVIP inspection guidelines, the purpose of which was two-fold: Are current reinspection guidelines compliant with industry requirements? Are there components where reinspection intervals could possibly be extended? […]
By: Mark Jaeger and Andrew Crompton Acoustic resonance is a phenomenon in which an acoustic system amplifies sound waves whose frequency matches one of its own natural frequencies of vibration (its resonance frequencies). in everyday life. In the most simple at home example, blowing air over the open end of a bottle. Blow too hard, […]
By: Erica Libra-Sharkey INDUSTRY CHALLENGE From the US Department of Energy, Office of Nuclear Energy, “The demanding environments of an operating nuclear reactor may impact the ability of a broad range of materials to perform their intended function over extended service periods. Routine surveillance and repair/replacement activities can mitigate the impact of this degradation; however, […]
By: Bill Weitze 100% of thermal stress was treated as nonlinear gradient stress and linear bending stress was about 12% of the moment stress. Structural Integrity’s (SI’s) review of the stress terms used in piping analysis show that pressure stress does create bending stress in components… EPRI Report 3002014121 “Development of Fatigue Usage Life and […]
By: Scott Chesworth, Bob Grizzi, and Dilip Dedhia Optimizing the inspection interval for high-reliability components whose examinations have a significant outage impact. Welds and similar components in nuclear power plants are subject to periodic examination under ASME Code, Section XI. Typically, examinations are performed during every ten-year inspection interval using volumetric examination techniques, or a […]
By: Dave Gerber and Terry Herrmann Environmentally-Assisted Fatigue (EAF) screening is used to systematically identify limiting locations for managing EAF effects on Class 1 reactor coolant pressure boundary components wetted by primary coolant. This article provides an overview of the methods developed and used by Structural Integrity (SI) for Class 1 components having explicit fatigue […]
