News and Views, Volume 50 | What’s All the Buzz About Hydrogen!

By:  Daniel Peters (SI) and Thomas Pastor (HSB Global Inspection & Engineering Services) A recent news story reported: Hydrogen initiatives are accelerating globally. 200+ large-scale projects have been announced across the value chain, with a total value exceeding $300 billion 30+ countries have national hydrogen strategies in place, and public funding is growing Anyone who […]

High Energy Piping Monitoring

High Energy Piping Monitoring SI moves beyond the pilot application of a High Energy Piping monitoring program designed to reduce operational risk and optimize maintenance activities. SI has successfully implemented the initial application of an integrated monitoring solution that provides insight into damage evolution and operational risk using real-time data and automated engineering intelligence. This […]

News & Views, Volume 49 | Inspection Optimization: Probabilistic Fracture Mechanics

By:  Scott Chesworth (SI) and Bob Grizzi (EPRI) The goal was to determine whether the frequency of current inspection requirements was justified or could be optimized (i.e., increase the interval of certain inspections to devote more attention to higher-value inspections and thereby maximize overall plant safety). Executive Summary Welds and similar components in nuclear power […]

News & Views, Volume 49 | Materials Lab Featured Damage Mechanism: Soot Blower Erosion

By:  Wendy Weiss Soot blower erosion (SBE) is caused by mechanical removal of tube material due to the impingement on the tube wall of particles entrained in the “wet” blower steam. As the erosion becomes more severe, the tube wall thickness is reduced and eventually internal pressure causes the tube rupture. Mechanism SBE is due […]

News & Views, Volume 49 | Rapid Assessment of Boiler Tubes Using Guided Wave Testing

By:  Jason Ven Velsor, Roger Royer, and Ben Ruchte Tubing in conventional boilers and heat-recovery steam generators (HRSGs) can be subject to various damage mechanisms.  Under-deposit corrosion (UDC) mechanisms have wreaked havoc on conventional units for the past 40-50 years and have similarly worked their way into the more prevalent combined cycle facilities that employ […]

News & Views, Volume 49 | Piping Fabricated Branch Connections

By:  Ben Ruchte Fabricated branch connections represent a common industry issue in combined cycle plants. Many are vulnerable to early damage development and have experienced failures.  Despite these challenges, a well-engineered approach exists to ensure that the baseline condition is fully documented and a life management plan is put in place to help reduce the […]

News & Views, Volume 49 | Attemperator Monitoring with Wireless Sensors: Risk and Cost Reduction in Real Time

By: Jason Van Velsor, Matt Freeman and Ben Ruchte Installed sensors and continuous online monitoring are revolutionizing how power plants manage assets and risk by facilitating the transformation to condition-based maintenance routines. With access to near real-time data, condition assessments, and operating trends, operators have the opportunity to safely and intelligently reduce operations and maintenance […]

News & Views, Volume 49 | Mission Critical Applications to Support the Mega-Rule

By:  Scott Riccardella, Bruce Paskett, and Steven Biles On October 1, 2019, the Pipeline and Hazardous Materials Safety Administration (PHMSA) published amendments to 49 CFR Parts 191 and 192 in the Federal Register, issuing Part 1 of the Gas Transmission Mega-Rule.  This new regulation is commonly referred to as the Mega-Rule since it represents the […]

News & Views, Volume 49 | PEGASUS: Advanced Tool for Assessing Pellet-Cladding Interaction

By:  Bill Lyon, PE and Michael Kennard PEGASUS provides a fully capable computational environment to solve the unique, detailed 3D analyses required for the evaluation of PCI. In the current economic environment in which nuclear units compete with less costly energy sources, a quicker return to full power correlates to more power generated and increased […]
