News & Views, Volume 49 | Code Compliance and the Modular Construction Trend

The modular construction industry is projected to grow globally at an annual rate of 6.9%, outpacing the growth of traditional construction.1  Modular construction has many advantages over traditional building methods, including improved quality control and shorter project durations. Factory-built systems are constructed in controlled environments with equipment and materials that are not feasible at congested job sites, and project schedules can be shortened when factory work and field work are performed in parallel.

However, modular projects may stumble without proper forethought: when fabrication takes place in a factory away from the jobsite, the building officials, inspectors, and engineers can have less oversight and less recourse to implement changes if issues are discovered in the field.  Code compliance may also be an issue when systems are designed by factory engineers rather than the engineer of record.  To mitigate these potential pitfalls, careful planning is required at the start of the project.

News & Views, Volume 49 | Autobook- Nuclear Physics Automation CodeBy:  Sasan Etemadi, P.E. and Mark Drucker, P.E.

The AUTOBOOK code reduces human errors, increases efficiency, and streamlines the reload analysis process

AUTOBOOK facilitates plant operation by providing nuclear power plant Reactor Engineers and Reactor Operators with cycle-specific information about the physics characteristics of the reactor core in a core data book document. Structural Integrity has created the AUTOBOOK computer code to automate the creation of this document.

AUTOBOOK is a Quality Assured code developed under a licensee’s software quality assurance (SQA) program. SI provides a full complement of SQA documents, including a Software Requirement Specification (SRS), a Software Design Description (SDD), Verification and Validation (V&V) Plan and Test Report, a User Manual, and Software Installation Instructions (SII).

News & Views, Volume 49 | The 4th Dimension- Lifecycle Assessment of Critical Structures

By analytically simulating the steps in the construction process, including the sequence of concrete placements, and tracking the history of the material behavior starting from initial placement, the potential for cracking is evaluated by comparing the time dependent stress and strains to the concrete cracking resistance and capacity.

Aging Infrastructure Issues

The infrastructure in the United States is aging and, whether publicly or privately owned, significant resources are required to repair, replace, or modernize it.  Due to the high costs associated with these efforts, owners need to identify structures with high risk-of-failure consequences and find the most cost-effective solutions for rehabilitation.  High consequence infrastructure includes:

  • Highway and railway bridges,
  • Roadways for intra and interstate transportation,
  • Dams, locks, and levees for flood control and cargo transportation,
  • High rise business, apartment, and condominium towers, and
  • Power generation and distribution facilities for Nuclear, Fossil and Hydro utilities.

Structural Integrity Associates | Structural Integrity Associates Achieves Milestone with Pegasus Code DevelopmentOn October 28th, the Structural Integrity (SI) Nuclear Fuel Technology Team achieved a major milestone in completing the first Verification & Validation phase in the development of its nuclear fuel performance and behavior code Pegasus©.  “This is a significant step by the SI Team” commented Vick Nazareth, SI Fuel Director.  “We have been developing Pegasus© since 2017 to incorporate cutting edge computational technology and four decades of fuel behavior modeling and analysis expertise into a software program”.  The code addresses a need for deeper fuel integrity insights within the nuclear industry to achieve next level fuel performance and licensing.  Dr. Joe Rashid, Scientist and Senior Technology Developer of the code added “this code will analyze fuel behavior through the entire fuel cycle from initial startup to used-fuel storage”.

SI announced the development of Pegasus© in the SI newsletter in 2019, Introducing Pegasus: State-of-the-Art Nuclear Fuel Behavior with the objective of enhancing the fidelity of fuel behavior and performance in support of advanced fuel technologies.  The Pegasus© code will go through additional validation testing over the next several months to meet a production roll-out in early 2021 in support of fuel performance behavior analysis across a broad spectrum of light water reactor and advanced reactor fuel designs.

” I am proud of the SI Fuel Team”, said Mark Marano, SI CEO.” This milestone exemplifies our ability to provide innovative structural integrity solutions for clients across structures, systems, components, water chemistry and nuclear fuel.”

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:

  1. ­Are current reinspection guidelines compliant with industry requirements?
  2. ­Are there components where reinspection intervals could possibly be extended?

News & Views, Volume 48 | Acoustic Resonance

By: Mark Jaeger and Andrew CromptonNews & View, Volume 48 | Acoustic Resonance

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, nothing. Blow too soft, nothing.  When done just right, the bottle produces a sound (audible vibration).  Just like that, you have acoustic resonance.  Every wind instrument in a band uses acoustic cavity resonance to produce music.  Take a piece of flexible hose, spin it in the air until it whistles, again, acoustic resonance.  When an acoustic cavity resonance happens inside piping systems, especially those with high energy flow, those seemingly harmless vibrations we illustrated above can cause serious damage.  This phenomena can occur in nearly any industry, sometimes with benign consequences and other times with catastrophic results.

INDUSTRY CHALLENGE

News & View, Volume 48 | Plant Materials Aging and Degradation

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, failures still occur. With reactors being licensed to operate for periods up to 60 years, with further extensions under consideration, and power uprates being planned, many of the plant systems, structures, and components will be expected to tolerate more demanding environments for longer periods. The longer plant operating lifetimes may increase the susceptibility of different systems, structures, and components to degradation and may introduce new degradation modes.

While all components potentially can be replaced, decisions to simply replace components may not be practical or the most economically favorable option. Therefore, understanding, controlling, and mitigating materials degradation processes and establishing a sound technical basis for long-range planning of necessary replacements are key priorities for extended nuclear power plant operations and power uprate considerations. https://www.energy.gov/ne/materials-aging-and-degradation.
