From 2015 to 2019 Structural Integrity Associates, Inc. (SI) worked with News & View, Volume 47 | Aircraft Impact Assessments for NUSCALE PowerNuScale Power,LLC. to develop structural details for and perform aircraft impact assessments of NuScale’s SMR Reactor Building.  The assessments were based on finite element analyses of various strike scenarios stemming from NEI 07-13 guidance.  ANACAP, a proprietary SI concrete constitutive model, was used in the finite element analyses.  Among other capabilities, the ANACAP model can capture multi-axial tensile cracking, compressive crushing with strain softening, and crack dependent shear stiffness.

News & View, Volume 47 | How To Make Knowing A Good Thing: Thinning Handbooks

By:  Stephen Parker and Eric HoustonNews & View, Volume 47 | TRU Compliance Expands into Physical Security | How To Make Knowing A Good Thing - Thinning Handbooks

SI has developed a process to mitigate the negative outcomes of piping examination.  One part of that process is Thinning Handbooks, which have resulted in direct savings in excess of $10 Million for one nuclear plant.

Examination of Safety Related Service Water piping is driven by a number of factors, all of which tend to converge on the objective of finding localized thinning prior to the thinning becoming a problem.  In other words, examinations are performed to eliminate the risk of a leak and ensure that the wall thickness remains greater than tmin (the minimum required uniform wall thickness).  However, the rules, regulations, and economic realities mean that only bad things happen from an exam regardless of what is found.

Properly inspecting plant piping and components for service damage is an integral part of proper asset management.  High energy systems constructed in accordance with ASME codes require appropriate inspections that are based on established industry practices, such as implementation of complimentary and non-destructive examination (NDE) methods that are best suited for detecting the types of damage expected within the system.  In any instance where NDE is used to target service damage, it is desirable to perform high quality inspections while at the same time optimizing inspection efficiency in light of the need to return the unit to service.  This concept is universally applicable to high energy piping, tubing, headers, valves, turbines, and various other power and industrial systems and components.

News & View, Volume 47 | Biofilms? MIC? What Are They?

By:  Edward Dougherty

News & View, Volume 47 | Biofilms? MIC? What Are They?Has the heat conversion efficiency of your heat exchangers degraded? Is the flow of your cooling water system being impeded? Are you repairing or replacing equipment due to localized corrosion causing through-wall failure? Inefficiencies and equipment failures are big problems in any industrial process, but the cause of the problem may be smaller than you think. You might have a biofilm problem. Bacteria floating in a cooling or process water can become colonies on wetted surfaces and can form robust biofilms over remarkably short times. Biofilms are collections of living and dead cells that are enclosed in an extracellular polymeric substance matrix secreted by living organisms. The unchecked growth of biofilms can significantly decrease thermal efficiency on surfaces as the biofilm acts as an insulating layer. Highly localized chemical effects can also be created that lead to microbiologically influenced corrosion (MIC).

A new program to help pipeline operators implement the Material Verification requirements in recently released pipeline regulation (Mega Rule)

On October 1, 2019, the Pipeline and Hazardous Materials Safety Administration (PHMSA) published the long-awaited Mega-Rule  (Part 1).  One of the major new requirements identified in these amendments is when missing traceable, verifiable, and complete records, operators must implement a Material Verification (MV) (§192.607) program.  MV requires operators of natural gas transmission pipelines, to develop and implement procedures to verify the material properties and attributes of their pipeline system.  Included in the new regulation for MV are:

  • News & View, Volume 47 | Material Verification IntelligenceDevelop procedures for conducting destructive and non-destructive testing
  • Define population groupings and implement sampling programs
  • Implement and document laboratory testing
  • Complete in situ and non-destructive evaluations (NDE)
  • Expand sampling if inconsistent results based on NDE and laboratory testing
  • Document program results and preserve for the life of the pipeline asset

News & Views, Volume 47 | Introducing Pegasus: Optimize Fuel Performance

By:  Vick Nazareth and Bill LyonNews & View, Volume 47 | PEGASUS State-of-the-Art Nuclear Fuel Behavior

The Pegasus code is a culmination of nuclear fuel behavior knowledge and experience that spans a period of over five decades. It is a total fuel-cycle simulation of fuel response from initial insertion in reactor to deposition in permanent storage. The goal of Pegasus is to treat, with equal fidelity, the modeling of fuel behavior during the active fuel cycle and the back-end cycle of spent-fuel storage and transportation in a single, self-consistent, and highly cost-effective analysis approach. In the active part of the fuel cycle, Pegasus’s superior three-dimensional thermo-mechanics, coupled with validated nuclear and material behavior models, and robust fuel-cladding interface treatment make it a high-fidelity predictor of fuel-rod response during flexible power operations and operational transients.

News & Views, Volume 47 | Metallurgical Lab Case Study: Corrosion Fatigue in WaterWall Tubes Increasingly A Safety Concern as Coal Plants Cycle

By:  Ben RuchteNews & View, Volume 47 | Metallurgical Lab Case Study- Corrosion Fatigue in WaterWall Tubes Increasingly A Safety Concern as Coal Plants Cycle

It is well known that conventional coal-fired utility boilers are cycling more today than they ever have.  As these units have shifted to more of an ‘on-call’ demand they experience many more cycles (start-ups and shutdowns, and/or significant load swings) making other damage mechanisms such as fatigue or other related mechanisms a concern. 

The most recent short-term energy outlook provided by the U.S. Energy Information Administration (EIA) indicates the share of electricity generation from coal will average 25% in 2019 and 23% in 2020, down from 27% in 2018.  While the industry shifts towards new construction of flexible operating units, some of the safety issues that have been prevalent in the past are fading from memory.  The inherent risks  of aging seam-welded failures and waterwall tube cold-side corrosion fatigue failures are a case in point.   It is well known that conventional coal-fired utility boilers are cycling more today than they ever have.  As these units have shifted to more of an ‘on-call’ demand they experience many more cycles (start-ups and shutdowns, and/or significant load swings) making other damage mechanisms such as fatigue or other related mechanisms a concern.  The following case study highlights this point by investigating a cold-side waterwall failure that experienced Corrosion Fatigue.  While this failure did not lead to any injuries, it must be stressed that the potential for injuries is significant if the failure occurs on the cold-side of the tubes (towards the furnace wall).

By:  Scott Riccardella, Bruce Paskett, and Andy Jensen

News & View, Volume 47 | Release of the First Safety of Gas Transmission Pipeline Regulation Mega-RuleOn 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-Rule1.  This new regulation is commonly referred to as the Mega-Rule, as it represents the most significant regulatory impact on gas transmission pipelines since the original Gas Transmission Integrity Management Program (TIMP) Regulation was issued in 2003.

General Overview
As a result of numerous transmission pipeline accidents in the late 1990’s, the congressional Pipeline Safety Improvement Act of 2002 required operators of natural gas transmission lines to create TIMP Plans to identify transmission lines in High Consequence Areas (HCAs), conduct risk assessments and manage the integrity of covered segments in HCAs  by conducting periodic integrity assessments. In 2010 through 2012, multiple incidents (Deep Water Horizon, San Bruno, California, Marshall, Michigan, Sissonville, WV) created a renewed focus on pipeline safety in Congress.
