Engineering services include structural and stress analysis, fracture mechanics analysis and risk assessment, materials/metallurgical/corrosion evaluations, piping analyses, root-cause failure analyses, and others.

» Structural Integrity Overview
A new eight-page, full-color brochure offers an overview of all SI services, including SI's consulting engineering services for the nuclear, fossil, and pipeline industries, and specialized services for SI's Canadian clients. The brochure also includes a description of SI's Expert Solutions services for utility, industrial, legal, and insurance clients.

» ASME Code Case N-716
This one-page brochure briefly describes Risk-Informed In-Service Inspections (RI-ISI) as well as RIS_B™, a new streamlined RI-ISI methodology that can result in fewer inspections with no increase in plant risk. The associated ASME Code Case N-716 is discussed. SI played a key role in development of RI-ISI and RIS_B (Risk-Informed Safety-Based) methodologies by EPRI®.

» Generator Dovetail Analysis
SI's one-page brochure briefly discusses rotor wedge slot dovetail inspection issues regarding certain conventional and direct-cooled generator rotors manufactured from the early 1960s through the late 1970s, and lists related SI dovetail evaluation services — including eddy-current and linear phased-array inspections as well as stress and fracture mechanics analyses.

» Generator Retaining Ring Life Assessment
This one-page SI brochure describes the use of EPRI's RRingLife™ computer program to characterize the impact of flaws and other conditions on remaining life of 18-5 alloy generator retaining rings. RRingLife, developed by SI for EPRI, uses probabilistic life assessment to avoid wholesale ring replacements.

» Generator Rotor Dovetail Alternative Inspection
This one-page brochure details a generator rotor dovetail inspection approach developed by SI and EPRI as a lower-cost, shorter-schedule alternative to conventional inspections, which require rotor disassembly. The brochure lists features of SI's dovetail condition assessment package.

» Generator Shaft Keyway Cracking
This one-page brochure describes the phased-array ultrasonic inspection techniques developed by SI to detect generator shaft keyway cracking from the outside surface of the generator shaft without coupling disassembly. Also described are SI's evaluation and monitoring techniques for this type of cracking.

» Inspection of Solid Turbine and Generator Rotors
This one-page brochure describes the challenges of inspecting un-bored turbine and generator rotors, whether the rotors in question are vintage rotors or newer un-bored rotors, and presents SI's approach, which inspects the rotor's entire central volume via a sequence of angled linear phased-array scans.

» LPRimLife™ for Microsoft® Windows®
This one-page brochure discusses how LPRimLife™, a software code developed by SI for EPRI, can be used to estimate remaining life of low-pressure steam turbine rotors with blade-attachment stress corrosion cracking. LPRimLife features an easy-to-use Microsoft® Windows® graphical interface.

» Managing Buried Assets Programs for Nuclear Plants
SI's two-page brochure discusses the challenges involved in nuclear power plant relicensing, specifically those of managing buried assets to avoid corrosion for an additional 20 years of service. The brochure details SI's Managing Aging Piping (MAP) program for buried assets.

» Materials Science Center
This one-page brochure on SI's state-of-the-art Materials Science Center highlights the wide-ranging capabilities of the Austin, Texas facility, including laboratory and on-site failure investigations, material evaluations, engineering and failure analyses, and nondestructive testing. Some of the Materials Science Center's particular specialties include optical metallography, quantitative microstructural analyses, fractography, scale and deposit analyses, metal chemical analyses, cryo-cracking, and in-place metallography and replications.

» Steam Turbine/Generator Rotor Bore Inspection
This one-page brochure outlines SI's approach to steam turbine/generator rotor bore inspection, using a concurrent ultrasonic and eddy-current imaging technique to inspect the bore surface and near-bore region. SI's system employs advanced digital acquisition and signal processing to acquire and record data.

» Steam Turbine/Generator Rotor Forging Life Assessment
A one-page brochure briefly describes EPRI's SAFER-PC™, a computer code developed for stress and fracture evaluations of steam turbine/generator rotors. SAFER-PC combines transient thermal-elastic finite element stress analysis, fracture mechanics, and other data for its remaining life assessments. SI was involved in SAFER-PC's development, and uses the code extensively.

» Steam Turbine Rotor Blade Attachment Inspection
This one-page brochure describes SI's approach to low-pressure steam turbine rotor blade attachment inspections using a specially designed linear phased-array scanner. The approach offers enhanced detection and sizing of cracks in attachments, thereby enabling better management of run/repair/replace decisions.

» Steam Turbine Rotor Disk Keyway/Bore Inspection
A one-page brochure presents SI's inspection services for steam turbine rotor disk keyways and wheel bores of shrunk-on disks, both of which are susceptible to stress corrosion cracking. SI employs a specially designed linear phased-array scanner to detect and size cracks, resulting in improved detection and characterization over conventional multiple fixed-angle inspections.

» Turbine and Generator Inspection and Condition Assessment
This one-page overview brochure outlines SI's turbine and generator inspection and condition assessment services for rotor bores (machining services, visual inspection, concurrent ultrasonic/eddy-current inspection, and condition assessment); generator retaining rings (surface examination, computer-based data acquisition systems, assessments, and ultrasonic techniques); and turbine disks (computer-based data acquisition systems and flexible disk scanners).

» Ultrasonic Phased Array Examination of High-Density Polyethylene
This one-page SI brochure describes the challenges associated with maintaining metal piping, and how the nuclear power industry is selectively beginning to use High-Density Polyethylene (HDPE) piping for non-safety related applications.
