INSPECTION, ENGINEERING & TECHNOLOGY EXPERTISE FOR POWER PLANTS
Whether it starts with natural resources or a nuclear reaction, electricity is the lifeblood of our modern world. And the reliable operation of your facility is critical to providing the kilowatts that make our world go around. Over time, however, cracks, leaks and corrosion can keep your facility from operating at full capacity. With the high turnover and shortage of engineering talent and disjointed roles and responsibilities, do you have the expertise to identify and solve the problems? IIA has the experience, expertise, and turnkey engineering and inspection solution to help.
IIA combines engineering and inspection expertise that saves you time, money and stress. We offer engineering services that can be combined with conventional and advanced non-destructive examination (NDE) to pinpoint and analyze cracks, corrosion, erosion and other damage in equipment ranging from nuclear reactor pressure vessels to wind turbine rotors, and everything in between.
Whether you need help with routine examinations, a refueling outage, critical component examinations for license renewals, compliance issues or an unexpected equipment challenge, IIA can deliver the technical expertise and turnaround times you need.

NUCLEAR PLANT SYSTEMS & EQUIPMENT TESTING
We can help your plant run more efficiently in many areas.
BOLTING: THREADS IN FLANGE (TIF)
Our automated and manually deployable scanner system ultrasonically examines flange threads, and easily maneuvers onto and around guide pins or stud hole plugs. Our system accommodates large or small holes and is easily tailored to any flange architecture. Our safe and cost-effective solution does not require crane support — only a small operating crew.
We provide shroud horizontal and vertical weld examinations using our state-of-the-art technology: AIRIS-CS,™ Upper Shroud Scanner (USS) delivery systems, and a BWRVIP-qualified Phased Array UT (PAUT) data acquisition system.
DISSIMILAR METAL WELDS
We can deliver rapid ultrasonic examination of various pipe weld configurations and bidirectional scanning. Weighing less than seven pounds, our system is ideal for a single operator and its multiple link design and different length scan arms makes it compatible with different pipe sizes (4” and up) and configurations.
BWR STEAM DRYERS
The Steam Dryer Lifting Rod scanner is a manually deployable X-Y scanner with the ability to conduct vertical scanning and horizontal reference location scanning. The system includes the scanner and the Tomoscan III acquisition system and provides enhanced precision and examination coverage, increased reliability, and easy handling and maintenance.
Our IRIS system examines heat exchanger tubes using a rotating ultrasonic beam that results in a helical scan. It works by reflecting from the tube inside diameter (ID) and outside diameter (OD), and the time difference is then used to calculate the thickness.
We provide the highest quality ID and OD piping NDE examinations using versatile automated robotic systems and equipment for general weld examination, corrosion detection, mapping, pitting and wall-loss, PDI and general weld examinations, and screening and monitoring of casings.
REACTOR PRESSURE VESSELS
PDI-qualified examinations use fully automated state-of-the-art PAUT techniques for PWRs and BWRs for vessel shell welds, , nozzle-to-shell welds, nozzle-to-safe end dissimilar metal (DM) welds, and on safe end-to-pipe, as well as elbow welds.
STEAM GENERATOR NOZZLES
We developed a first-of-its-kind, remotely deployable Steam Generator Nozzle Examination Tool (SG-NExT) that enables a PDI-qualified phased array ultrasonic (PAUT) examination. SG-NExT minimizes exposure to high radiation fields Examination of these welds from the inside can result in significant dose and dollar savings
By using state-of-the-art dedicated industrial design turbine blade scanners, combined with our custom applications (e.g., 3-D simulations), we are able to provide the optimal PAUT probe delivery system, customized for specific turbine configuration. As a result, inspection solutions are accurate and efficient and can determine the ideal solution for field applications.
Certified in SNT-TC-1A (Level I, II and III) & CP-189 and in multiple NDE methods, including ASNT Level III, IIA uses our proprietary AIRIS TM 21 tool with our state-of-the-art NDE techniques. The AIRIS 21 can deploy via most tank manways.
We provide diagnostics and inspection services for a variety of valve configurations. Our patented PASS® Visualization software provides an easy, complete solution for Phased Array UT (PAUT) data analysis. We provide a 3D valve model that allows engineers to interpret and translate field data. An accompanying database tracks valve performance during inspection, allowing critical decisions to be made regarding operability and predictive maintenance — without disassembly.
BREADTH OF SERVICE
Fitness-for-Service (FFS) Evaluations
After a flaw or damage mechanism has been identified, our FFS evaluations assess the structural integrity of in-service equipment, such as tanks, piping and pressure vessels, to help plant owners make informed run-repair-replace decisions.
Finite Element Analysis (FEA)
Using sophisticated computer modeling software, we can accurately predict how a component will perform when subjected to real-world stresses, such as heat, vibration, or impact. You’ll receive accurate modeling data that you can compare against specifications, codes and regulatory standards.
Service Water System Evaluations / Tmin Calculations
We perform ASME-compliant flaw evaluations of Service Water piping. Combined with our engineering expertise in t-min calculations, IIA can clarify the parameters for safe operations.
IIA can help keep your plant safe and compliant by providing exams for:
- ASME Section XI examinations, including Appendix VIII (PDI) examinations
- Corrosion, pitting, and wall-loss detection
- Comprehensive Foreign Material Exclusion (FME) program
- General weld inspections, including unmatched elbow weld inspections
- ID and OD piping
- Various storage tanks
- Service Water Line Inspections
- Valve Diagnostics
- Reactor Vessel
CUTTING EDGE TECHNOLOGY
We are experts in the most advanced examination techniques available today. And we are always working to develop tooling and the preferred techniques of tomorrow. From ARMUT®’s high-resolution weld images to the AIRIS® RPV and tank robotic scanner, IIA has developed patented technologies that ensure we can meet any inspection challenge with confidence. Our patented technologies offer more innovative ways to inspect and retrieve qualified data. And because they require fewer crew members to deploy, they can aid in lowering radiation exposure. Some of our proprietary technology is used in lieu of radiography, which provides a safer testing environment while working with fewer on-site crew members.
PATENTED TECHNOLOGIES, TOOLING AND TECHNIQUES
Our patented ARMUT® system uses QR code film to inspect piping welds and complex geometry, delivering the highest data quality regarding elbow welds.
IIA’s AIRIS® is designed to thoroughly and accurately inspect components inside reactor pressure vessels (RPVs), as well as inspection of the CST and RWST
PASS® offers more reliable data regarding valve operability and predictive maintenance — without costly disassembly.
