Exelon Clearsight used the Elios 2 for an ASME XI nuclear containment building inspection, saving over 300 billable hours. The project was completed one month faster and required only one qualified inspector instead of three.

Key Benefits at a Glance

Introduction

Nuclear inspections are some of the most complex and high-risk tasks in the industry. They involve strict protocols and must be conducted with precision to ensure the safety of both workers and the environment. One of the most challenging types of inspections is the ASME XI inspection of a nuclear containment building, which requires a thorough visual check of every square inch of concrete surfaces.

These inspections are typically done manually, requiring teams to use scaffolding, rope access, cranes, and other equipment to reach difficult areas. This not only increases costs but also exposes workers to significant risks, including falls and exposure to hazardous environments.

For example, during a past inspection, two inspectors were left stranded 280 feet in the air when a crane malfunctioned. A helicopter rescue was required to bring them down safely. These incidents highlight the dangers involved in traditional methods.

Given these challenges, many companies are now exploring safer and more efficient alternatives—like drone-based inspections. That’s where Exelon Clearsight stepped in, using the Elios 2 to perform an ASME XI inspection with remarkable results.

Customer Needs

Traditional ASME XI inspections are expensive, time-consuming, and dangerous. Inspectors often have to climb scaffolding, rappel through tight spaces, or stand on cranes, all while collecting visual data manually. This method is not only inefficient but also poses serious safety risks.

Recognizing these issues, a manager at a nuclear facility decided to explore a new approach. Instead of relying on manual methods, they turned to Exelon Clearsight, a trusted inspection expert, to conduct the inspection using a drone.

This decision was driven by the desire to reduce risk, save time, and lower costs. With over 40,000 square feet to inspect, the task was daunting—but the potential benefits of using a drone were clear.

Not only would it eliminate the need for physical access to dangerous areas, but it would also allow for more accurate and detailed data collection. It was a bold move, and one that had only been attempted a few times before.

Solution

Exelon Clearsight chose the Elios 2, a rugged, enclosed drone designed for extreme environments. Its unique cage design allows it to get close to structures without risking damage, making it ideal for inspecting concrete walls inside a containment building.

With its advanced imaging capabilities and durability, the Elios 2 enabled the team to collect high-resolution images and detailed measurements efficiently. This allowed them to cover the entire structure in record time while maintaining accuracy and safety standards.

Results

So, did Exelon Clearsight successfully complete the ASME XI inspection using the Elios 2? The answer is a resounding yes.

In just two weeks, a team of four inspected the entire 40,000-square-foot structure, capturing high-resolution photos of over 150 areas of interest. The result was a comprehensive report that included detailed defect analysis and photogrammetric measurements.

Benefits of Using the Elios 2

Here are the key advantages Exelon Clearsight delivered by using the Elios 2:

• Safety: No personnel needed to work at height or in confined spaces, reducing the risk of accidents.
• Speed: The inspection was completed in two weeks instead of six.
• Work Hours: Only one qualified inspector was needed, rather than three.
• Access: The Elios 2 could maneuver into tight spaces and capture high-quality images up close.
• Data Quality: The drone provided more detailed and accurate data than traditional methods.
• Project Complexity: Fewer people and less equipment were needed, simplifying the overall process.

Conclusion

Exelon Clearsight’s use of the Elios 2 in this nuclear containment building inspection proves that drones can meet even the most stringent requirements of the ASME XI code. Not only did they save time and money, but they also improved safety and data quality.

Now, the team is looking to apply these methods to future inspections, helping to avoid hundreds of hours of dangerous work and downtime. This case study shows how technology like the Elios 2 can revolutionize the way we inspect critical infrastructure.

The potential for expanding this approach to other structures—like bridges, tunnels, and industrial facilities—is vast. As industries continue to prioritize safety and efficiency, solutions like the Elios 2 will play a vital role in shaping the future of inspections.
