Safety in nuclear power plants is a top priority, and minimizing radiation exposure is essential. With the adoption of robotics and indoor drones, this reduction is becoming increasingly feasible. Learn how Flyability’s drones, represented in Brazil by XD4Solutions, are revolutionizing nuclear inspections and helping meet ALARA standards.
What Is the ALARA Principle?
In the U.S., the ALARA principle (As Low As Reasonably Achievable) requires nuclear plant operators to minimize radiation exposure as much as possible, considering factors such as:
- The state of technology;
- The economic feasibility of improvements;
- Health and public safety benefits;
- Relevant socioeconomic factors.
ALARA’s intentional flexibility encourages continuous innovation, such as indoor drones, which can significantly reduce workers’ exposure.
Seven Days of Work for a 20-Minute Inspection
Nuclear inspection is one of the most meticulous processes in the world. For example, former NDT inspector Michael Vanovermeir describes his experience of seven days of work for a single 20-minute inspection:
- 3 days of training;
- 2 days of inspection preparation;
- 1 day to perform the inspection;
- 1 day for debriefing and improvement analysis.
This process highlights how seriously ALARA is taken. Even reducing exposure by a few seconds can be crucial.
How Robotics Reduces Radiation Exposure
Strategies to minimize radiation exposure follow three key principles:
- Time – Reducing the time spent in irradiated environments.
- Shielding – Using protective materials.
- Distance – Increasing the gap between personnel and irradiated areas.
Among these approaches, robots and indoor drones are essential for increasing distance and reducing exposure time, making inspections more efficient and safer.
Elios 3: The Indoor Drone for Nuclear Inspections
The Elios 3, developed by Flyability, is designed to fly in confined indoor environments, tackling inspection challenges in nuclear plants. Its design includes:
- A protective cage for safe collision handling;
- High-quality visual data collection;
- The ability to operate in hard-to-reach spaces.
This drone allows inspectors to analyze structural conditions without physically entering hazardous areas, drastically reducing radiation exposure.
Elios 3 RAD: Remote Radiation Detection
The Elios 3 RAD takes safety to the next level by incorporating radiation sensors that provide real-time measurements during flight. This drone offers:
- Three interchangeable sensors for different radiation levels;
- Radiation dose mapping to identify critical areas;
- Precise measurement in Rem and Sv units, facilitating dose planning and decision-making.
With the Elios 3 RAD, operators can avoid unnecessary worker exposure, reducing risks and optimizing inspection protocols.
