Product Selection Differences for Electric Actuators, Nuclear Service

When selecting electric actuators for nuclear service applications, there are several key differences to consider compared to more general industrial applications. Here are some factors to keep in mind:

1. Safety and Reliability: In nuclear service, safety and reliability are of utmost importance. Electric actuators used in nuclear applications must meet stringent safety standards to ensure the proper functioning of critical systems, emergency shutdowns, and safety-related functions.

2. Radiation Resistance: Electric actuators operating in a nuclear environment must be designed to withstand exposure to radiation without degradation in performance. This requires special materials and construction techniques to ensure long-term reliability.

3. Seismic Qualification: Electric actuators used in nuclear power plants must be able to withstand seismic events without failure. This includes meeting specific seismic qualification requirements to ensure the actuator can continue to operate during and after an earthquake.

4. Environmental Conditions: Nuclear environments can be harsh, with factors such as high temperatures, humidity, and exposure to chemicals. Electric actuators selected for nuclear service should be able to operate effectively in these conditions without compromising performance or safety.

5. Regulatory Compliance: Electric actuators used in nuclear service must comply with strict regulatory requirements and standards set by organizations such as the Nuclear Regulatory Commission (NRC) in the United States or equivalent bodies in other countries. Compliance with these regulations is essential for safety and operational integrity.

6. Testing and Certification: Electric actuators for nuclear service often require extensive testing and certification to ensure they meet industry-specific standards and performance requirements. Manufacturers should provide documentation to demonstrate compliance with relevant standards.

7. Redundancy and Fail-Safe Features: In nuclear applications, redundancy and fail-safe features are crucial to ensure continued operation in the event of a failure. Electric actuators may need to have redundant systems or fail-safe mechanisms to prevent critical system failures.

When selecting electric actuators for nuclear service, it is important to work with reputable manufacturers with a proven track record in supplying products for nuclear applications. Additionally, consulting with experts in nuclear engineering and industry-specific requirements can help ensure the right choice for your specific needs.
