Effective Foreign Material Exclusion (FME) is essential to successful maintenance and outage planning at both boiling water reactor (BWR) and pressurized water reactor (PWR) nuclear plants. Keeping things out of where they shouldn’t be is just as important as putting the right things in the right spot!

Tools, debris, and other foreign materials don’t belong in sensitive reactor systems or their components! They can cause flow restrictions, component damage, and potentially, unplanned outages or regulatory issues. Whether it’s a dropped tool, loose debris, or an unsecured rope, any foreign object can pose a risk.

Custom-Engineered FME Barriers

Preferred Engineering has decades of experience developing site-specific FME barriers that work seamlessly with existing plant layouts and outage plans. From pool covers to handrail-mounted barrier panels, our products are built to maintain the integrity of your FME zones.  We collaborate closely with Reactor Services, Radiation Protection, and ALARA teams to ensure that each barrier is developed, designed and manufactured for easy installation and effective, safe use.

Designed for your plant

Our FME barriers are designed to fit around existing installations, accommodating for outage equipment installations and use. We offer a range of materials including stainless steel, aluminum, colored polycarbonate sheets, and high-performance, fire-retardant fabrics to meet your plant’s specific requirements for durability, visibility, and fire safety.

Finally, our innovative rubber components allow hoses, ropes, and other temporary equipment to pass through barrier systems without compromising FME integrity. That means fewer workarounds and safer outcomes.

Supporting Both BWR and PWR Plants

Preferred Engineering FME barriers have been successfully deployed in both BWR and PWR environments. We understand the unique challenges each plant type presents, and we design accordingly.

From concept to installation, our goal is cleaner, safer, and more efficient outages. If you have challenges with your outage and maintenance needs, reach out to Preferred Engineering today to learn how our engineered solutions can improve safety and compliance at your facility.
