Effective shielding protects workers and reduces radiation exposure during fuel movement in nuclear power plants. Preferred Engineering’s Fuel Transfer Canal Shield, also known as the Cattlechute, is specifically designed to support ALARA principles by minimizing exposure while maintaining efficiency during fuel transfers.

Safer Fuel Transfers

As fuel bundles are transferred through the fuel slot, radiation levels can increase in adjacent areas of the reactor building. The Cattlechute system uses ASTM B29-compliant lead, which is 99.94% pure, to provide maximum attenuation and help shield those surrounding areas.

In addition to radiation protection, the Cattlechute is built for clean operation. It is lined with polished stainless steel and constructed with continuous welds to prevent contamination traps. This smooth, coating-free surface is easy to decontaminate, reducing cleanup time and supporting more efficient maintenance schedules.

Optional Strongback for More Support

To further support ALARA goals, Preferred offers a remotely operated lifting Cattlechute Strongback. This feature eliminates the need for spreader bars and reduces the need for workers to be near the shield during installation or removal. By limiting time spent in high-dose areas, plants can lower cumulative radiation exposure and improve overall safety outcomes.

Collaboration Enables the Best Designs

Preferred Engineering designs its shielding solutions with input from experienced nuclear professionals. The result is a system that not only meets shielding requirements but also contributes to safer, faster, and more efficient plant operations. For facilities looking to improve radiation safety during refueling activities, the Fuel Transfer Canal Shield Cattlechute offers a proven and practical solution.
