When safety is critical and efficiency runs a close second, your team needs innovative
maintenance solutions that cover all the bases. The Fuel Transfer Tube Closure System
(FTTCS) from Preferred Engineering is a breakthrough in safety for your PWR refueling
outage.

This patented solution was designed with the input of site RP and ALARA teams
resulting in a system that not only cuts critical path time but also drastically reduces
dose by removing the need for worker entry into the deep cavity.

No Deep Cavity Entry. No Double Plastics. All the Safety.
Traditional fuel transfer tube closure methods often rely on complex, time-consuming
procedures that require personnel to physically enter the fuel transfer cavity. This
system is installed and removed from the refuel floor, keeping personnel out of high-
radiation zones and reducing exposure across the board.

Eliminating the use of double plastics means shorter job duration and lower exposure.
With all maintenance also performed topside, teams avoid heat exhaustion and
confined space hazards.

Designed for ALARA, Built for Efficiency
Preferred Engineering has built its reputation by working side-by-side with nuclear
professionals. The FTTCS embodies this collaboration with features like:
– No modification required to the existing fuel transfer tube flange
– No external power required while the system is in place
– Hydraulics powered by demineralized water
– Stainless-steel construction for easy decontamination

Proven in the Field
The FTTCS has been successfully installed at two U.S. nuclear units with 60” flange
diameters, integrating with modern infrastructure without unexpected installation
challenges. More importantly, it’s been proven to save time and reduce dose during the
most critical phase of the outage schedule.
