Simplify and Streamline your Shroud Head Bolt Latching/Unlatching

The latching/unlatching of shroud head bolts is a critical task during boiling water reactors (BWRs) refueling outages.
Traditional methods for assembly and disassembly can be time-intensive and consume overhead crane time. To address these challenges, Preferred Engineering has developed an innovative shroud head bolt wrench designed to streamline the process and enhance operational flexibility.
The Preferred Engineering Shroud Head Bolt Wrench sets a new standard for nuclear maintenance tools by combining ease of use, versatility, and convenience. Its design eliminates reliance on the overhead crane and is optimized for high-torque applications. This tool enables technicians to complete tasks faster, safer, and more effectively.
Ease of use
With the Preferred Engineering Shroud Head Bolt Wrench, technicians can stage and demobilize the tool without depending on crane availability. The J-Slot style connections ensure fast and secure assembly, while anti-rotation protection adds a layer of reliability, ensuring the connections stay tight during use, even in challenging conditions.
Optimal Spring Cup Compression
Each section of the wrench is designed with partial buoyancy chambers that allow a pocket of air to be trapped inside the pole sections while submerged in the reactor water. The fully submerged weight of the Shroud Bolt Wrench assembly is 55-60 lbs., which is optimal for maintaining spring cup compression while making it easy for technicians to manipulate the full assembly, while preventing streaming.
Convenience
The Shroud Head Bolt Wrench is designed with rest collars, allowing for staging on support stations without the need to secure the poles with clamps. The optional storage box also protects the components from damage and loss, ensuring the wrench set is always ready when needed.
