Master-Lee Engineered Products provides a user-friendly set of tools for the removal of flux thimbles .... the Flux Thimble Removal Tooling System.





The EPI system removes the highly radioactive flux thimbles from the Reactor Vessel side for disposal.  Underwater handling of the 30+ foot long section is meticulously done with the aid of our Deluxe AirGrips Package (Ball-Lock) and Flux Thimble Grapple Tool.  This tool has been engineered to easily position itself around the flux thimble, at which point a cam mechanism is actuated to securely grip the flux thimble for retraction.


To size the flux thimble into more manageable sections, a hydraulic 'C' Cutter System is attached to the end of our AirGrips 10' Bottom Mast Sections (Ball-Lock).  Once cut, the sections can be inserted into EPI's Debris Canister (optional) for transfer to the SFP. 


  • Available as a complete system or individually, the EPI Flux Thimble Removal Tooling System is a versatile package which can be incorporated into your standard inventory of outage maintenance tools.
