Flux Thimble Cutting - Flux Thimble Grapple

OVERVIEW

The HTS-designed Flux Thimble Grapple is the centerpiece of the HTS Flux Thimble Cut-Up Tooling Package. Engineered to maintain positive control of the irradiated “hot end” during all phases of removal, the grapple is built for safe, consistent performance in underwater environments. A pneumatically actuated lead-in and grapple jaw system ensures the thimble remains fully captured and aligned — providing even the most inexperienced operator with “success at depth.”
The grapple is also designed for full FME compliance, with enclosed mechanisms and no loose hardware, making it ideal for high-integrity pool and containment use.

KEY FEATURES

• Controlled Capture: Pneumatic lead-in mechanism guides the thimble directly into the jaws for secure engagement.

• Progressive Grip Strength: Specially designed jaws apply increasing grip as pulling force increases — even on stuck thimbles.

• FME-Compliant Design: Fully enclosed construction with no loose or detachable components ensures tool integrity in FME-sensitive zones.

• Operator-Friendly: Integrated lead-in improves success rates in deep, low-visibility, or first-time use environments.

• Critical Safety: Maintains control of irradiated components throughout handling and cutting to support event-free campaigns.

• Fully Pneumatic Operation: Enhances safety and repeatability with no manual gripping required.
