Custom EDM Power For Nuclear Thermal Sleeve Replacement

Remote, submerged spark-erosion technology engineered for in-situ reactor servicing with reduced debris and ALARA-aligned operation.

THE APPLICATION:

A Repair Process Designed Around Reactor Constraints

Flow-induced vibration can wear thermal sleeve flanges relative to the reactor vessel closure head, allowing the sleeve to interfere with control rod drive components.

Titan engineered custom power supplies that integrate with remote delivery tooling and operate through long cables under primary-coolant immersion.

THE CHALLENGE:

Safety, Containment, And Outage Time Converge

01

Foreign Material Exclusion

Mechanical chips in the coolant loop can threaten fuel assembles and are difficult to capture.

02

ALARA Exposure

Work beneath an irradiated closure head must minimize direct personnel access and dose.

03

Submerged Operation

Spark control must remain stable through long umbilicals in primary coolant.

04

Remote Alignment

Tooling must sense position and compensate inside the CRDM housing without contact.

THE TITAN SOLUTION:

Custom Pulse Power At The Heart Of Remote Repair

Titan adapted spark generation, gap sensing, probing, and control logic to the nuclear repair system’s delivery architecture and environment.

01

POWER SUPPLY

Custom Titan EDM Generator

Fine-tuned waveforms drive controlled spark erosion through long umbilical cables to the remote tool head.

  • Stable long-cable delivery
  • Fine waveform control
  • Tooling integration

02

PROCESS

Submerged Spark Erosion

Primary coolant water is the dielectric while the process eliminates cuter binding deflection and stress.

  • Filterabile microscopic swarf
  • Zero cutting force
  • Underwater removal

03

CONTROL

Adaptive Remote Operation

Arc sensing adjusts pulse duration while remote probing detects alignment and corrects coordinates.

  • Dynamic gap control
  • Hands-free sensing
  • Low-dose remote operation

THE ENGINEERED PLATFORM:

Remote EDM Power + Control

The Titan generator is part of the complete field-service system. Adaptive pulse control keeps the remote cut stable while automated sensing supports precise work from a lower-dose control location.

LONG-UMBILICAL RECOVERY
PRIMARY-COOLANT DIELECTRIC
DYNAMIC ARC CONTROL

THE RESULT:

Controlled - In-Situ Cutting With Dramatically Smaller Debris

EDM converts solid metal into micro-sized swarf captured by filtration, while remote operation reduces direct personnel exposure and avoids mechanical tooling forces.

01

FME Risk Reduction

Filtered microscopic swarf replaces the large chips created by milling or drilling.

02

ALARA-Aligned Operation

Technicians control the automated cut from lower-dose containment stations.

03

Shorter Intervention

In-situ severing targets approximately two days per location without complete disassembly.
