SL Delivers Major Tool System to support Darlington NGS Refurbishment

January 19, Hamilton, Ontario

This month, Stern Laboratories delivered twelve crates of parts to the Darlington Nuclear Generating Station.  The crates contained a complete ICFD Removal Tool System, and will be used to help safely refurbish Darlington’s unit 2 reactor.  The delivery was the culmination of a year-long contract with ES Fox.

The ICFD Removal Tool System, better known as the Chopper Tool, is a system designed and fabricated by Stern Laboratories for removing “In-Core Flux Detectors” (ICFDs) from a CANDU reactor.  These detectors are radioactive, and replacing them safely and quickly within the tight confines of the reactor’s containment system presents a difficult challenge for the refurbishment team.  The Stern Labs Chopper Tool operates remotely to pull detectors out of the core, reduce their volume, and transport them safely to a shielded Canister, all done with portable equipment that can be carried into place by two operators.

Chopper Tool Systems have been delivered to clients in Ontario, New Brunswick, China, Korea and Argentina.  The system’s commercial success demonstrates Stern Laboratories’ ability to provide unique solutions to the nuclear industry.  This month’s delivery to E. S. Fox included some custom modifications to make handling ICFD Canisters more efficient to for the big refurbishment job ahead.
