Calibration Facility and Tooling Station
The Project
Ontario Power Generation uses a variety of custom designed tools for inspection of the CANDU reactor fuel channels in the reactor cores. As part of a project to develop a universal type delivery system for the different tool types, for Bruce Power's Bruce Generating Station, there was a need to provide a system to calibrate, test, store and exchange reactor fuel channel inspection and maintenance tooling.
The Solution
In order to meet reactor access limitations and complex mounting area restrictions, Numet designed a very compact and modular system with an assembled size of 8' high by 10' wide by 20' long, weighing approximately 22,000 lbs.
The design incorporates a 72" p.c.d. ring gear to rotate the remotely driven 13 station magazine, the ability to remotely flood and drain a module with D2O, a pneumatic system to remotely operate various actuation cylinders, and removable stairs and platforms to facilitate the portability and installation of the equipment. It is designed for operation in a harsh environment with limited personnel accessibility.
Complete engineering analysis and registration was completed for the piping system and modules. Platforms, stairs, shields and guards are all designed to meet Canadian Occupational Health and Safety Act requirements.
Operation of the CFTS is remotely controlled via a Profibus network through a Programmable Logic Controller (PLC) using a graphic Operator Interface Terminal (OIT).
Numet's scope of supply included full simulation testing of the system's operation prior delivery to site.
