Crud Tolerant Fuel Channel Closure for Bruce GS A

Abstract

This development project was originated by Ontario Hydro because of the serious difficulties being encountered in replacing fuel channel closures by the fuelling machine (f/m) at Bruce Nuclear Generating Station A as a result of debris being present in the locking lugs and seal face area of the fuel channel end fittings. The design aimed at a mechanical means of scooping the debris with a modified channel closure which would replace the regular channel closure presently carried in the fuelling machine magazine as a spare.
