The AC Device for Repositioning of Garter Springs in CANDU Reactors

Abstract

The AC Device represents the key component which makes the SLAR (Spacer Locating and Repositioning) system function. The AC Device produces a continuous electromagnetic force on the spacer in the axial direction when ac power is applied, without any adverse effects on the channel integrity. The AC Device or LIM (Linear Induction Motor) was proven to be safe and easy to operate in the hostile environment of a commissioned CANDU reactor, and is currently being manufactured by Ontario Hydro Research Division for field implementation of the SLAR program.
