SLARette Mark 2 System

Abstract

The SLAR (Spacer Location and Repositioning) Program has developed the Technology and Tooling necessary to Locate and Reposition the Fuel Channel Spacers that separate the Pressure Tube from the Calandria Tube. The In-Channel SLAR Tool contains all the Inspection Probes and is capable of moving Spacers under remote control. The SLAR Inspection Computer System translates all Eddy Current and Ultrasonic signals from the In-Channel Tool into various graphic displays. The In-Channel SLAR Tool can be delivered and manipulated in a Fuel Channel by either a SLAR Delivery Machine or a SLARette Delivery Machine. The SLAR Delivery Machine consists of a modified Fuelling Machine and is capable of operating under totally remote control in automatic or semi-automatic mode. The SLARette Delivery Machine is a smaller less automated version which was designed to be quickly installed, operated and removed from a limited number of Fuel Channels during regular Annual Maintenance outages. This paper describes the Design and Operation of the SLARette Hark 2 System.
