Abstract

This paper will look at the development of a next generation inspection system for CANDU pressure tubes. The inspection system will be an autonomous crawler and will incorporate a full pressure closure plug which will not require the use of the current Universal Delivery Machine (UDM). By not requiring the UDM this new inspection package will allow for the potential of multiple inspections simultaneously, as well as freeing up the fueling machine bridge for other work. In conjunction with this new inspection system, an MCNP [1] simulation of the offline core conditions is being developed. This simulation will allow for estimates to be made of the dose that the inspection system will encounter, thereby allowing for more accurate prediction of component lifetimes.
