Computer Simulation of Fuel Channel Replacement

Abstract

Fuel Channel replacement can extend the life of existing CANDU reactors but has previously been time consuming and expensive. Simulation of CANDU fuel channel replacement can reduce the cost of developing faster methods of replacing channels in new and existing reactors. Computer simulation software for modelling the work environment and replacement process is now available on very powerful medium cost workstations. The techniques of modelling and expected results are described in this paper in the context of the planned retubing process for the CANDU 3 reactor.
