Implementation of a device circuit and conductor routing analysis database at Point Lepreau Generating Station

As a result of the Fire Probabilistic Safety Assessment performed in support of the refurbishment of the Point Lepreau Generating Station, all room locations for cables and conductors connected to safety significant devices were required to be identified. It was originally estimated that manual identification of these cable locations could take up to 100 man-years. Using a device circuit and routing analysis program, the room locations of these safety significant cables and conductors were determined in a fraction of that time. This paper describes the methodologies used, and the difficulties encountered, during the design and implementation of this program. (author)
