History of Lepreau 2 Since 1974

Abstract

The 1974 Point Lepreau layout showed four CANDU 6 units with CW intake for the first pair of units. The first CANDU 6 was to be built at Gentilly 2, with Lepreau as a copy of G2 except that the layout was for two units with a common Main Control Room. The Lepreau 1 MCR was relocated resulting in the steam lines passing over the MCR of unit 1 and also near the MCR of the future unit 2. 1984 a Lepreau 2 layout was prepared using the existing CW intake and discharge. This layout was refined in 1986 so that the unit 2 MCR was away from the main steam lines of either units 1 or 2; also that a common external event could not impact both the MCR and Secondary Control Room of unit 2. In 1991 a layout was prepared of the CANDU 3 as Lepreau unit 2.
