Canadian nuclear projects pave way for size increase
The number of design options available to customers of the CANDU pressurized heavy-water (PHW) reactor system is in the process of being extended as Atomic Energy of Canada Ltd puts together the preliminary drawings for a 1200 MW(e) unit. Although the extrapolation from the 500-, 600-, and 750-MW(e) sizes epitomized by Pickering, Gentilly-2, and Bruce was requested by Ontario Hydro, that is to date the largest single devotee of the CANDU concept, the provincial utility is still not yet ready to order a 1200 MW(e) nuclear steam supply system for its grid. The utility is balancing two objectives: it wants to gain the econoniies of scale without sacrificing the reliability entailed in repeats of an existing design. It has been comparing since 1971 the cost reduction of plants identical to those previously constructed with design improvements to Bruce and with selection of the 1200 MW(e) size. Ontario Hydro is already committed to duplicating the existing units at Pickering, to building more 750 M(W(e) reactors at Bruce, and to installing at least one more series of 750s at Bowmanville.
