me capital costs estimated for the DHSR and the PWR by major (two-
digit) accounts are given in Table 32. A further breakdown (for three-
digit a@co%mts), which aiso includes the estimate for the coaa-fired
plant, is given in Appendix A (Table A.1).
ule for the DMSR (adapted to the CONCEPT V cash €How schedule) is also
given in Appendix A (Table ik.2).

The capital costs of the fuel treatment
facilities are not included here but are taken into account in the fuel
cycle cost (see Sect. 5.3.4). However, space and equipment for handling
the coolant salt are included in the reactor plant estimates.
The DXSR is estimated to cost $653 million, or about .$65O/kWe in 1978
dollars. This compares with about $600/kWe for a PWR plant and $38O/kWe
for a coal plant without flue-gas cleaning.
