Cooling systems addendum: capital and total generating cost studies

Technical Report ·
OSTI ID:6275373
These studies present the capital and total generating costs for alternate cooling systems designed for six power plants--1200 MWe (pressurized water reactor, boiling water reactor, high sulfur coal-fired, low sulfur coal-fired) plants and 800 MWe (low-sulfur coal-fired and high-sulfur coal-fired) plants. In these base-capital cost studies, all of the plants are designed using mechanical-draft evaporate towers. Alternate cooling systems evaluated include: once-through, fan-assisted natural-draft towers, and natural-draft towers. These alternative cooling systems represent viable designs from both an economic and engineering standpoint. The estimated total base construction costs for the six plants incorporating the alternate cooling systems are summarized. Capital cost and fuel cost vary with each cooling system as compared to the base case; i.e., mechanical-draft evaporative towers. The once-through cooling systems have the lowest capital cost of the alternate systems evaluated.
