Thermal Mitigation Project at Savannah River

Question: Describe the needs that are to be met by the requirements of project 87-D-156, Reactor Effluent Cooling Water Thermal Mitigation.

Answer: The major sources of thermal effluents at the Savannah River Plant are the cooling water discharges from the production reactors, C and K, and the D Area coal-fired powerhouse. Although the production reactors have operated for approximately 30 years, at present, the discharge from these facilities do not meet the temperature limits prescribed by the State of South Carolina's standards. The Department of Energy has developed this project to enable operations to comply with these standards and to meet the requirements of a Consent Order between DOE and the State of South Carolina's Department of Health and Environmental Control.

Question: What is the total cost of project 87-D-156?

Answer: $109 million.

The total project cost for project 87-D-156 is

Question: What cost/benefit analysis has been performed on requirements of project 87-D-156?

Answer: The Department of Energy has performed a cost benefit study and has published the results which describe the systems which can best implement compliance with the water quality standards. As a result, DOE is considering the construction and operation of once-through cooling towers for C and K Reactors and implementation of increased coolant flow with mixing for the D Area powerhouse.

Question: What alternative measures have been analyzed to the use of these cooling towers?

Answer: The Department of Energy has examined alternatives which improve on the existing situation and which either meet or fail to meet the full requirements of the existing standards. Of the alternatives which meet the standards, cooling lakes, recirculating cooling towers, once-through cooling towers, and combinations of these have been evaluated. Of the alternatives which would significantly improve thermal discharges but which would not meet the standards, DOE has examined spray canals, lakes, energy recovery systems, and combinations of these.

Question: What is the environmental impact on the Savannah River site of having the proposed cooling towers?

Answer: The proposed project will require 1,125 to 1,600 acres of land. This includes flooding of 700 to 815 acres of upland hardwoods and pines under the new holding ponds. The equivalent of 50,000 barrels of crude oil will be consumed each year to power the fans and pumps to be installed. There will also be increased fogging due to the moisture discharged into the atmosphere by the

towers.
