Nuclear power station cooling - using large natural water supplies eg lake at high altitude

摘要

Water pumped from the lake through the exhaust steam condenser, following the turbine, is fed back into the lake at its upstream end over a turbulent slope where the first phase of heat exchange with the cold, high atmos. Takes place. The second phase of heat exchange is by evaporation from the lake surface. Net heating of lake water reduced fro min. ecological damage.
