A story in today’s USA Today suggests problems in the south with lack of water and cooling of nukes.
In NJ we have a problem with cooling at the Oyster Creek plant. Two ways to use water – one is to cool directly, taking water from a source, heating it up and returning it (hopefully not hot enough to cook fish). The second is to take water and evaporate it. The second is powerful, but actually consumes the water!!! So as water becomes scarce (and warm), which is the least harmful way to cool a power plant? mrm
From M. Khan:
… a new way to cool nuclear reactors which would supposively save upto 98% of water used by existing nuclear reactors… being built in Southern Maryland – scheduled to be up and running by 2015 (joint venture between Constellation energy and a french company) – a similar hybrid cooling tower was built in West Germany back in 1988
They call it a hybrid-cooling tower… what is it exactly a hybrid of? How does it work differently than a traditional tower? It uses fans… but wouldn’t that increase the evaporation rate, as opposed to conserving it? -jk
I was able to find a “hybrid type” cooling tower from SPX, apparently they use a heat exchanger to pull heat from the cooling water into an air-stream, which can help curb evaporation. -jk
