Hitachi- from the country that brought the world Fukushima
We feel very sad for the people of Japan who want to end nuclear energy whilst a potential new government and big business are desperate for it

No Fukushima at Oldbury

No to Fukushima at Shepperdine!

E-on/RWE and the cooling tower saga

A local persons contribution to the cooling tower issue at the Shepperdine site:-

The Oldbury/Shepperdine site is the only site proposed not on the sea, All the others will use sea water to cool the condensate from the turbines and therefore not need cooling towers. Because the Severn is tidal at Oldbury there is no water when the tides out and a resevoir, as used for the original power station, is not feasable. (silting up, size etc) The high cooling towers, which use natural convection, are probably (and should be) being rejected on visual grounds . The remaining alternative of forced air cooling was said to require 3% of the station output to drive the fans! This will mean something like 100 megawatts of electric being thrown away. Thats about half the output of one of the existing reactors! Millions of £'s of electric wasted to pump waste heat into the sky when it could be safely put into the ocean. They would probably be wasting something like the output of 10 wind farms similar to the one proposed locally.
Also the size of the cooling fans proposed on the movement of so much air and steam must have detremental effects locally. 100megawatts of fans cannot be silent! Does it rain down wind? Is it warmer locally. Cloudy?
Of course the German owners of E-on/RWE are used to these cooling systems. Why, because the industrial areas of Germany are so far from the sea they have no choice.
