Re: someone please explain
I was told a story by a shift manager at Sellafield of a time when their water treatment /pumping station which supplied the cooling systems on site with freshwater from Wastwater was being taken offline for maintenance. As you can probably imagine, they do lots of testing to make sure they know exactly what's in that water before using it in the non-radioactive side of the cooling systems.
They finally get some temporary pumps hooked up, and some specialist filter systems which were looked for all the world like road tankers, and start doing some analysis on the water going in and out of the filters.
Turns out that the lake water going in was so pure that it was cleaner than after it had been prossesed in the new filters, and so in a remarkable display of common sense, they did away with the temporary filters!
