pop quiz.. some of the photos recently have show rusty objects found strewn about,,, and have said. .they could be fuel elements.. so.. qstn.. how did they get all rusty looking?

the seawater they sprayed was already polluted ? @dean

pollutants in seawater remaining after evaporation?
by elainekirk 4/16/2011 7:08:25 PM

well .. I think it's a combination of all that and the temperatures caused some to begin oxidation... in a normal spent fuel pool.. they have rigid chemistry controls.. to keep the water the same as the chemistry in the reactor.. so even tho the fuel elements are old.. they are still good to use in the reactor..

amazing to think that much rust or oxidation has occured in such a short time... I doubt the dry storage cask elements look like that

What was the initial seawater pumped through?

YEH Peter... I had thought the oxidation would have been sort of a whitish color on stainless. intersting

I know in ferrous metals that oxidation can make a rust color but now sure about the material for fuel elements..
by dean 4/16/2011 7:15:58 PM

like the zircaloy,, and stainless

elaine, the sea water is desalinated and treated to make the chemistry requirements for the vessel

I meant the emergency dosing with hoses dean that wasnt purified ..or is it possible the redness was already present?
by elainekirk 4/16/2011 7:18:39 PM

elaine.. correct.. there had to have been some burning or near burning in the spent fuel pools which could have discolored and then the yuky seawater came in with all the polutants and make added to the chemistry to turn them rust looking

Uranium was also used in photographic chemicals (especially uranium nitrate as a toner),[7] in lamp filaments, to improve the appearance of dentures, and in the leather and wood industries for stains and dyes
