processing pliant in order to purify it and make it a better es a cooling water, and this is run through th QO ronctor and I would Jitse to male one very clicar distinction h ore between the kinds of isotonss that we have been talking about un to nov and tho kings of isotopes that we get enti of this far sida of the veactor, We have been talking mainly in torms of fis h and preducts, the results of splitting uraniva atoms and axtes they are senarated from the waste how they may get ba eck into environmnonis. IZ you exnlose an atenic bemb, this may con an area from fission products, too. The frol elenenats in the reactor here arc completely isolated frou tho water. uranium out of those fiugl elements, no fish and produ the cooling water which is merely going by and keevins cool. The kinds of radio isotoxes which we get result fron minerals which are present in- the water, to begin wit a, end as these minerals go through the pllc, thoy are bomba rded by the neutrons and becen> radioactive because of the ne utron activation, This is the same sort of a process as Dr I suspect, would have at the Oak Ridge whera thoy are some sort of isotone -- taking sone material, putting pils, radiating it for a time and pulling it out, and materials in this mannor. As the material comos out, it contains
