We don’t allow radioactive equipment to pass into the plant unless its fuel assemblies. And all I've been told is that cobalt-60 was the main contaminant; others are probably there, but not in large enough amounts to really make a difference.

UconnMaterials,
I had been told before (obviously this was wrong) that cobalt-60 was mainly formed from cobalt-58, upon further research and your guidance I realize that the majority of the contamination must have come from either contaminated scrap SS, or tramp cobalt-59 to cobalt-60 from the...
all parts are checked for any count when it comes to us so we know what comes in and what goes out...just a procedure to keep radioactive material from getting out. The part originally checked out with no count.

Again, I'm an intern...I don’t have access to toys like that (though i wish i did). The source of the radiation is a Nuclear Reactor...so I’m Guessing mainly U-235 and a small amount of plutonium-239 (<3%) If I'm not mistaken, I believe that Cobalt-60 can be formed when Cobalt-59 is bombarded...
btrueblood is right, cavitation shows up in the 0 to 1x range. And with water, cavitation always occurs slightly unless the NPSHa is ten times or more than the NPSHr. One must note that cavitation causes the most damage at 2x NPSHr, and slightly less, say 1.5x, will cause enough cavitation that...
seems like a splendid idea to me. Centrifugal pumps dont seem very efficient at high head, but are awesome for high flow...as where displacement pumps are awesome for high head, but relativily bad at flow for their size... With this setup it seems like, since ur getting a low flow to begin with...
I am new here [morning], and i'm an engineering intern, not a real engineer...but i'm trying to find out if there is any way that an oil-filled capacitor with a stainless steel case can become contaminated with cobalt-58 or 60. I was told that when heated the metal becomes pourous and absorbs...
