ok I can confirm what I posted about earlier. one of the reactors does indeed have MOX rods and it is indeed number 3...and 9 feet of them were exposed(a rod is 12-14 feet)
But the BBC’s Chris Hogg in Tokyo says the second reactor is a different type which uses MOX (plutonium plus uranium) fuel and the consequences of a problem there are potentially more severe.
Quoted by Kyodo, Tepco said the tops of the MOX fuel rods were 3m above water.

on a side noye why would Japan have MOX rods in the first place? They are used to make nuclear weapons
Plutonium is blended with uranium as a way to get rid of weapons grade plutonium such that it does not have to be disposed of as nuclear waste.
There are 10 plants I Japan that are authorized to use MOX but I think only 7 do.
