Re[2]: Japan to switch to MOX?

Correct, ie that is NOT true. Pu-239 and 241 are fissile. Pu-238 is not. I'm not
sure about the other Pu isotopes but I suspect that they are also not fissile.
Can anybody give a definitive answer?

Another statement in the full story is: "Japan had about 4.7 tonnes of
plutonium at the end of 1993, of which some 3.4 tonnes are likely to be
fissile, according to latest government figures available."

I was told that ALL isotopes of plutonium are fissile.  Is that not
true?  Al Tschaeche xat@inel.gov
