Quiz: RE(2): Power Plant was declared bankrupt.
Jaro,
>>>>>>>>>> the quantity of Pu from a small
350 MW breeder reactor would not be anywhere near
"hundreds of tons." Such large quantities would
be more typical of the combined stocks of a large
national nuclear program with at least a dozen
large reactors. Also, until the spent fuel is
reprocessed, it remains extremely radioactive,
providing a high degree of self-protection
against theft.

>>>
I agree with the "self protection" factor to a
some degree. I wish that it was the case...
However, let me ask you.
1. What will be dose rates from the U-238=>Pu-239
blanket?
My guess because U-238 is not a thermal neutron
U-235 fuel or MOX where majority dose coming from
the fission products. U-238 is there NOT to
support fission, as you obviously are knowing and
it will not produce as much of the fission
products into the blankets as from U-235 thermal
neutron fission. We may see high dose rates from
the material activation which will go down fast
12 month or so. I would guesstimate, after
several month we wont see any acute gamma dose
rates to have an efficient "self protection
factor", unless millirems are killers and thieves
are antinukes ;-)
2. U-238/Pu-239 are very heavy metals = hundreds
of tons is not a such huge amount to see it as a
stock pile as one may think at first.
As the Quiz's question:
Question: For how many years and how many of
thermal-Neutron " donor " reactors were working
out to make up the first Pu-239 fuel load for the
BN-350?
A nice weekend for the everyone.
Emil.
