First, plutonium oxide
could be mixed with uranium and used to fuel commercial nuclear reactors.
This time it was plutonium oxide
. All nuclear waste is dangerous - but this stuff is the daddy of them all.
Environmental groups and Governments of countries the shipment passed feared the mixed uranium and plutonium oxide
(mox) fuel could prove a target for terrorists.
The report found there was a 'lack of safety culture' at Sellafield and revealed there had been widespread falsification of safety data on mixed uranium and plutonium oxide
(MOX) fuel delivered to Japan's Kansai Electric.
In a worst-case disaster, NASA estimated that 5 billion people would have received "99% or more of the radiation exposure" from 400,000 curies of plutonium oxide
released into the atmosphere.
The waste-irradiated fuel produced would however, contrary to suggestions in the article, be far more difficult to handle and to dispose of than the existing cans of plutonium oxide
At the Rokkasho plant, technical measures have been taken to produce mixed uranium and plutonium oxide
fuel so as not to accumulate plutonium, according to the statement.
It covers the receipt of plutonium oxide
and uranium oxide, the manufacture of MOX fuel elements for Light Water Reactors (thermal MOX fuel) and all associated support services.
The report found there was a "lack of safety culture" at Sellafield and revealed there had been widespread falsification of safety data on mixed uranium and plutonium oxide
fuel delivered to Japan's Kansai Electric.
At the start of the process, plutonium oxide
powder in 7kg cans is mixed with an equal amount of uranium oxide and converted to metal in an electro-reduction unit.
A study for the National Nuclear Security Administration (NNSA) on the feasibility of providing up to one metric ton of plutonium oxide
per year using H Canyon and HB Line for the Mixed Oxide Fuel Fabrication Facility (MOX) recently was completed and received approval from the NNSA administrator.
