As a result, it is likely that curium will be excluded from most MOX fuels.
MOX fuel containing thorium and plutonium oxides has also been studied.
The reactor grade plutonium is being processed into MOX fuel.
The mixture is not sufficiently enriched for efficient nuclear weapons, but can be used once as MOX fuel.
MOX fuel has been in use since the 1980s and is widely used in Europe.
Both reactors are certified for the use of MOX fuel.
These reactors can load approximately 20-50% of their cores with the MOX fuel.
It exposed a poor safety culture and an inadequate secondary control procedure in the manufacture of MOX fuel.
The new guidelines appear to be designed specifically to accommodate the air transport of MOX fuel.
To this the Commission says: we want to process it into MOX fuel.
