1.   Development costs could be reduced by expanding these existing nuclear sites which are currently used primarily to produce fuel for military purposes.

2.   However, environmentalists argue that the costs of producing the fuel must also be taken into account.

3.   And in the north near Khudjand, uranium mines supplied a secret complex whose cascades of machinery produced nuclear fuel for Soviet power plants and bombs.

4.   As a result, refiners have delayed producing the fuel.

5.   Aside from being useful for human life support, lunar water could be divided into hydrogen and oxygen to produce rocket fuel.

6.   As it turned out, none of the plants they brought back was useful in producing diesel fuel.

7.   At least two refiners said they would produce more fuel than they planned.

8.   Bitor currently has one plant producing the fuel.

9.   A breeder reactor, a type intended to produce more fuel than it consumes, needs the richer form of uranium.
