21.   The Russians are taking that money and using it to produce plutonium.

22.   They plan to build breeder reactors, ingenious devices that generate energy and produce plutonium.

23.   This produces plutonium that can be re-used in power plants or used in bombs.

24.   To advocates, the beauty of breeder reactors was that they produced more plutonium than they burned.

25.   U.S. intelligence officials believe North Korea has used its existing nuclear program to produce enough plutonium to make one or two nuclear bombs.

26.   Under the Clinton plan, eight tons of the plutonium were to be ruined by mixing it with the waste created when the plutonium was produced.

27.   While the Europeans are producing plutonium, they have canceled many of their breeder reactor plans.

28.   Pakistan has declared that it stopped producing highly enriched uranium but it may be acquiring the capabilities to produce plutonium, the study said.

29.   Plans included buying reactors from Russia and building several fast-breeder reactors which use plutonium as fuel and produce more plutonium than it consumes.

30.   A fast-breeder produces additional plutonium for fuel while generating electricity.
