1.   One is that they use the oldest and most energy-intensive technology to enrich uranium, gaseous diffusion.

2.   The gaseous diffusion process that it used to enrich uranium yields a lot of residual nickel, which has a high value on the scrap-metal market.

3.   The third gaseous diffusion plant is at Oak Ridge, Tenn.

4.   The technology used at both plants, gaseous diffusion, was developed during World War II, to make the bomb that destroyed Hiroshima.

5.   Richardson said he was committed to addressing the health and environmental concerns involving both the gaseous diffusion plants and worker exposure to beryllium.

6.   The plant uses gaseous diffusion to enrich uranium for use as fuel in nuclear reactors.

7.   The two gaseous diffusion plants blend uranium into the concentrations needed by power plants.

8.   Workers at the three gaseous diffusion plants will be eligible for compensation if they have primary lung or bone cancer or another specific cancer specified by Congress.
