1.   Betterton recently applied for a National Science Foundation grant to determine if liquid sodium azide can be neutralized by bacteria and sunlight.

2.   In that accident, tons of volatile liquid sodium leaked from reactor equipment, but no one was hurt.

3.   In the accident, tons of caustic liquid sodium coolant leaked in what scientists called a very serious incident.

4.   It uses tins of liquid sodium, which can ignite when exposed to moisture and air.

5.   Its liquid sodium cooling system suffered numerous leaks that were potentially flammable.

6.   Liquid sodium is used as a coolant for fast-breeder nuclear reactors, which produce more plutonium than they consume.

7.   The plant, near Lyon in the center of France, has been plagued by potentially flammable leaks in its liquid sodium cooling system.

8.   With its potentially explosive liquid sodium coolant, taking apart Superphenix is a harrowing operation that will likely cost billions of dollars and take more than a decade.

9.   Without the plutonium and liquid sodium, Superphenix will be like any other reactor shell but will require several years to dismantle.

10.   A further problem is the use of liquid sodium to cool the reactor chamber.
