The symposium featured a range of briefings from R. F., U. S., and in­ternational experts on policy, science, and engineering issues relevant to the conversion of research reactors from HEU fuel to LEU fuel. These briefings were organized into several sessions, reflected in the four chapters of this report: [25]

• Chapter 3 addresses the challenges and successes associated with converting eight specific U. S. and Russian reactors; and

• Chapter 4 addresses future research directions and opportunities, including opportunities for further interaction between the U. S. and Russia on research reactor conversion.
