New coolants, new fuels: A new generation of university reactors
Here’s an easy way to make aging U.S. power reactors look relatively youthful: Compare them (average age: 43) with the nation’s university research reactors. The 25 operating today have been licensed for an average of about 58 years.

Fabrication and welding methods used to make 217-rod grid spacers for liquid-metal fast breeder reactor application have been developed. Grid straps are formed from cold-worked Type 316 stainless-steel strip material and are assembled into a hexagonalshaped honeycomb grid, using resistance welding. A support strap is then welded onto the periphery of the grid using a manual gas tungsten arc welding (GTAW) process. The grids (11) are then located and appropriately spaced inside a hexagonal duct and attached using an automatic GTAW process. Three of these subassemblies have been completed and are awaiting loading of the fuel rods. After loading, the subassemblies are to be inserted in driver positions of the Fast Flux Test Facility for the acceptance test phase.
