Fuel Cycle Programs, Quarterly Progress Report: January-March 1982

A method of making anhydrous aluminium chloride from aluminium hydroxide or water-soluble Al/sub 2/O/sub 3/ by solvent extraction and low-temperature chlorination is being developed. Analytical methods for measuring leaching from simulated waste forms are being studied. Logging techniques are being developed to measure the relative amount of residual oil in a depleted oil reservoir by injecting gamma-active solution into it. Work is in progress to test the behavior of radionuclides leached from proposed nuclear waste repositories, using laboratory analog experiments. The /sup 13/C//sup 12/C ratio of oil in a core of granite from northern Illinois drill hole UPH-3 is about the same as for average petroleum. Testing and development of equipment for the destructive analysis of full-length irradiated fuel rods from the Light Water Breeder Reactor are in progress.
