- The U.S.-Japan Collaboration on Breeder Fuel Reprocessing: ORNL's Role. In March 1986 the United States and Japan agreed to collaborate on developing and demonstrating breeder-reactor fuel reprocessing at a Japanese fuel-recycling pilot plant, which incorporates technology developed at ORNL. The U.S. work, mostly in remote technology, is centered at ORNL.
- National Laboratories and Science Education: The University Relations Programs at ORNL. ORNL and other national laboratories play a significant role in the education and training of university students and providing unique research experiences for university faculty. To improve science education and encourage more U.S. students to choose technical careers, ORNL has developed new programs for undergraduate and precollege education.

When news of the Chernobyl nuclear accident was first announced in April 1986, ORNL scientists made calculations to determine about when the accident had occurred. Other ORNL scientists helped model the accident and used information on fission-product concentrations in Europe to determine the chemical conditions affecting the two releases of radioactivity from the stricken reactor. Since then, ORNL scientists have been analyzing environmental radiation data from Europe and the Soviet Union.

- State of the Laboratory- 1984: Exploring New Areas. In this updated report based on his February 5, 1985, address to the staff. Postma notes that the Laboratory's return on some investments has been remarkable. Seed money projects have brought about $4 in research funds to ORNL for every $1 invested by the internal Exploratory Studies Program. ORNL research also has helped others save money. For example, Laboratory recommendations on energy options have helped Liberia save up to $20 million annually. ORNL studies of the potential thermal shock problem of commercial nuclear reactors saved electric utilities millions of dollars.
- Crickets and Coal Liquefaction Research. Several years ago cricket eggs exposed to a chemical under study in the synthetic fuels program hatched crickets with assorted abnormalities such as an extra eye, antenna, or head. The author tells how ORNL toxicologists and analytical chemists determined that certain trace substances cause these teratogenic effects and how they eventually identified a teratogenic compound in these substances.
- Shedding Light on Molecules and Atoms: Photoelectron Spectroscopy Using Synchrotron Radiation. ORNL researchers using the magic source of synchrotron radiation have helped to usher in a new era of photoelectron spectroscopy called photoelectron dynamics. Recently, use of this method has provided fresh answers to a number of fundamental questions on the electronic structure of small molecules and metal vapors.

- Shooting for Fusion Energy Breakeven: Pellet Fueling Research at ORNL. ORNL scientists have developed a gun and a centrifuge accelerator to "shoot" frozen pellets of hydrogen fuel into tokamak fusion plasmas. One ORNL injector helped MIT exceed the Lawson criterion, another achieved steady-state plasma fueling, and an improved version of ORNL technology should help a Princeton tokamak's energy output equal the energy input.
