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.

Yields and spectra of neutrons produced in the bombardment of light nuclei by deuterons of energies up to 20 MeV were measured in order to investigate the usefulness of the reactions as high-intensity neutron sources. Neutrons emitted at angles up to 32 deg were studied for thin targets of deuterium and beryllium, and for thick targets of lithium, beryllium, and carbon.
