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.

The thermal-neutron flux produced by a 252Cf spontaneous fission neutron source was computed for various spherical assemblies with moderators of iron, aluminum, carbon, D2O, beryllium, and H2O and reflectors of H2O and carbon. Consideration of spherical assemblies with a 252Cf source located at the center and at various distances from the center lead to a configuration, adaptable to neutron radiography, that has a small thermalization factor and a flat thermal-neutron flux.
