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 gamma-ray energy spectra resulting from neutron capture in 238 were calculated using the gamma-ray cascade code DUCAL for incident neutrons in the energy range 0.0 ≤ E ≤ 1.1 MeV. The overall spectral shapes generated for thermal and epithermal neutron capture agree quite favorably with an integral measurement. Absolute comparisons of the generated spectra with differential capture yield measurements exhibit general agreement. Variations in the spectral shape with neutron energy are noticeable above 3.0 MeV.
