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.

Resonance parameters, particularly the radiative width of the 292.36-eV s-wave level in 91Zr + n, have been reinvestigated. The spin assignment J = 2+ is supported. The neutron width Γn = (866 ± 11) meV and radiative width Γγ = (86.8 ± 2.2) meV indicate less neutron capture than do parameters derived from earlier studies. This lower capture, however, is more compatible with integral measurements and a lead slowing down spectrometer measurement.
