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 concepts of decay-width-pooled distributions and of effective number of degrees of freedom have proven helpful in the calculation of inelastic scattering cross sections and emitted particle spectra, where channels leading to the excitation of bands of levels in the continuum are open at energies low enough for the width fluctuation effects to remain sizable.
