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 neutron capture cross section of stable 93Nb was measured by time-of-flight methodology at the Oak Ridge Linear Electron Accelerator. Individual resonances were parameterized to 7.4 keV with energy resolution ≤0.14% full-width-at-half-maximum. The average cross section was deduced from 3 to 700 keV with an accuracy estimated at 3 to 5% SD. The average data to 100 keV are well fitted by strength functions, but the fluctuations about the fit are not consistent with an energy-independent level density proportional to 2J + 1 beyond 20 keV.
