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.

Ex-core neutron detector and core barrel-mounted accelerometer signals were used to determine the ratio of percent variation in the ex-core signal to core barrel amplitude. Based on these data, the nominal value, including uncertainties, is 1.60 ± 0.24%/mm (0.0407 ± 0.006%/mil). This result is in agreement with both predictions, based on a one-dimensional transport model, and previously reported data.
