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 spontaneous fission neutron spectrum from 252Cf was measured using a variation of the transmission method. An excellent fit to the data was calculated assuming a Maxwellian spectrum shape with a temperature of 1.39 ± 0.04 MeV. The error includes contributions from uncertainties in cross sections and experimental statistics. In addition, all other possible sources of systematic error were investigated and found to be negligible. This value is in good agreement with earlier results at the low end of the range of measured values of the Maxwellian temperature.
