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.

Absolute neutron-capture cross-section measurements from 0.01 to 10 eV employing a Moxon-Rae detector and conventional time-of-flight techniques are described. For the calculation of multiple-scattering and gamma-ray attenuation effects in samples, new improved methods were developed. Cross-section curves were evaluated for the elements europium and lutetium as well as for the isotopes 151Eu, 153Eu, 175Lu, and 176Lu. The cross sections could be determined to an accuracy of better than 5%; however, for some resonance cross sections the total error increases up to 10%.
