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.

Thermal-neutron spectrum indexes in uranium and uranium-plutonium clustered fuel elements, organic-cooled and D2O-moderated, were measured in the temperature range from 20 to 200°C, by activation of 239Pu-235U and 176Lu-164Dy detector pairs. The experimental results were used to test the multigroup transport code HEROIC and associated cross-section libraries.
