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 thermal-neutron capture cross section and capture resonance integral for 10.7-year 85Kr have been determined in carefully monitored experiments using 99.992% isotopically pure 85Kr. Values of 1.66 ± 0.20 b and 1.8 ± 1.0 b for the thermal-neutron cross section and resonance integral, respectively, were derived from the increase in 86Kr produced during the irradiation and measured mass spectro-metrically. We conclude from our results that the burnup of radioactive 85Kr in power reactors as a possible means of disposal is not feasible.
