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.

A semiempirical formula for the gamma-ray albedo of alternating layers is proposed. The values of the albedo calculated by this formula agree with the experimental ones for alternating layers of tin-aluminum and lead-aluminum slabs within ∼10%, except for the case of very thin alternating layers. This formula was applied to the angular distribution of photons backscattered by the alternating layers and the difference between experimental and calculated values was < 18%.
