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.

Received November 3, 1981 Accepted for Publication March 22, 1982 A symbiotic system of Pu-Th- and 233U-U-fueled reactors has been proposed and analyzed. The Pu-Th reactors utilize a tight lattice core and the 233U-U reactors utilize a regular pressurized water reactor (PWR) core. The two cases were investigated with different Pu-Th cores (system A: VM/VF =0.4 and system B: VM/VF - 1.0) and similar 233U-U cores. The cumulative 30-yr requirements of uranium ore and separative work for both systems were evaluated and indicated significant savings compared to current PWRs with plutonium recycle and the cross-progeny fuel cycle. The fuel cycle costs calculated for the proposed systems were slightly higher than those for the current PWR cycle.
