Title: MEASUREMENT OF THE TEMPERATURE DEPENDENCE OF K(infinity) FOR A 233 UO2 -ThO2 HTGR LATTICE.
Abstract: The second in a series of experiments using the High Temperature Lattice Test Reactor has been completed and provides information on the temperature dependence of k for 00 a 233 UO 2 -232 ThO _ C fuel mixture. 2 The infinite medium multiplication factor, was found to decrease by ,0350 ± .0015from 20 0 C to 1000oC.This result provides direct information necessary in the design of the control system and in the safety analysis for advanced High-Temperature Gas-Cooled reactors.v Many people have contributed to the successful completion of this experiment.In particular, many helpful discussions with
