HEAVY WATER MODERATED POWER REACTORS. Progress Report, February 1961
Construction of the Heavy Water Components Test Reac tor (HWCTR) is 58% complete. The installation of process equipment, piping, conduit, and instrumentation in the reactor building was continued. The computer code that is to be used for design snd cost computations to define optimum designs of heavy water power reactors is about 75% complete for liquid-D/sub 2/O-cooled reactors fueled with tubes of uranium metal or uranium oxide. The part of the code that is concerned with design of the reactor core was completed and is described. Measurements in the Process Development Pile (PDP) of the reactivity effects of D/ sub 2/O coolant voids in fuel assemblies of uranium metal tubes were in good sgreement with the results of earlier exponential experiments. The experimental data show that large positive reactivity effects result from coolant voids, and thereby confirm previous conclusions that boiling-D/sub 2/Ocooled power reactors fueled with assemblies of uranium metal tubes probably would not be stable.
