Diffusion in polycrystalline Y/sub 2/O/sub 3/ and Er/sub 2/O/sub 3/

Description: A tracer sectioning technique was employed to measure cation self-diffusion coefficients in fully dense polycrystalline materials under oxidizing conditions. Results are D = 1.65x10/sup -2/ exp(-69,200/RT) cm/sup 2//s for Y/sub 2/O/sub 3/ (1400 to 1670/sup 0/C), and D = 1.48 exp(-102,200/RT) cm/sup 2//s for Er/sub 2/O/sub 3/ (1400 to 1700/sup 0/C). The greater activation energy for erbium diffusion in erbia is attributed to a mass effect. Oxygen diffusion coefficients were extracted from observ… more

Project CLEER: A study of the heat transfer characteristics of a capillary wetted surface

Description: An experimental program (Project Cleer) was initiated to investigate the heat transfer characteristics of a surface covered with a wick-like material and cooled by a capillary liquid. The preliminary heat transfer analyses developed and the measuring equipment and methods to be used are discussed. (LCL)

Review of literature on catalytic recombination of hydrogen--oxygen. [Removal of hydrogen from containment atmosphere following LWR blowdown]

Description: The results are reported of a literature search for information concerning the heterogeneous, gas phase, catalytic hydrogen-oxygen recombination. Laboratory scale experiments to test the performance of specific metal oxide catalysts under conditions simulating the atmosphere within a nuclear reactor containment vessel following a loss-of-coolant blowdown accident are suggested.

External-Fuel Thermionic Reactors

Description: The concept of the external-fuel thermionic converter, in which the fuel surrounds an inner emitter annulus, is introduced and the major advantages of its use in a thermionic reactor are discussed. In-core reactors, ranging from 15-ekW to megawatts, can be designed based on external-fuel converter modules of fixed emitter and collector dimensions. Sizes and weights of typical reactors in this power range are shown.
