Monthly report of activities: MAY 1, 1969

Some of the activities this month are: (1) The AEC authorization bill was passed by the House of Representatives on April 4 and by the Senate on April 8. It has been signed by the President. The 200 BeV accelerator is authorized for construction in fiscal year 1969, with a total authorization of $32.333 million. The appropriation bill is in the House at the time of this report. (2) A tentative decision has been made to incorporate an injection storage ring into the accelerator design. This ring, if built, will have the radius of the main synchrotron and will be mounted on the wall of the main-ring enclosure. In order to avoid confusion with the CERN ISR, we have decided to call our device the accumulator. Protons will be injected into the accumulator from the booster at 10 GeV kinetic energy. Thirteen bunches will be stored during the 2.6-second cycle. They will then be extracted from the accumulator in one turn and injected into the main ring. The principal advantage of the accumulator is that the booster works continuously rather than in short bursts. The repetition rate of the booster will therefore be reduced from 15 Hz to 5 Hz. …

Diffusion in polycrystalline Y/sub 2/O/sub 3/ and Er/sub 2/O/sub 3/ (open access)

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

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 observations in the reoxidation of small single crystals of uniformly reduced oxides produced by vacuum fusion. The oxidation process proceeded by the development of a fully oxidized external shell, the growth of which was rate-limited by diffusion of interstitially dissolved oxygen through the oxidized layer to a sharp interface with the reduced material. The growth of the oxidized shell was followed by means of a thermobalance. Oxygen diffusion coefficients were calculated to be D = 6.01x10/sup -6/ exp(-19,600/RT) cm/sup 2//s for Y/sub 2/O/sub 3/ (1064 to 1276/sup 0/C), and by D = 4.76x10/sup -5/ exp(-30,100/RT) cm/sup 2//s for Er/sub 2/O/sub 3/ (1060 to 1292/sup 0/C).

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

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] (open access)

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

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 (open access)

External-Fuel Thermionic Reactors

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.

Nuclear Safety Program (open access)

Nuclear Safety Program

While the safety status of the Richland facilities has in the past been deemed adequate all aspects of nuclear technology have progressed and evolved including standards of nuclear safety. During FY 1968 the nuclear safety R&D efforts continued along the lines and at about the schedule predicted at the beginning of the year. Hence, the safety problems to be studied have been identified and the program seems well-defined. While some program modifications and changes in emphasis are to be expected, the five-year outline shown here is considered to be a reasonable representation of the safety work of highest priority to be studied.
