Mechanical design issues associated with mounting, maintenance, and handling of an ITER divertor

Description: Several designs that address plasma-facing plate configurations and thermal-hydraulic design issues have been developed for the ITER divertor. Design criteria growing out of physics requirements, physical constraints, and remote handling requirements impose severe mechanical requirements on the support structure and its attachments. These pose a challenge to the mechanical design of a divertor, which must be addressed before a functional divertor is practical -- that is, one that can be remotel… more

Automated array assembly. Quarterly report No. 5. [Cost analysis and factory design]

Description: During this quarter, an interim 1982 factory was designed for the large-scale production of silicon solar cell array modules. The boundary conditions for this design are the use of Czochralski silicon crystals and $25/kg polycrystalline silicon. The objective is a large-scale production facility to meet an intermediate ERDA cost goal of $2.00/W in 1982. The approach was to first consider a panel design which could be expected to have a 20-year life and would also meet the JPL specification on m… more

Silicon dendritic web material process development. First quarterly report, March 28-June 30, 1980

Description: Initial values of pressure, power, and speed have been determined for seam bonding interconnects to dendritic web solar cells. Satisfactory bond strengths and high yield have been achieved without cell damage.

Fuel cell applied research: electrocatalysis and materials. Quarterly report, October 1-December 31, 1978. [Supported platinum cathode catalysts in phosphoric acid fuel cells]

Description: Investigations were carried out on the sintering of carbon supported platinum catalysts in phosphoric acid at 150/sup 0/C over a 3500-hour period. The most significant result was that the sintering rate was five times slower for these electrodes as compared with unsupported platinum electrodes. After aging the electrodes for 1200 h, attempts were made to regenerate the active areas of one of the electrodes by cycling at 100 V/s in various voltage envelopes between -0.1 V and 1.1 V. These treatm… more

High-temperature fuel cell research and development. Final technical status report, June 1977-September 1978

Description: An initial survey of the literature produced a list of ceramic materials with properties which made them potential candidates for use in molten-carbonate fuel cell tiles or electrodes. Seven of the materials in the original list were dropped from consideration because of unfavorable thermodynamic properties; four materials were set aside because of high cost, lack of availability, or fabrication difficulties. Thirteen compositions were tested statically at 1000 K in a Li/sub 2/CO/sub 3/-K/sub 2… more
