THORIUM OXIDE SLURRY FILTRATION: PRELIMINARY TESTS OF A 3-MICRON POROLOY SINTERED FILTER RUNS 11, 12 AND 13 IN LOOP L-4-24S

PDF Version Also Available for Download.

Description

A Poroloy sintered-metal filter unit which was placed in a bpass arrangement in a 5-gpm loop, L-4-24S, for runs 11 and 12 was used to separate water from a flowing stream of thoria slurry. During runs ll and l2, the filter unit prevented the accumulation of thoria in the horizontal pressurizer during 490 hr of operation at temperatures up to 250 deg C and circulating stream concentrations up to 490 g Th/kg H/sub 2/0. Run 13 was made with the main stream of the loop flowing through the center of the filter. The flow velocity through the center of the ... continued below

Description

A Poroloy sintered-metal filter unit which was placed in a bpass arrangement in a 5-gpm loop, L-4-24S, for runs 11 and 12 was used to separate water from a flowing stream of thoria slurry. During runs ll and l2, the filter unit prevented the accumulation of thoria in the horizontal pressurizer during 490 hr of operation at temperatures up to 250 deg C and circulating stream concentrations up to 490 g Th/kg H/sub 2/0. Run 13 was made with the main stream of the loop flowing through the center of the filter. The flow velocity through the center of the filter was sufficiently high to prevent a filter cake from building up, and consequently, the filter unit was rendered ineffective. Microscopic examination of the filter screen revealed no other reason for the ineffectiveness of the filter in run 13 other than the lack of filter cake. Further testing with and without cake buildup is scheduled for work in the pump test stand and in L-4-24S. (auth)
