I. Plant Development and Expansion
4. Project CG-734 - RMC Button Line
Arrangements were made during the month to speed detailed design on
the equipment to be provided under this project. A revised project
proposal requesting authorization of construction funds is scheduled
for submission to the Atomic Energy Commission by month-end.
5. Proi ect CG-756 - Z Plant Filter Replacement
Design of equipment which is provided as a part of this project was
started on July 15. Three filters have been ordered from the
Cambridge Company for testing and are expected by August 17. Orders
will be placed for replacement filters at the rate of about 100 der
month after satisfactory completion of efficiency tests.
6. rect CG-613 - U Exansion
The installation of the feed box calrods has been completed. The
capacitance type bin level indicators are being installed in the
cyclones and bag filters.
Some of the 2J piping in the powder unloading system has been found
to be undersized and must be replaced with 3" pipe. This work is
scheduled to be performed August 1, 1957, by Construction Operations
through a sub-contract to a Fix Price Contractor because of the
Test wet filters for the calciner off-gas lines have been installed
in H Cell to determine their effectiveness in removing uranium
solids from the calciner off-gas system. Preliminary tests appear
Several modifications are being performed on the K Cell calciner to
test the effect of these changes on the efficiency of calciner
operation. The modifications include: Bumper rings on the agitator
paddles to prevent interference of feed points and thermohm wells
with the paddles, relocation of the thermohm wells out of the calciner
agitator paddle orbit, reduction of the length of the agitators paddles
to increase the clearance between the paddles and the feed points,
installation of thermocouples to check the efficiency of calciner
agitation and feed temperature control, installation of baffles in
the calciner cover to reduce powder carried into the calciner feed
7. Project CG-712 - Reduction Qf Air Borne Noxious Fumes
The tie-in of the absorber jet discharge line to the new 80' stack
is scheduled for August 1, 1957. The blower for the high stack is
scheduled on site about August 15, 1957.
