in the 233-S Bldg. rather than attempt the seal installation
on the installed pump in its present position. Attempts will
then be made to salvage the removed pump by installing the
second mechanical seal. This will then provide a spare unit
for this position.
With the concurrence of the Redox Technology Operation plans
have been made to fill the 107-SX tank (currently Redox salt
waste receiving tank) to a level of 22 feet before re-routing.
At this time the air-lift circulators are to be turned off and
the 107-SI tank will be used as a test tank for evaluating both
bumping and sludge temperature effects. Maximum fill limits
for other waste storage tanks will then be established on the
basis of data obtained from this test.
Instrumentation at the SX tank farm has been very erratic since
installation, and unplugging of the dip tubes has been very
difficult and at times impossible as no bleed-off for flushing
was provided when the installation was made. Work was therefore
started this month on the installation of a test bleed-off
system at the 107-SX tank, which it is felt will make possible
unplugging of the lines.
Improvements started this month in the women rest and lunch
rooms to bring these quarters above standard, include replacing
the outmoded stove, installation of a separate ventilation
exhaust system with increased flow, and minor convenience
features such as vanity benches and shelves. The tile floor
and planned wall redecoration will give these rooms an attractive,
3. Inventions or Discoveries
There were no inventions or discoveries of a patentable nature
reported in the Redox Operation during the month of July, 1957.
G. Events Influencing Costs
The increased production quota for the Redox Operation during the
month of July will result in a significant drop in unit costs for
the facility as compared to previous month cost figures.
An SAR was issued this month to provide for the reduction of
$34,777 worth of spare electrical assemblies over the next nine
months. After the stock has been depleted, the source of spares
will be from a stock of component parts which were set up abou
two years ago. In addition to this, $4,900 worth of obsolete
charging yokes, pump and agitator parts were removed from inventory
Experience has proved that the resultant savings from the install-
ation of the isolation valves to the panel board gang valves in
the 202-S Building may be much greater than originally anticipated.
Prompt repair service is now possible to the gang valves because
