This letter report describes the activity under Task
Order No. C during June, 1958?
During this period, four runs were made in the small
experimental generator. These included two 1/10-scale runs, which
completed the 1/10-scale temperature-dependence tests, and two 1/5-
scale runs, to explore the scale factor.
1/10-Scale Runs
Data for the two 1/10-scale runs (Nos. 14 and 15), are
presented in Table 1.
These two runs were made with the generator unit partially
immersed in a tank containing about 1,100 gallons of water, in order
to study heat losses under simulated-field generation conditions.
As previously noted, the water surrounding the generator unit
exerts a noticeable cooling effect.
The catalyst concentration was selected in these runs to
give reaction times well under 1 hour. The data at 47 and 65
degrees F from Runs 11, 13, 14, and 15 were then plotted to show
the variation of catalyst weight with temperature for total
generation times of 34 to 42 minutes in 1/10-scale tests.

1/5-Scale Runs C~~F~
~FNTI
At
One 1/5-scale run at 66 F served to check the Scaling
effect on the new temperature versus catalyst plot. Run 16, described
in Table 2, closely approximated the conditions of Run 15 in Table 1,
except that Run 16 used double the amount of reagents. Because in
the larger scale tests the generator is less efficiently cooled by
the surrounding pool, it was expected that the 1/5-scale rua would
be faster than the 1/10-scale runs.
The results of Run 16 bore out the expectation. The total
generation time was reduced to 23 minutes, and the temperature rise
was higher (in the shorter time). These results will be used as
a basis for scaling up the catalyst requirements for the full-scale-
generator tests.
In Run 17 (Table 2), almost twice the weight of catalyst
was added as would have been needed for approximately a 30-minute
generation time. The generation was so rapid in this run that the
time, reported as 8 minutes, was only approximate. Although the
use of a high catalyst concentration reflected an experimental
error, Run 17 showed that controlled reactions can be accomplished
in very short times, if the equipment is designed to handle high
rates of gas evolution, and if the extra amount of catalyst needed
is within the total-weight limitation.
During July, preparations for full-scale gas generation
will be made. These tests will take place at a private lake. It

is planned that a 1/10-scale experiment will be run at this site
before the two full-scale experiments are performed. This 1/10-
scale test is expected to reveal any radical differences between
the lake water and the water used in all of the other
small-generator tests.
The total appropriation on this Task Order was $44,143.
As of July 1, 1958, the unexpended balance was approximately $4,700.
