This letter report describes the activity under Task
Order Na. C during February, 1958.
During this period, three 1/5-scale runs were made in
the small experimental generator. The results are indicated in
Table 1.
In all three runs, the time for total generation was
in excess of the specified maximum of 60 minutes. On the basis
of the results obtained from the eight tests conducted thus far
in the small generator unit, it is necessary to revise the
relationship among catalyst concentration, initial temperature,
and time for total generation that had been deduced previously
from the small-scale laboratory studies of this system. The
data are currently being analyzed to determine the relationship
which best expresses the influence of catalyst concentration
and temperature on generation time.
The 1/5-scale experimental generator is being modified
to incorporate some of the design changes that are contemplated
for .the full-scale experimental unit. These modifications
include the use of neoprene-coated nylon fabric tubing for the
generator water inlet and the catalyst feed-tube inlet so as to
eliminate the zippers, which have proven unsatisfactory in the
1/5-scale unit.

-3- March 1~, 1958
CONFIDENTIAL
Future tests in the small generator will be run using
the procedure that is expected to be followed in the full-size
generator, as related to the addition of the sodium borohydride
and of the cobalt chloride, and to the tie off of the inlet tubes
during the generation period.
The full-scale experimental unit has been ordered.
Delivery is expected by about June 1, 1958?
The total appropriation on this Task Order was X39,375.
As of March 1, 1958, the unexpended balance was approximately
$8,350.
