was made by Dr. Schreiber from Loa Alamosa on Rover,
has approximately a 14-year history of cevelopment, and the reason it 16
being used right now je that it hae a better specific impulse than the chemical
type.
Some more ‘advanced types using tungeten or carbide are the only one .
which approach the efficiency of graphite, but these are not anywhere near
ready to be applied,
The performance figures submitted by Dr. Schreiber
on what can be done with the graphite type reactor are attached, These
performance figures he yave out are ny stern studies and they should be used
- with caution, and the question, of course, remains whether this type reactor
"can be increased to say 400,000 to 700,000 Ibs, thrust.
One possible application of the Rover type reactor would be for a 3rd
stage on Saturn,
This may be highly preferable to the present planned
chemical 3rd and 4th stages.
Kiwi-A cannot lift its owr.
weight but during the experiment they attempted
_to duplicate the temperature conditions and to deliver 70 megawatts of power
