One question was rained concering the development of pumping equipment.
Apparently the only problem different from the development of pumpsfor
. conventional chemical rockets is that the pump mustbe able to work near the
reactorin the presence of some radiation,
‘The second question came up on the difference in rockets and aircra{t

rocket is short-livei and uses hydrogen only whereas the aircraft must use air,

It was discussed how soon this reactor or a similar type might be applicable
to an actual rocket, It was stated that NASA and AEC would probably await
