Aerospace nuclear safety report for August 1967

Description: The AEC Safety Branch advised that the present outlook for a potential mission using four modified SNAP-3 type generators is rather negative. Drop tests of four SNAP-19 intact reentry heat source capsules were conducted at the Tonopah Test Range. A preliminary GE SNAP-27 safety analysis was reviewed. Three arc tunnel tests were conducted at low heat fluxes. Debris were collected on downrange impactors from all tests. The rapid helium depressurization test on fuel microspheres was conducted by B… more

Fast Neutron Medical Research Facility-Dosimetry

Description: Dosimetry measurements and calibrations have been made at the University of Washington's Fast Neutron Medical Research Facility. The facility is designed to deliver localized neutron doses of a few rads to the testes of volunteer subjects at 2.5 MeV and 14 MeV. Dose measurements were based on the use of tissue equivalent ion chambers. Dosimetry and shielding measurements show that doses accurate to +-10% can be delivered to the volume of interest while maintaining safe dose levels outside the s… more

MFC study - krypton and xenon recovery

Description: As commercial fuels reprocessing develops, large quantities of radioactive and stable fission rare gases will become available. These gases pose both a problem and an opportunity. When efficient methods of control and recovery are developed, the cost of these materials will be greatly reduced. With increased availability and reduced costs, commercial and government applications would be accelerated. Thus the fission gases which present potential environmental problems, would become useful by-pr… more

Consequences of Internal Heat Flow in Radioisotope Heat Sources.

Description: Equations relating the maximum internal temperatures of various-shaped fuel forms and other source parameters are given. By using calculated results, the use of cermets is compared with the use of oxide-metal laminar structures as methods of decreasing the resistance to heat flow in the interior of heat sources and achieving higher surface heat fluxes without exceeding maximum allowable internal temperatures. The laminar composite fuel form is moderately superior. The expected vapor phase migra… more
