Title: SNAP RADIOISOTOPE SPACE PROGRAMS TASK 7. Quarterly Progress Report No. 7, April 1 through June 30, 1961

Abstract

Safety analyses of the launch of SNAP-type units as to launch, ascent, and intermediate or final-stage failures are reported. A preliminary design study to define the configuration and performance of the Surveyor generator is completed. Dispersion patterns are found for radioactive materials released by the high-velocity vertical impact of Surveyor-type generators on the moon. High- velocity testing methods are discussed. Flare and telemetry capsules, designed to simulate fuel cores of nuclear auxiliary power systems in Atlas-type ballistic re-entry trajectories, are in final production stages. The design of a SNAP-3 test generator is completed. Analytical studies are reported on the diffusivity of various particle sizes and on the ablation phenomenon as it pertains to re- entry of radioisotope fuels. A preliminary flare and telemetry capsule test is discussed. Routine coding, assembly, and checkout operations are carried out on radioisotope shielding codes. Arrangements are made to obtain code input information and actual radiation levels from the Sr/sup 90/-fueled weather station generator, as a check problem to verify code calculation results.
