PRELIMINARY OPERATIONAL SAFETY REPORT FOR THE TASK 5.6 THERMOELECTRIC GENERATOR

The operational hazards associated with the use of a plutonium-fueled thermoelectric generator in a terrestrial satellite are evaluated. It appears that the plutonium fuel can be consumed and dispersed at high altitude during reentry, following a successful mission. As an alternative, however, since the fuel (Pu/sup 238/) is an alpha emitter with a long half life, it appears that random intant recntry following a suceessful mission is feasible. As a precaution against aborted missions, the launch azimuth should be over water as much as possible to avoid impact or dispersion in areas of signifieant population density. It is recommended that the fuel and generators be transported by air carrier to preclude local restrictions of ground transport and to provide better statistical safety. The transport phase poses a very minor safety problem. (auth
