PRELIMINARY DESIGN AND SAFETY STUDIES OF LARGE RADIOISOTOPE HEAT SOURCES FOR SPACE POWER (U) VolumeⅡMISSION FACTORS AND SUPPLEMENTAL

摘要

At the present early stage of development for large isotope heat sources, the principal interest is in the determination of: those items essential to the ultimate devel opent of the heat source;basic technology to reduce the lead time upon selection of a particular mission;and technology that will be generally applicable inde pendent of the final mission. The path of this development is affected by the con siderations of safety, heat source design, re-entry protection, fuel capsule design, emergency cooling, shielding, and various mission factors as summarized herein.
