Conclusions • Nuclear power is the most practical alternative for extraterrestrial basing from the standpoint of logistics and resource utilization. • Base power needs can be met initially with SP-100 class units followed by subsequent introduction of larger NDR units to: minimize logistic burdens; reduce lunar siting requirements; and enhance base capabilities. • The proposed larger units are preferable in terms of meeting lunar base power demand growth requirements and system reliability requirements. • The later, larger units should be based on the NDR technology that is adaptable to multiple applications in order to conserve national resources while meeting diverse needs.
