Abstract : This report describes models for multimegawatt, space power systems which Sandia's Advanced Power Systems Division has constructed to help evaluate space power systems for SDI's Space Power Office. Five system models and models for associated components are presented for both open (power system waste products are exhausted into space) and closed (no waste products) systems: (1) Open, burst mode, hydrogen cooled nuclear reactor turbo alternator system; (2) Open, hydrogen and oxygen combustion turbo alternator system; (3) Closed, nuclear reactor powered Brayton cycle system; (4) Closed, liquid metal Rankine cycle system; and (5). Closed, in-core, reactor thermionic system. The models estimate performance and mass for the components in each of these systems.
