3. DESCRIPTION OF PROGRAM OR FUNCTION - The program ALKASYS is used for the creation of design concepts of multimegawatt space power systems that employ potassium Rankine power conversion cycles.


4. METHOD OF SOLUTION - ALKASYS calculates performance and design characteristics and mass estimates for the major subsystems composing the total power system. Design and engineering performance characteristics are determined by detailed engineering procedures rather than by empirical algorithms. Mass estimates are developed using basic design principles augmented in some cases by empirical coefficients determined from the literature. The reactor design is based on a fast spectrum, metallic-clad rod fuel element containing UN pellets.


5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM - ALKASYS was developed primarily for the analysis of systems with electric power in the range from 1,000 to 25,000 kW(e) and full-power life from 1 to 10 years. The program should be used with caution in systems that are limited by heat flux (which might indicate need for extended surfaces on fuel elements) or criticality (which might indicate the need for other geometries or moderators).


6. TYPICAL RUNNING TIME - The sample case using the direct cycle took about five minutes on an IBM PX/XT under the DOS operating system.
