Dynamics and Energetics of a ²⁵¹Cf-²⁵²Cf Power System

A combination fission-radioisotope compact power system involving the synergetic interaction of ²⁵¹Cf and ²⁵²Cf is considered. Based on a nonlinear point kinetics formulation of the coupled reactions combined with the parametric incorporation of design and operational variables, it is shown that a stable autonomous power mode is readily attainable. This system appears particularly suitable for very long-life unattended operation for space and terrestrial applications.
