Book Description

This report presents the results of a six-month design and analysis study to develop and furnish a conceptual design of a radioisotope-powered thermodynamic engine to serve as the power source in an implantable circulatory support system. The study establishes the technical feasibility of a Stirling cycle engine using radioisotope fuel. Thermodynamic operating principles are given, and design and operating details of the power source are described. Shielding requirements and radiation level at the power source surfaces are presented parametrically."
