Embodiment Construction

[0023]According to the present invention, techniques related to nuclear engine fuel are provided. More particularly, an embodiment of the present invention provides an enhanced fuel particle suitable for use in a laser inertial confinement fusion-fission power plant. Such an engine is described in more detail in our commonly assigned copending U.S. patent application Ser. No. ______, entitled “Control of a Laser Inertial Confinement Fusion-Fission Power Plant,” filed contemporaneously with this application, the contents of which are incorporated by reference. Merely by way of example, the invention has been applied to the design and fabrication of a robust tristructural-isotropic (TRISO) particle capable of high burn-up as well as a fuel pebble including a plurality of the robust TRISO particles. The methods and systems described herein are also applicable to other nuclear power plant designs. Additional discussion related to nuclear fusion-fission engines is provided in U.S. patent...

Abstract

A fuel particle for use in a fusion-fission nuclear engine includes a fuel kernel and a buffer layer surrounding the fuel kernel. The fuel particle also includes a pyrolytic carbon layer surrounding the buffer layer and a silicon carbide layer surrounding the buffer layer. The silicon carbide is characterized by a stress less than 450 MPa at 95% burn-up. The fuel particle further includes a second pyrolytic carbon layer surrounding the silicon carbide layer.
