Abstract
A method for producing microencapsulated fuel pebble fuel more rapidly and with a matrix that engenders added safety attributes. The method includes coating fuel particles with ceramic powder; placing the coated fuel particles in a first die; applying a first current and a first pressure to the first die so as to form a fuel pebble by direct current sintering. The method may further include removing the fuel pebble from the first die and placing the fuel pebble within a bed of non-fueled matrix ceramic in a second die; and applying a second current and a second pressure to the second die so as to form a composite fuel pebble.
Claims10
A nuclear fuel pebble comprising:
- an inner fuel pebble including fuel particles microencapsulated within a fully ceramic matrix;
- and
- a non-fueled matrix ceramic surrounding the inner fuel pebble.
