Burnable absorber-containing nuclear fuel pellets and formation of the same
Creators
Description
The method is described of forming nuclear fuel pellets having a burnable absorber combined therewith comprising: combining discrete particles of a boron-containing burnable absorber and discrete particle of a boron-containing glass composition to form a coating mixture, the boron-containing glass composition comprising 20-30 percent by weight B/sub 2/O/sub 3/; applying the coating mixture to the surface of nuclear fuel pellets; heating the nuclear fuel pellets having the coating mixture on the surface to an elevated temperature sufficient to melt the boron-containing glass, and incorporate the boron-containing burnable absorber in the resultant melt while preventing reaction between the burnable absorber and the boron-containing glass; and cooling the pellets
