FUEL ELEMENT FOR NUCLEAR REACTORS AND METHOD FOR ITS MANUFACTURE
Patent
·
OSTI ID:4842274
The diffusion of gaseous fission products from graphite canned fuel elements is retarded by incorporating in the graphite some carbon black or a carbide or nitride of Al, Zr, Ti, Ba or Si. This can be done by impregnating the finished graphite body with a suitable fluid compound and forming the desired substance in situ, or by adding this substance or a suitable compound during the manufacture of the graphite body. The retarders can be homogeneously dispersed or form a separate layer. Use of these fuel elements decreases the contamination of the reactor. (NPO)
