Ceramic nuclear fuel or breeder material tablets and method of producing the same
Abstract
Abstract Ceramic fissionable fuel or breeder material tablet axially alignable with corresponding tablets for forming nuclear reactor fuel rods includes a substantially cylindrical member having a depression at opposite end faces thereof, the end faces respectively comprising a marginal zone of slightly sloping conical shape having an angle of inclination within a range of 0.5* to 30*, the inclined marginal zone defining, with the remaining surface of the respective end face, an annular contact edge for contacting an end face of another tablet axially alignable therewith, the annular contact edge being spaced from the peripheral edge of the end face a given distance so that compression forces acting on the annular contact edge when the tablet is in use in a nuclear reactor fuel rod, are absorbable by a spatial region of the table having adequate strength for absorbing the compression forces.
