Fuel rod for nuclear reactors
Description
The fuel or breeder element with fission gas plenum has hollow spaces on the central part of the fuel or breeder material volume, which are filled with sodium. During operation, this sodium provides a second heat transport mechanism, as the sodium evaporates, rises into the fission gas plenum, condenses on the metal sleeve there and returns to the fuel or breeding zone under gravity or capillary effect.

Das Brenn- oder Brutelement mit Spaltgasplenum weist im zentralen Bereich des Brenn- oder Brutstoffvolumens Hohlraeume auf, die mit Na gefuellt sind. Waehrend des Betriebes bildet dieses Na einen zweiten Waermetransportmechanismus, da das Na verdampft, zum Spaltgaslenum aufsteigt, dort an der metallischen Umhuellung kondensiert und durch Schwerkraft oder Kapillarwirkung in die Brenn- oder Brutstoffzone wieder zurueckkehrt.
