Beschreibung
Zusammenfassung:	An apparatus and method of shielding radiation from a nuclear reactor having at least one fuel channel tube includes inserting a plug into an end of the fuel channel tube, providing a gas-tight seal with the plug in the fuel channel tube, and installing a flange about the plug and/or about the end of a sleeve also inserted within the fuel channel tube. In some embodiments, the sleeve receives the plug, and can protect the fuel channel tube and a wall aperture in which the fuel channel plug is received against damage. Also in some embodiments, radiation leakage can be reduced or prevented by the plug, the flange, and/or by a sealing arrangement between the sleeve and the plug and/or between the sleeve and the fuel channel tube.
