Abstract (en)
[origin: US4427893A] Apparatus for storing spent fuel assemblies of a nuclear reactor including a fuel-assembly transport cask having a hollow chamber for receiving therein at least one fuel assembly and having a cover for gas-tightly closing off an opening to the hollow chamber, including means for supplying a trace gas into the hollow chamber, an additional cover defining a leakage detection chamber covering the cross-section of the opening to the hollow chamber, and a measuring device for the trace gas connected to the leakage detection chamber for monitoring gas-tightness of the closure of the opening to the hollow chamber, and method for using the apparatus.
Abstract (de)
Zur Lagerung von verbrauchten Brennelementen kann man Brennelement-Transportbehälter (2) einsetzen. Deren Dichtigkeit wird mit einem in den Transportbehälter (2) eingefüllten Spurengas, insbesondere Helium, ermittelt, das in einen Leckageerfassungsraum (11) gelangt, der als zusätzlicher Deckel (10) vorgesehen und mit einer Meßeinrichtung (16) für das Spurengas verbunden ist.
