Container, device and method for encapsulating a fuel rod or a fuel rod portion in a gas-tight manner

摘要

A container, a device, and a method encapsulate a fuel rod or a fuel rod portion in a gas-tight manner. The container has a hollow cylindrical container part which is closed at the free ends of the container part in a fluid-tight manner by a respective single-piece closure stopper. The closure stopper is provided with a channel that fluidically connects the flushing chamber of the container part to the exterior exclusively in an intermediate position, which is assumed prior to reaching an end position during the assembly process and in which the closure stopper additionally projects out of the container part by an axial length compared to the end position of the closure stopper.

主权项

1. A container for a gas-tight encapsulation of a fuel rod or of a fuel rod section, the container comprising:
unipartite closure plugs each having a duct formed therein; and a hollow cylindrical container part having two free ends closed off in a fluid-tight manner by said unipartite closure plugs, said hollow cylindrical container part having a scavenging chamber fluidly connected to an exterior via said duct exclusively in an intermediate position assumed during an assembly process before an end position is reached and in the intermediate position said unipartite closure plugs projecting out of said hollow cylindrical container part by an axial projecting length in relation to an end position of said unipartite closure plugs.
