Closing device for the temporary flow medium-tight closure of a chamber taking up the reactor vessel of a nuclear reactor
Description
The reactor pressure vessel in nuclear reactors is generally placed in a chamber which can be flowded for radiation shielding whilst the fuel elements are exchanged. The invention deals with a closing device to close off the chamber flow medium-tight, enabling a fast closing and opening. According to the invention, screw spindles are proposed for this purpose.
