The method for preparing to reload a nuclear reactor, according to claim 1, further comprising the step of:dismantling said pressure flange from said reactor monoblock housing in a stopped configuration, after the steps of installing said plug transportation device on said reactor plug and the step of installing said additional cargo on said upper end of said plug transportation device. 3. The method for preparing to reload a nuclear reactor, according to claim 1, further comprising the step of:sealing between said guide channel and said cable reduction box with a sealing member. 4. The method or preparing to reload a nuclear reactor, according to claim 1,wherein the step of replacing internal media of said inner cavity of said cable reduction box is comprised of:checking tightness of said inner cavity of said cable reduction box with overpressure;removing a gas-air mixture from said inner cavity of said cable reduction box into a ventilation with gas medium-control; andfilling said inner cavity of said cable reduction box with inert gas. 5. The method for preparing to reload a nuclear reactor, according to claim 1,wherein the step of installing said reloading armor on said guide channel is comprised of:fixing said upper support surface of said guide channel on a ceiling of said reactor well. 6. The method for preparing to reload a nuclear reactor, according to claim 1,wherein the step of replacing internal media of said inner cavity of said reloading armor and said inner cavity of said guide channel is comprised of:checking tightness of said inner cavity of said reloading armor and said inner cavity of said guide channel with overpressure;removing a gas-air mixture from said inner cavity of said reloading armor and said inner cavity of said guide channel into a ventilation with gas medium control; andfilling said inner cavity of said reloading armor and said inner cavity of said guide channel with inert gas. 7. The method for preparing to reload a nuclear reactor, according to claim 1,wherein the step of moving said plug transportation device with said reactor plug into said reloading armor comprises the steps of:moving said locking elements of said cable reduction box with said movement drive to said stops corresponding to said locking elements so as to move said plug transportation device and said reactor plug to an upper position in said cable reduction box;lowering said automatic grip of said reloading armor to said plug transportation device;coupling of said automatic grip of said reloading armor with said plug transportation device;moving said automatic grip of said reloading armor with said reactor plug into a highest position in said reloading armor;sealing and closing said damper of said reloading armor; andsealing and closing said damper of said cable reduction box. 8. The method or preparing to reload a nuclear reactor, according to claim 7,wherein said guide channel further comprises a stop member at said damper of said guide channel, andwherein the step of lowering said automatic grip of said reloading armor to said plug transportation device further comprises the step of:stopping said automatic grip of said reloading armor against said stop member of said guide channel. 9. The method for preparing to reload a nuclear reactor, according to claim 1,wherein the step of transporting said reloading armor with a said reactor plug to said shaft is carried out by a cargo crane and a lifting beam, andwherein the step of unloading said reactor plug from said reloading armor within said plug shaft is carried out by said cargo crane and said lifting beam. 10.
