A method is specified for operation of an arrangement having at least one superconducting cable, which is surrounded by a cryostat which consists of two metallic tubes, which are arranged concentrically with respect to one another and enclose vacuum insulation between them. The cryostat surrounds not only the cable but also a cavity for a pressurized coolant to pass through. A reservoir area, which is connected to the cryostat, for the coolant is arranged at least at one end of the cryostat and a pump is used which forces the coolant into the cryostat during operation of the arrangement. A valve is arranged at least in the supply path of the coolant from the reservoir area to the cryostat, which valve is open during operation of the arrangement, is connected to at least one unit monitoring the soundness of the cryostat and is blocked when a signal which corresponds to a fault message is present from the monitoring unit, in order to interrupt the supply of the coolant to the cryostat.
