Abstract

The invention relates to a method and an arrangement for providing an emergency supply to a nuclear installation. The arrangement comprises a container (10) with a plurality of permanently installed devices and at least one motor (22), one generator (26), one pump (24), one fuel tank (14) and one transformer (34), wherein the pump and the generator are functionally connected to the motor in order to activate said motor.

Claims

1. An arrangement to provide an emergency supply to a nuclear installation (59) with a container (10) with several integrated facilities, comprising at least

a motor (22),

a generator (26),

a pump (24),

a fuel tank (14),

a transformer (34),

whereby the pump and the generator are functionally connected to the motor to actuate said pump and generator,

characterized in that

the fuel tank (14) is situated in the region of the center of gravity of the container (10).

2. The arrangement of claim 1,

characterized in that

the motor (22) is embodied as a Diesel motor, in particular a turbocharged Diesel motor, with two shaft ends, whereby one of the shaft ends is connected to the pump (24), preferably embodied as a self-priming pump designed for waste water, in particular a spiral casing pump, and the other shaft end is connected to the generator (34).

3. The arrangement of claim 1,

characterized in that

the fuel tank (14) with a holding capacity of at least 10 m³, in particular 15 m³, is embodied bullet-proof and in particular is subdivided into relaxation zones by partition plates (16,18).

4. The arrangement of at least one of the preceding claims,

characterized in that

the container (10) contains a decontamination area (36) with a shower.

5. The arrangement of at least one of the preceding claims,

characterized in that

the container (10) is at least a 40 ft container with walls of tempered steel plate, in that the fuel tank (14) is arranged in the center region of the container, in that—

viewed along the longitudinal container axis—

the motor (22), the generator (26), and the pump (24) are arranged on one side of the fuel tank while the transformer (34) and the possibly present decontamination area are arranged on the other side of the fuel tank.

6. The arrangement of at least one of the preceding claims,

characterized in that

the transformer (34) is arranged in the container in a radiation-protected fashion.

7. A method to provide an emergency supply to a nuclear installation using a pump and/or a generator that are independent of the nuclear installation,

characterized by

the use of a supply container with several permanently installed facilities, comprising at least:

a motor,

a generator,

a pump,

a fuel tank,

a transformer,

whereby the pump is integrated into a cooling water cycle of the nuclear pump, and/or the pump is used to pump cooling water from an external water feed into a cooling water cycle or sections thereof of the nuclear installation, and/or

the generator is connected to at least one cooling water pump of a nuclear installation.

8. The method of claim 7,

characterized in that

the transformer is connected to the controller, via which is supplied a power source, such as batteries, in the nuclear installation.
