A nuclear reactor is positioned on a barge which floats on the water of a water tank. The water tank includes a bottom wall, first and second end walls and first and second side walls. The bottom wall includes a lower layer of concrete, an intermediate layer of water impervious material positioned on the lower layer of concrete, and an upper layer of concrete positioned on the intermediate layer of water impervious material. Each of the first and second end walls and the first and second side walls includes an outer layer of concrete, an intermediate layer of water impervious material positioned at the inner side of the outer layer of concrete, and an inner layer of concrete material positioned at the inner side of the intermediate layer of water impervious material.

A marine power structure includes a building structure adapted to float on a body of water having a water surface. The mobile structure is transportable to a deployment location. The marine power structure also includes a nuclear enclosure disposed within in the building structure with a nuclear reactor disposed therein. A primary coolant system is connected to the nuclear reactor permitting heat generated by the nuclear reactor to be transferred thereto. At least one stabilizer is provided. The stabilizer is adapted to engage the building structure. The at least one stabilizer assists to maintain the stability of the building structure at the deployment location.

A floating nuclear power reactor including one or two nuclear power reactors positioned in a floating vessel such as a barge or the like. Means is disclosed for flooding the containment structure of the nuclear reactor and for flooding the reactor vessels to cool the same.

A system is provided for use with a nuclear reactor which is mounted on a barge and which floats in a water tank. The system includes at least one water pipe which extends from a source of water to the interior of the tank. The system also includes a pipe which permits the drainage of water from the water tank. Valves are imposed in the piping so that the water in the tank will have a desired level and temperature. The system also enables fresh water to be supplied to the containment interior of the reactor. Further, the system includes piping and valves to supply water to the condenser and to drain water from the condenser. The system also includes flexible and slack tubular sections positioned in the piping between the barge and the water tank which allows the barge to move while maintaining the integrity of the tubing.

An emergency cooling water system for a nuclear reactor which is mounted on a barge which floats in a water tank. The nuclear reactor includes an upstanding containment member having an interior compartment. At least one, and preferably two or more, cold water tubes are provided which have inner and outer ends with the outer ends of the cold water tubes being in communication with a source of cold water. The cold water tubes extend through the tank and the barge and have their inner ends in communication with the interior compartment of the nuclear reactor. In an emergency situation, cold water from the source of cold water is fed into the interior compartment of the containment member of the nuclear reactor.
