Abstract: A nuclear power reactor which includes passive cooling and radiation scrubbing. The reactor includes a first containment member which is buried in the ground. A second containment member is positioned in the first containment member and has a reactor vessel therein. The discharge side of the reactor vessel is connected to a heat exchanger which drives a turbine which drives a device such as a generator. A source of water is provided which gravity feeds cooling water to the interior of the first containment member in the event of reactor overheating or over-pressurization. A radiation scrubber is provided for scrubbing radiation which may be in the first containment member or the second containment member.

Abstract: An underground nuclear power reactor having a hollow blast tunnel which extends from one end of a containment member which houses a nuclear reactor, heat exchanger, generator, etc. A hollow blast tunnel extends from one end of the containment member with a normally closed door positioned therebetween. The blast tunnel defines a blast chamber having a plurality of spaced-apart debris deflectors positioned therein. The blast chamber has an upper wall with a roof opening formed therein which is selectively closed by a roof portion. If the reactor needs to be repaired or replaced, the door is opened so that the reactor will pass therethrough into the blast chamber and outwardly through the roof opening. If the reactor explodes, the blast therefrom drives the debris therefrom through the door and into the blast chamber where the deflectors reduce the blast force as the debris passes through the blast chamber.

Abstract: An underground nuclear power reactor having a hollow blast tunnel which extends from one end of a containment member, and which houses a nuclear reactor, heat exchanger, generator, etc. The nuclear reactor, etc., are positioned on a movable support member. The blast tunnel defines a blast chamber having a plurality of spaced-apart debris deflectors positioned therein. The blast chamber has an upper wall with a roof opening formed therein which is selectively closed by a roof portion. If the reactor needs to be repaired or replaced, the roof portion is opened so that the reactor will pass therethrough into the blast chamber and outwardly through the roof opening. If the reactor explodes, the blast therefrom drives the debris therefrom through the blast door and into the blast chamber where the deflectors reduce the blast force as the debris passes through the blast chamber. A simplified cooling system is provided.

Abstract: 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.

Abstract: 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.

Abstract: A nuclear reactor is positioned on a barge which is floating in a water tank. A plurality of counter weight assemblies interconnect the barge with the tank to create a lifting force to the barge and to maintain the barge in a level position. Structure is also included for limiting horizontal movement of the counter weight of the counter weight assemblies.

Abstract: 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.

Abstract: 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.

Abstract: A protection system is provided for protecting a nuclear reactor positioned on a barge which is floating in the water of a tank. The system also includes suspension systems which permits the barge to move downwardly in the tank upon an aircraft, missile strike or earthquake to reduce the impact force of the strike. Each of the suspension systems includes a slack upper chain member, a taut intermediate chain member and a slack lower chain member. A padding material is positioned at the inner sides of the tank. Padding material may be placed of the ends and sides of the barge.
