1. A floating nuclear power reactor, comprising:
a floating vessel having a bottom positioned beneath the water level of a body of water, sides extending upwardly from said bottom, and an upper end which is positioned above the water level of the body of water; said floating vessel including an upstanding cylindrical support structure having a lower end, an upstanding cylindrical side wall, having inner and outer surfaces, and a closed upper end; a nuclear power reactor positioned within said cylindrical support structure; said nuclear power reactor including an upstanding containment structure having a lower end positioned on said bottom of said floating vessel, an upstanding side wall, having upper and lower ends, which is in engagement with said inner surface of said side wall of said cylindrical support structure and a domed upper end; said containment structure defining a sealed interior compartment, having upper and lower ends; said domed upper end of said containment structure and said upper end of said side wall of said cylindrical support structure and said closed upper end of said cylindrical support structure defining a vent chamber; said vent chamber being filled with a filter material; at least one first steam exhaust pipe extending from said vent chamber to the atmosphere; at least one second steam exhaust pipe extending from said upper end of said interior compartment of said containment structure into said vent chamber; an upstanding reactor vessel, having upper and lower ends, is positioned in said interior compartment of said containment structure; said reactor vessel having an interior compartment with upper and lower ends; a third steam exhaust pipe extending from said upper end of said interior compartment of said reactor vessel outwardly through said containment structure to a turbine; a normally open valve imposed in said third steam exhaust pipe; a by-pass steam exhaust pipe extending from said third steam exhaust pipe, outwardly of said containment structure, to said vent chamber; a normally closed valve in said by-pass steam exhaust pipe; at least one first return pipe, filled with a liquid, extending outwardly from said upper end of said interior compartment of said reactor vessel into said interior compartment of said containment structure, thence downwardly, and thence inwardly into said interior compartment of said reactor vessel at said lower end thereof, and thence upwardly within said interior compartment of said reactor vessel to form a closed loop return pipe; at least one first water passageway, having inner and outer ends, extending through said bottom of said containment structure; said outer end of said first water passageway being in fluid communication with the body of water; said inner end of said first water passageway being, in fluid communication with said interior compartment of said containment structure; a first hatch associated with said first water passageway; said first hatch being movable between a closed position and an open position; means associated with said first hatch which yieldably urges said first hatch to said open position; said first hatch, when in said closed position, closing said first water passageway; said first hatch, when in said open position, permitting water from the body of water to flow inwardly through said first water passageway into said interior compartment of said containment structure; a first latching means associated with said first hatch which is movable between a latched position and an unlatched position; said first latching means, when in said latched position, maintaining said first hatch in said closed position; said first latching means, when in said unlatched position, permitting said first hatch to move from said closed position to said open position; a first condition responsive actuator associated with said first latching means to move said first latching position from said latched position to said unlatched position upon the condition within said containment structure reaching a predetermined level; at least one second water passageway, having inner and outer ends, extending through said bottom of said containment structure; said outer end of said second water passageway being in fluid communication with the body of water; said inner end of said second water passageway being in fluid communication with said interior compartment of said reactor vessel; a second hatch movably associated with said second water passageway; said second hatch being movable between a closed position and an open position; means associated with said second hatch which yieldably urges said second hatch to said open position; said second hatch, when in said closed position, closing said second water passageway; said second hatch, when in said open position, permitting water from the body of water to flow inwardly through said second water passageway into said interior compartment of said reactor vessel; a second latching means associated with said second hatch which is movable between a latched position and an unlatched position; said second latching means, when in said latched position, maintaining said second hatch in said closed position; said second latching means, when in said unlatched position, permitting said second hatch to move from said closed position to said open position; and a second condition responsive actuator associated with said second latching means to move said second latching means from said latched position to said unlatched position upon the condition within said reactor vessel reaching a predetermined level. |
