The invention relates to a semi-submerged small-waterplane-area mobile platform type marine
nuclear power station belonging to the technical field of offshore
engineering equipment and comprising a
deck, small-waterplane-area upright posts, bottom
hull shells, strut rails, an anchor chain, a nuclear generating device
peripheral watch box, an
electric power pylon, a revolving ring, an anchor, a
nuclear reactor and a converting
station, wherein one ends of the eight small-waterplane-area upright posts are respectively arranged on the two bottom
hull shells, and the other ends are fixedly connected with the bottom surface of the
deck; both ends of the four strut rails are respectively fixedly connected with the side surfaces of the two bottom
hull shells; and the nuclear generating device is arranged on the
deck. The marine
nuclear power station can be fixed in a certain sea area for long-term work and can also be towed by a tugboat to arbitrarily move to change the workplace. The invention has high
generating capacity, long service life, high safety, fuel saving, small resistance in
towing and high stability, and can endure severe sea conditions. The invention has important scientific research value, important industrial application prospect as well as military and national defense values and obvious
economic benefits and
social benefits.
