るいは防波堤２Ｉ内の淡水を利用してもよい。FIG. 1 is a diagram showing an offshore nuclear power plant 2 according to the present invention. This offshore nuclear power plant 2
has a breakwater 21. This breakwater 2I is for preventing waves from the open ocean, is provided on the seabed surface B with its top protruding above the sea surface, and is formed into an annular shape in plan view. A waterproof surface 22 is formed on an inwardly facing wall surface of the breakwater 21 and a seabed surface B surrounded by the breakwater 21. This waterproof surface 22 is a wall for preventing seawater S from outside the breakwater 21 from entering inside, and is made of glass fiber, a vinyl sheet, or the like as a waterproof material. Breakwater 2 like this
The inside of 1 is filled with fresh water W. This freshwater W is
This is to float the purge containing the nuclear power plant and reduce corrosion of the purge. The water level of this freshwater W is made higher than the water level of the seawater S outside the breakwater 2I at tide a, and by maintaining the water pressure inside the breakwater 21 higher than the water pressure outside the breakwater 21,
This prevents seawater S from entering the inside from the outside. A purge 24 in which a nuclear power plant 23 has been constructed is floating on the surface of the fresh water W. Note that, as cooling water for the nuclear power plant 23, seawater may be introduced from outside the breakwater 21 through a tunnel or the like, or fresh water within the breakwater 2I may be used.

The purge 24 with the construction of 3 is towed and moored at a predetermined position. Then, a breakwater 21 is constructed around this purge 24. Next, the seawater inside the breakwater 21 is pumped out, and the sides and bottom of the purge are coated with a final coating for corrosion resistance. Thereafter, fresh water is introduced from the fresh water source into the inside of the breakwater 21 to fill it and float the purge.

Since waterproof surfaces are provided on the walls facing inward and on the seabed surface inside the breakwater, corrosion of the purge can be suppressed,
Therefore, it is possible to reduce the effort and cost for rust prevention measures, and it is also possible to prevent seawater from entering the inside of the breakwater.
