エネルギを図ることができる。As explained above, the present invention uses the configuration as described above to cool the cooling water heated in the cooler for cooling the atmosphere inside the reactor containment vessel to the outside air or ventilation nitrogen in the air-cooled cooler.
Since the cooling is done by the exhaust air of the equipment, etc., the plant 1lrij';' + uses cooling water from the cooling system,
There is no need to do so, and the capacity of the plant auxiliary cooling system can be reduced. Moreover, the cooling water piping is only in the reactor building.
Or (I'i only need to be provided in the immediate vicinity of <,l
ij' Take in water11. Since the piping of the plant auxiliary cooling system that returns to the sea after exchanging heat can be completely reduced, plant construction costs can be reduced. Nitrogen-cooled coolers will be required, but the capacity of the seawater-freshwater heat exchanger in the plant extraction cooling system can be reduced, so not only the construction cost but also the cost of 7. In addition, if necessary, heating can be done using exhaust heat.
You can save energy.
