<p>The present invention is to solve the problem of extending the limited area boundary distance of a nuclear power plant. It includes a cooling water storage part installed in a containment building, a reactor coolant system installed in the containment building or a boundary part which surrounds the reactor coolant system to prevent the leakage of a reactive material from a pipe connected to the reactor coolant system to the containment building, a connection pipe which connects the interior space of the boundary part and the cooling water storage part to guide the internal air of the boundary part formed due to a difference in pressure between the boundary part and the cooling water storage part and the movement of the reactive material included in the air to the cooling water storage part, and an injection part which is arranged to be dipped in a cooling water stored in the cooling water storage part and connected to the connection pipe to inject the reactive material passing through the connection pipe to the cooling water storage part.</p> |
