<p>The present invention relates to a cooling water system cooling the core where nuclear fission occurs in a nuclear reactor, and to the nuclear reactor comprising the same. The cooling water system comprises: a first and a second inlet header supplying cooling water into the core, and separated from each other; a first and a second outlet header formed to correspond to the first and the second inlet header, where the cooling water passing the core is spilled; a first balance line where the cooling water moves caused by pressure difference between the first and the second outlet header to reduce hydraulic pressure difference between the first and the second outlet header; and a first control valve installed in the first balance line and controlling the flux of the cooling water so that the cooling water does not flow into the first balance line if the hydraulic pressure difference between the first and the second inlet header is higher than the hydraulic pressure difference between the first and the second outlet header, wherein the first outlet header is connected with the first inlet header, and the second outlet header is connected with the first header so that pulmonary circulation is formed.</p> |
