<p>The present invention relates to an exhaust facility of a passive residual heat removal system having a heat exchanger to remove the heat of steam received from a steam generator. The exhaust facility comprises: a first steam pipe connecting the steam generator to a turbine system in order to enable the steam to flow into the turbine system; a second steam pipe branching off from a certain part of the first steam pipe and connected to the heat exchanger in order to enable a part of the steam to flow into the heat exchanger; and a gas exhaust pipe branching off from a certain part of the second steam pipe and connected to the first steam pipe. According to the present invention, a part of the steam flowing into the second steam pipe is circulated through the gas exhaust pipe by the internal pressure difference of the first steam pipe, and discharged into the turbine system.</p> |
