摘要： Disclosed is a passive residual heat removal system and nuclear power plant equipment configured to alleviate a rise in an internal pressure of a primary containment vessel (17), even if fluid line breakage of a reactor pressure vessel (15) occurs and for whatever reason, supply of a coolant (2) to the reactor pressure vessel (15) fails.
This invention includes: a heat exchanger (1) provided at a position higher than a primary containment vessel (17); a condensate storage tank (5) disposed below the heat exchanger and above an upper end of a reactor core (13) placed in a reactor pressure vessel (15); a non-condensate gas discharge line (8) connected at a first end thereof to an upper section of the condensate storage tank (5) and at a second end thereof to a suppression pool (20); a second condensate discharge line (9) connected at a first end thereof to a position below that section of the condensate storage tank (5) to which the first end of the non-condensate gas discharge line (8) is connected, and at a second end thereof to the suppression pool (20); and a condensate return line (10) connected at a first end thereof to a position below that section of the condensate storage tank (5) to which the first end of the second condensate discharge line (9) is connected, and at a second end thereof to a side portion of the reactor pressure vessel (15), the side portion being above the upper end of the core (13).

摘要： A nuclear power plant has a reactor pressure vessel (1), a primary containment vessel (3) and a passive pressure suppression pool cooling system. The reactor pressure vessel (1) is installed in the primary containment vessel (3). A pressure suppression pool (7) filled with cooling water is formed in a lower portion of the primary containment vessel (3). The passive pressure suppression pool cooling system is provided with a steam condensing pool (5) in which cooling water is filled, disposed outside the primary containment vessel (3), a steam condenser (4) disposed in the steam condensing pool (5), a steam supply pipe (2) connecting the reactor pressure vessel (1) to the steam condenser (4), and a condensed water discharge pipe (6) connected to the steam condenser (4) for discharging condensed water generated in the steam condenser (4). Another end portion of the condensed water discharge pipe (6) is disposed in the pressure suppression pool (7).
