Abstract
A passive safety system comprises a heat exchanger, a thermoelectric element, and a fan unit. The heat exchanger is located inside a containment. The heat exchanger allows for temperature of atmosphere in the containment to be reduced. The thermoelectric element is disposed within the heat exchanger. The thermoelectric element is configured to generate electricity due to a temperature difference. The fan unit receives electricity generated by the thermoelectric element. The fan unit is configured to increase flow rate of fluid inside the containment. A nuclear power plant can include the passive safety system.
Claims13
A passive safety system, comprising:
- a passive containment cooling system;
- a heat exchanger
- formed at a space inside a hermetic containment, and
- allowing heat exchange of internal atmosphere of the containment introduced therein,
- such that temperature of the internal atmosphere is reduced,
- when an accident occurs in a reactor system disposed within the containment;
- a thermoelectric element disposed within the heat exchanger and configured to produce electricity
- due to a temperature difference between the internal atmosphere and a cooling fluid, heat-exchanged with the internal atmosphere,
- when the cooling fluid performs the heat exchange with the internal atmosphere within the heat exchanger;
- and
- a fan unit
- connected to the thermoelectric element via an electricity path to receive the electricity produced from the thermoelectric element and
- configured to form a flow of fluid inside the containment.
