ABSTRACT:
A pressurized water reactor system having circulation means outside the containment vessel for the circulation of loss of coolant emergency water is provided which prevents exposure of such water to the atmosphere. The system includes an enclosure, separate from the containment vessel, the interior of the enclosure being sealed to the atmosphere and containing a pumping means, and encased inlet and outlet conduits communicating between the interior of the containment vessel and the pump means within the enclosure. The enclosure may also contain a heat exchange means, while the emergency water storage tank can be positioned in the containment vessel, in the enclosure, or separate from both. Provision is also made for use of the pump in the enclosure for circulation of residual heat removal coolant water.
