ABSTRACT:
The nuclear reactor installation is provided with a double-wall pressure vessel which is surrounded by a heat sink. A flood tank is provided outside the vessel in order to supply air as a heat-insulating agent to the chamber defined by the pressure chamber wall during normal operation and to supply water as a heat-conductive agent in response to a disturbance in reactor core cooling.
The cover on the pressure vessel is also provided with a chamber to which air or water can be delivered. A closure member which can be activated by fusible element is incorporated in the cover to permit flooding of the cover chamber in response to an excessive heat within the pressure vessel.
