摘要

A process and an installation for the securing against excessive pressure in a prestressed concrete pressure vessel of a gas cooled high temperature reactor and for the prevention of activity release into the environment. The process comprises three steps and in each step pressure reducing installations become effective upon the rise of pressure in the prestressed concrete pressure vessel over a predetermined value. In the first step the pressure vessel is relieved by means of the operational gas purification apparatus and a conveying blower into the storage vessels for the cooling gas. In case of a further rise in pressure, in a second step a discharge path equipped with a safety valve and a check valve is opened, which also relieves into the storage vessels while by-passing the gas purification installation. In the third step, if the pressure continues to rise over a predetermined value, a line closed during normal operation by a rupture disk, is open, said line being connected with the discharge path and opening into the air circulation installation of the nuclear reactor plant. The air circulation installation is connected by means of a filter system with an exhaust stack.
