Variable cross-section nuclear reactor plant cabin and framework mechanism thereof

The invention belongs to the technical field of nuclear reaction equipment, and particularly relates to a variable cross-section nuclear reactor plant wall and a framework mechanism thereof. The invention aims to provide a variable cross-section nuclear reactor plant wall body and a framework mechanism thereof. The variable cross-section nuclear reactor plant wall body comprises a thick wall body framework mechanism, a thin wall body framework mechanism and a connecting mechanism for connecting the thick wall body framework mechanism and the thin wall body framework mechanism, the thick wall body framework mechanism and the thin wall body framework mechanism are connected into a complete nuclear reactor plant wall body framework mechanism through the connecting mechanism, and the change of the thickness of the section of the wall body is realized at the connecting mechanism. According to the technical scheme, the nuclear reactor plant with the wall body section thickness capable of being flexibly changed can
