It consists of a closure valve (8), a safety valve (10) and a glove discharge valve (12), these three valves placed inside a chamber of armor (15) adjacent outward to the concrete wall (4) of reactor safety receptacle. The casing (7) of the closure valve (8) is directly welded to the external end of step (6) of the steam pipe. The security valve is directly joined by one end with an additional hole (9) of the closure valve (8) and by the other end with a hole (10) of the ducting gate valve (12).
