Circuit arrangement of steam generator in sodium circuit of fast reactor nuclear facility

摘要

In the circuit arrangement of steam generator in sodium circuit of fast reactor nuclear facility, there are incorporated particularly a pump, a balancing reservoir (2), sodium piping and at least one steam generator module (1) with a sodium inlet chamber (17) and outlet chamber (18) being connected with each other via tube plates (21) by at least one heat transfer pipe (19). Each module (1) of the steam generator is connected on the side of sodium inlet and via its inlet chamber (17) to an inlet collector (5) with an inlet sodium pipe sleeve (6), an inlet connecting piping (7) with integrated safety element (9) being at the same time connected to a balance pipe (8) opening into at least one first tank (3) of the emergency control system. On the side of the sodium outlet, each steam generator module (1) is separately connected via its outlet chamber (18) and through an outlet connecting piping (10) to the balancing reservoir (2), which is further connected to both the sodium circuit through the mediation of an outlet sodium pipe sleeve (16) and at the same time to at least one first tank (3) of the emergency control system through the mediation of at least one balance pipe (12) provided with at least one first membrane (11). Said first tank (3) of the emergency control system is further at the same time connected to a discharge hole (15) via at least one connecting emergency pipe (14) provided with at least one second membrane (13) and via at least one second tank (4).
