Embodiment Construction
[0031] [31] Figure 1 shows the main circuit 1 of a pressurized water nuclear reactor. The circuit 1 has a tank 2 in which a nuclear fuel assembly, a steam generator 4 equipped with a primary part (parties primaire) and a secondary part (partie secondaire), a primary pump 6 and a stabilizer 8 are arranged. The box 2, the steam generator 4 and the pump 6 are connected by a main-stage pipe section 10. Circuit 1 is equipped with main-stage water, which is pumped by pump 6 toward tank 2, passes through tank 2, undergoes heating, contacts the fuel assembly, and then passes through steam generator 4 before returning to the suction of pump 6 The main part of the. The primary water heated in the tank 2 releases its heat to the secondary water in the steam generator 4 through the secondary part of the generator. The secondary water circulates in a non-illustrated secondary circuit in a closed loop. It evaporates as it passes through the generator 4, and the steam thus produced drives a stea...
