<p>The facility enabling a tempory increased of the opening pressure of steam generator relief valves at a nuclear unit with VVER 440 /V-213/ reactor in case of an interfacing LOCA into steam generator is characteristic by the fact that the existing distribution system of the control air of the relief valves SiZ 1508 is supplemented by a control device R^¿P3 with the connection of the output lifting and loading air through new shut-off valves UV4, EV4 to the existing distribution system of control air which is supplemented with shut-off valves UV2, EV2, UV3, EV3 in the leg of loading air from R^¿P 1,2 and with an air storage tank from the side of the supply air, and equipped with shut-off valves UV1, EV1.</p> |
