facebook.com The rotor velocity is 3000 rpm. The rated pump delivery is 8500 cu.m/h at a head of 200 m w.g., speed - one thousand rpm, electric motor output - 5500 kW. By bundling radio-frequency (RF) vitality on the same line with an electric current, shield control cable data might be transmitted without the need for a separate data line. The condensate of the steam spent in the turbines is conditioned in the ion-exchangers, heated within the heat exchangers of the regenerative heating system, deaerated and on passing by means of strainers is fed again by the electric feedwater pumps over feed pipelines to the separators of the circulating circuit. The delivery pipelines convey water from the principle circulating pumps to the strain header. The gear and pipelines are protected against extreme strain rise by a system of steam dumping amenities which dump excess steam into the turbine condensers or into the condensation pools of the accident isolation system.



































The circulating circuit of the reactor is a system composed of gasoline channels, steam/water and water strains, steam separators, essential circulation pumps, pressure, suction and distribution headers with associated piping. The light water circulates over a closed circuit. The Ignalina nuclear energy plant, like all stations with RBMK reactors, has a direct cycle configuration - saturated steam formed within the reactor correct by passing the sunshine water via the reactor core is fed to the turbine at a strain of 6,5 MPa. Light water coolant is fed into the lower finish of the gas channels. The coolant flow distribution among the gasoline channels as a perform of the core vitality launch is managed by shutoff management valves following the indications of flow meters mounted on the inlet of water supply line to each gas channel. Each loop incorporates two horizontal kind steam separators interconnected on the water and steam sides. Steam is conveyed from every separator to the turbines over two steam strains. The steam piping is so organized that every steam separator is connected with two turbines. The turbines are double-move tandem machines (one excessive-stress cylinder and 4 low-pressure cylinders) with reheat. The thermal power output of 1 unit is 4800 MW, the electrical power capacity is 1500 MW.



































Each unit comprises two K-750-65/3000 turbines with 800 MW generators. The unit with one reactor comprises two 750 MW turbines. The turbines are managed by cumputer-based mostly management system ASUT-750. 40-forty three water provide lines are branched off each distribution header. The biological shield is manufactured from carbon steel, serpentine crushed stone and gravel, concrete, sand, water. The fuel channels are tubes whose lower and higher parts are fabricated from corrosion-resistant steel, while the central part is manufactured from Zircalloy. The vertical graphite stack columns comprise gasoline channels and control rod channels. The graphite stack is carried by a welded steel construction resting on a concrete foundation. The principle structural aspect of the reactor, a graphite stack with gasoline channels, absorber-rods and surrounding steel structures, is housed in a concrete vault. On high the graphite stack is spanned over by an upper steel structure resting on the annular water tank of the biological shield.



































The split graphite rings within the channels provide thermal contact with the graphite bricks of the stack. Provision is made to change the gas channels and control rod channels on the shut-down and cooled reactor. A welded shell enclosing the graphite stack, as properly as the upper and backside steel structures form a sealed reactor house. To prevent graphite oxidation and to improve heat transfer from graphite to gas channels, the reactor house is filled with a helium-nitrogen mixture. From the gasoline channel the coolant in the form of steam/water mixture goes into the separators. Each gas meeting contains 18 gasoline rods within the type of sealed Zircalloy tubes that are filled with uranium dioxide pellets. Welding cable is suitable for welding applications on meeting traces, development and shipbuilding. The suction and stress headers of every loop are interconnected by six bypass strains, every provided with a stop gate and a examine valve.
