The reactor process monitoring system gives the working personnel with info and inputs data into the management and safety system. The system monitoring tightness of gasoline rod cladding specially designed for the RBMK-1500 reactors and making use of modern methods for detection of faulty gasoline rods and laptop-based mostly data logging gives the core radiation control. The vertical graphite stack columns comprise gasoline channels and control rod channels. Provision is made to change the gas channels and management rod channels on the shut-down and cooled reactor. The unit with one reactor contains two 750 MW turbines. The separated water, in mixing with the conditioned, heated, and deaerated feedwater goes by means of the downcomers to the suction header and then is conveyed by way of suction pipes to the four essential circulating pumps certainly one of which is stored within the stand-by duty. The thermal power output of one unit is 4800 MW, the electrical power capacity is 1500 MW.
Eeach producing unit is supplied with a fuel dealing with system and unit control room. Radioactive discharge into air and water is monitored repeatedly using instruments of the computerized radiation dose management system. The computerized radiation doze management system on the nuclear power plants with reactors of the RBMK-1500 type is provided with amenities monitoring radiation exposure of all components and systems of the station. To scale back radioactive aerosol emissions on the nuclear energy plants with the RBMK-1500 reactors provision is made for purification services absorbing aerosols by special filters. The nuclear power plants with the RBMK-1500 reactors use a closed-circuit water provide system. The Ignalina nuclear energy plant, like all stations with RBMK reactors, has a direct cycle configuration - saturated steam formed within the reactor proper by passing the light water through the reactor core is fed to the turbine at a stress of 6,5 MPa. The turbine room, waste gasoline purification and water conditioning rooms are common for all of the models. The equipment and pipelines are protected against excessive stress rise by a system of steam dumping facilities which dump excess steam into the turbine condensers or into the condensation pools of the accident isolation system.
The system gives begin-up, automatic maintenance of power at the set degree, allows management of energy distribution along the radius and heightwise of the core, compensates for gas burn-up, supplies protection of the reactor below emergency circumstances. The remaining rods are unified and serve the operate of reactivity scramming, automatic maintenance of the reactor energy release at the set stage, control of vitality distribution over the core radius. The condensate of the steam spent in the turbines is conditioned within the ion-exchangers, heated in the heat exchangers of the regenerative heating system, deaerated and on passing through strainers is fed again by the electric feedwater pumps over feed pipelines to the separators of the circulating circuit. The sunshine water circulates over a closed circuit. The supply pipelines convey water from the principle circulating pumps to the pressure header. The pumps are of a vertical, centrifugal, single-stage configuration. Conductor Size. Conductor Configuration.
The graphite stack is carried by a welded steel construction resting on a concrete basis. Out of the entire variety of rods, forty ones are used for power distribution management through the hight of the energetic zone of the reactor. 24 rods carry out the function of prompt emergency safequard launched into the lively zone within 2.5 seconds beneath particular emergensy situations. The bypass strains maintain natural circulation of coolant at emergency shutdown of a fundamental circulating pump. The circulating circuit of the reactor is a system composed of fuel channels, steam/water and water traces, steam separators, essential circulation pumps, pressure, suction and distribution headers with associated piping. The system monitoring tightness of the fuel assembly claddings includes scintillation gamma-spectrometer sensors, gear, to ensure operation and movement of sensors within the intertube area of the steam traces, and facilities for processing and output of knowledge. The suction and strain headers of each loop are interconnected by six bypass lines, every provided with a cease gate and a test valve. The suction line of every primary circulating pump is provided with a cease gate, the delivery line (down the stream) mounts a test valve, a throttle valve and a stop gate. The rated pump supply is 8500 cu.m/h at a head of 200 m w.g., speed - a thousand rpm, electric motor output - 5500 kW.
