Six Cut-Throat Shield Control Cable Tactics That Never Fails > 자유게시판

The reactor course of monitoring system provides the operating personnel with info and inputs knowledge into the control and safety system. The system monitoring tightness of gas rod cladding specially designed for the RBMK-1500 reactors and applying modern methods for detection of defective gas rods and pc-primarily based data logging offers the core radiation management. The vertical graphite stack columns include gasoline channels and management rod channels. Provision is made to replace the gas channels and management rod channels on the shut-down and cooled reactor. The unit with one reactor comprises two 750 MW turbines. The separated water, in mixing with the conditioned, heated, and deaerated feedwater goes by way of the downcomers to the suction header and then is conveyed through suction pipes to the four fundamental circulating pumps considered one of which is saved within the stand-by responsibility. The thermal energy output of 1 unit is 4800 MW, the electrical energy capability is 1500 MW.

Eeach generating unit is supplied with a gasoline dealing with system and unit management room. Radioactive discharge into air and water is monitored constantly utilizing instruments of the computerized radiation dose control system. The computerized radiation doze control system at the nuclear power plants with reactors of the RBMK-1500 sort is provided with services monitoring radiation exposure of all elements and techniques of the station. To cut back radioactive aerosol emissions on the nuclear energy plants with the RBMK-1500 reactors provision is made for purification facilities absorbing aerosols by particular filters. The nuclear energy plants with the RBMK-1500 reactors use a closed-circuit water provide system. The Ignalina nuclear power plant, like all stations with RBMK reactors, has a direct cycle configuration - saturated steam formed in the reactor proper by passing the sunshine water by way of the reactor core is fed to the turbine at a pressure of 6,5 MPa. The turbine room, waste gasoline purification and water conditioning rooms are widespread for all of the units. The equipment and pipelines are protected in opposition to extreme pressure rise by a system of steam dumping facilities which dump excess steam into the turbine condensers or into the condensation swimming pools of the accident isolation system.

The system supplies begin-up, automatic upkeep of energy on the set stage, permits control of power distribution alongside the radius and heightwise of the core, compensates for gas burn-up, offers protection of the reactor beneath emergency circumstances. The remaining rods are unified and serve the perform of reactivity scramming, automated maintenance of the reactor energy release on the set level, management of vitality distribution over the core radius. The condensate of the steam spent in the turbines is conditioned in the ion-exchangers, heated in the heat exchangers of the regenerative heating system, deaerated and on passing by way of strainers is fed again by the electric feedwater pumps over feed pipelines to the separators of the circulating circuit. The light water circulates over a closed circuit. The supply pipelines convey water from the main circulating pumps to the strain 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 foundation. Out of the total variety of rods, forty ones are used for energy distribution management by means of the hight of the active zone of the reactor. 24 rods carry out the perform of immediate emergency safequard introduced into the energetic zone inside 2.5 seconds underneath particular emergensy situations. The bypass traces maintain natural circulation of coolant at emergency shutdown of a predominant circulating pump. The circulating circuit of the reactor is a system composed of gasoline channels, steam/water and water lines, steam separators, fundamental circulation pumps, pressure, suction and distribution headers with related piping. The system monitoring tightness of the gas meeting claddings contains scintillation gamma-spectrometer sensors, tools, to make sure operation and motion of sensors in the intertube house of the steam traces, and services for processing and output of knowledge. The suction and strain headers of every loop are interconnected by six bypass lines, each provided with a cease gate and a test valve. The suction line of every primary circulating pump is provided with a stop gate, the delivery line (down the flow) mounts a examine 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., velocity - one thousand rpm, electric motor output - 5500 kW.
