You’ll need to take the highest off of the battery compartment to get entry to the holes for the screws. Once the motor is put in on the plate you may mount it to the top chassis plate utilizing three M3x10 screws and M3 nuts. The management and protection system is built of fail-protected and redundant gadgets utilizing integrated curcuits to receive and course of alerts from varied sensors, in addition to to current the reactor status data to the operator. The management and safety system is intended for reliable comply with-up of the reactor performance and its safe operation. On the upstream finish, every distribution header is provided with a cease gate, a verify valve and a mixer for water coming from the reactor emergency cooling system. The delivery pipelines convey water from the primary circulating pumps to the stress header. The equipment and pipelines are protected in opposition to extreme pressure rise by a system of steam dumping amenities which dump excess steam into the turbine condensers or into the condensation swimming pools of the accident isolation system.

The condensate of the steam spent in the turbines is conditioned within the ion-exchangers, heated within the heat exchangers of the regenerative heating system, deaerated and on passing through strainers is fed back by the electric feedwater pumps over feed pipelines to the separators of the circulating circuit. The refuelling machine is supplied with two systems of exact positioning over the fuel channel-optical/tv and make contact with. To stop graphite oxidation and to improve heat transfer from graphite to fuel channels, the reactor house is filled with a helium-nitrogen mixture. The system monitoring tightness of the gasoline assembly claddings contains scintillation gamma-spectrometer sensors, gear, to make sure operation and movement of sensors within the intertube area of the steam strains, and services for processing and output of information. A welded shell enclosing the graphite stack, as nicely as the upper and bottom steel buildings type a sealed reactor area. On high the graphite stack is spanned over by an upper steel structure resting on the annular water tank of the biological shield. The circulating circuit of the reactor is a system composed of fuel channels, steam/water and water traces, steam separators, major circulation pumps, stress, suction and distribution headers with related piping. 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 4 principal circulating pumps one among which is saved within the stand-by responsibility.

The suction and strain headers of every loop are interconnected by six bypass traces, each provided with a stop gate and a test valve. The bypass lines maintain pure circulation of coolant at emergency shutdown of a principal circulating pump. Steam is conveyed from every separator to the turbines over two steam strains. 40-forty three water supply lines are branched off every distribution header. The coolant circulation distribution among the many gasoline channels as a function of the core energy launch is controlled by shutoff management valves following the indications of circulate meters mounted on the inlet of water provide line to each gasoline channel. The stress header is related via pipes with 20 distribution headers. Feedwater flows from the header into downcomers by means of perforated nozzles. In the only terms, every little thing you hear from the principle output is committed to a recording tape. Control knowledge are displayed on the unit management board utilizing VDU, visual and recording instuments, varied announciation home windows and indicators, mimic diagrams and printers.

The control and monitoring methods provide reliable and secure operation of the key gear and maintain stable process parameters. A significant source of radiation from electronic merchandise is due to widespread-mode currents on the external cables. The RBMK-1500 reactor is supplied with special components and techniques making certain radiation safety of the nuclear energy plant and the atmosphere both beneath regular operating circumstances and within the emergency circumstances. The system gives start-up, automatic upkeep of power on the set stage, allows control of vitality distribution alongside the radius and heightwise of the core, compensates for gasoline burn-up, supplies safety of the reactor beneath emergency situations. 24 rods carry out the perform of immediate emergency safequard launched into the energetic zone inside 2.5 seconds beneath definite emergensy conditions. The remaining rods are unified and serve the operate of reactivity scramming, automated upkeep of the reactor power release at the set degree, management of energy distribution over the core radius.
