  • "Ensuring Safety and Efficiency: The Essential Role of Surveyors in Nuclear Power"

    In the field of industry, surveyors play an important role, particularly in nuclear power plants. They are involved in various tasks such as checking the shapes and welds of pipelines, measuring the rails of the polar bridge, the loading machine, and various bridges in the reactor building or machine room. They are also responsible for checking the shape, circularity, horizontality, and planarity of the rails, as well as the concentricity and verticality of the Fuel Handling Machine Mast (FHM). This ensures that the machine is compliant and has no defects during fuel loading and replacement. During the replacement of steam generators, which is one of the biggest maintenance tasks for a nuclear power plant, surveyors must follow the replacement of pipelines and the correct positioning of parts with a precision of one-tenth of a millimeter. Much more, they carry out very precise measurements of the positions (altitudes) of various sensors as well as some other precious objects in the reactor building using precise leveling techniques. In summary, surveyors play an essential role in industry, particularly in nuclear power plants. Their expertise and know-how enable them to carry out complex tasks with great precision and rigor. They constantly measure the deformation of the polar bridge, inspect the reactor building and the cooling tower stacks, ensuring the safety and integrity of these structures. #surveying, #metrology, #nuclearpower, #safetyfirst, #qualitycontrol, #engineering, #surveyorlife, #nuclearindustry, #sustainableenergy, #technicalsolutions

  • How does a nuclear power plant works ?

    See more , A nuclear power plant is a complex and sophisticated industrial facility that is designed to generate electricity using nuclear energy. The process of generating electricity in a nuclear power plant is very different from that of a conventional thermal power plant, as it uses nuclear fission to heat water and produce steam that drives turbines. To understand the functioning of a nuclear power plant, it is important to know the main circuits that make it up. Here's an overview of these key circuits : See more... The primary circuit : This circuit is composed of the nuclear reactor, fuel rods, primary pump, pressurizer, and steam generator. The nuclear reactor is where nuclear fission occurs, and the primary pump is used to circulate the coolant through the reactor. The pressurizer is a tank that maintains the pressure inside the primary circuit, and the steam generator turns the hot water into steam. The secondary circuit : This one is composed of the turbine, electrical generator, and condenser. The steam produced in the primary circuit is directed to the turbine, which drives the electrical generator to produce electricity. The steam is then directed to the condenser, where it is cooled and transformed back into water to be returned to the primary circuit. The cooling circuit : Air cooler, component of the cooling circuit. This circuit is used to maintain the temperature inside the nuclear reactor at a safe level. The cooling circuit is composed of a water cooling system, which circulates through the reactor to absorb the heat produced by nuclear fission. The hot water is then directed to a heat exchanger, where it is cooled before being returned to the reactor. In summary, the main circuits of a nuclear power plant are the primary circuit, secondary circuit, and cooling circuit. Each of these circuits plays a crucial role in generating electricity using nuclear energy, and their proper functioning is essential to ensure the safety and reliability of the nuclear power plant.
