Nuclear reactor<\/strong><\/p>\n The differentiation between nuclear powerplants is based on the type of the super system, which is the nuclear reactor. The plant located in the city of Brunsb\u00fcttel operates using an advanced gas-cooled reactor.<\/p>\n Design <\/strong><\/p>\n The main components of this reactor\u2019s type, as displayed in the figure above, are as follows:<\/p>\n Due to the complexity of the superstructure with its many components, a major part of this structure had to be selected for life cycle analysis, which is the nuclear core.<\/p>\n Geometry<\/strong><\/p>\n Height:\u00a0 23.7 m<\/p>\n Diameter: 4.8 m<\/p>\n Total Area: 18 m\u00b2<\/p>\n Number of fuel rods: around 332 rods<\/p>\n Materials<\/strong><\/p>\n Throughout the life cycle analysis, three different design parameters were distinguished as important aspects in building maintenance strategies and eventually reliable optimization methods. These aspects are:<\/p>\n Moderator:<\/span> The main material of this component is graphite<\/strong>. The function of graphite is to slow down the neutrons released during nuclear fission processes.<\/p>\n Maintenance interventions<\/strong><\/p>\n The typical maintenance scheme of advanced gas cooled reactor consists of different preventive and corrective maintenance activities. Capturing all these interventions in one scope could be quite challenging, especially for planned data fusion with four different civil systems (Wind Farm, Railway System, Lift bridge, and a Truss Bridge). Therefore, with a lifetime of 60 years<\/strong>, three major interventions were considered as follows:<\/p>\n Description<\/span>: In-situ turbomachine maintenance will be performed during scheduled plant outages, when possible, because the reactor must be shut down and the PCRV (prestressed concrete reactor vessel) depressurized before anyone can enter the vessel. The shielding requirements have been established to give a radiological environment in the turbomachine bearing cavity areas conducive to personal access.<\/p>\n Intervals per years: Every 7 years \u00a0<\/strong>Description<\/span>: Inspection process happens mainly in tubes of the steam generator. These processes are critical to the safe and economical operation of nuclear power plants. Often, different characteristics of the damage (corrosion, cracking, fatigue, etc.) require different types of inspection tools. A shutdown of the plant depends on the severity of the damage happening in or outside these tubes. For example, a detectable leakage of tubes exceeding 10 kg\/h would require a shutdown until corrective measures take place.<\/p>\n Intervals per years: every 10 years \u00a0<\/strong>Description<\/span>: These interventions occur relatively rarely since the reactor\u2019s core is constantly monitored and data is being transmitted throughout important nuclear activities (refueling). In other words, core inspection or testing is a predefined maintenance activity that includes a remote checkup on the graphite bricks of the core. This procedure is carried out using cameras and robotic materials in order to avoid radiation exposure. It ensures the integrity of the graphite structure where potential cracking is pound to occur due to frequent nuclear fission processes and oxidation. A complete shutdown is planned for such activity.<\/p>\n Intervals per years: every 25 years \u00a0 REFRENCES:\u00a0<\/strong><\/p>\n <\/p>\n \n","protected":false},"excerpt":{"rendered":" The nuclear power plant is located on the west coast of the Dithmerschen area of Schlweswig-Holstein on the banks of the lower Elbe.
