The nuclear power plantis uninhabitable within a radius of 5 kilometers. According to current regulations, the area within 5 kilometers of the nuclear power plant is a restricted development zone, so villagers near the nuclear power plant will be displaced. It also states that nuclear power plants cannot be built within 10 kilometers of an area where more than 100,000 people live.
The above regulations aim to prevent damage caused by nuclear power leak accidents. During normal operation, you will not be harmed even if you are only 30 meters from the reactor core. Multi-ray shielding must be designed. the nuclear power plant is built. The installation protects the rays inside.
How nuclear power plants work
As we all know, thermal power plants useuse coal, oil or natural gas to produce electricity, hydroelectric plants use water. to produce electricity, and nuclear power plants use nuclear energy. To produce electricity, the basic equipment is the nuclear reactor. The nuclear reactor heats water to produce steam, which converts nuclear fission energy into thermal energy. The steam pressure causes the steam turbine to rotate, and the thermal energy is then converted into mechanical energy. mechanical energy into electrical energy.
What is the sanitary distance between the boilers of thermal power plants and residential areas?
There is radiation. Not harmful to the body.
High voltage lines and substations with voltage levels below 110 kv will not produce so-called electromagnetic radiation, but an induced magnetic field calle extremely low frequency electromagnetic field, which will not be directly absorbed by the human body. like electromagnetic radiation.
The incineration of waste for electricity generation will inevitably produce highly toxic gases and dioxin, an internationally recognized carcinogen. The power plant uses 3T technology, and dioxin emissions are basically less than 0.1 required by European ngTEQ environmental standards. the impact assessment requires that it does not cause air pollution.

Precautions for using portable lamps in thermal power plants:
1. The voltage of portable lights should not exceed 36V, especially when extremely high. wet or surrounded by metallic conductors. When working in local areass, such as inside steam drums, condensers, radiators, evaporators, deaerators and other metal containers or water tanks, the voltage of portable lamps should not exceed 12 V.
2. The power supply for the parking lights must be provided by a portable or fixed step-down transformer. The transformer should not be placed inside the steam drum, combustion chamber, condenser, etc.
3. The high voltage side of the portable lamp transformer must have a plug, and the low voltage side must have a socket, and two plugs that cannot be inserted into each other must be used.
4. The portable light transformer box should have a good ground wire and it is best to use a three-prong plug on the high voltage side.

What is the longest distances remote for heating in a power plant
Design regulations for occupational safety and industrial hygiene in thermal power plants DL 5053-1996
There is no specific distance number, only descriptive provisions.
3 Selection of factory site and general layout of the factory area
3.1 Selection of factory site
3.1.1 Plant site selection should be based on meteorology and geology. , and The main risk factors predicted by natural conditions such as thunderstorms, floods and earthquakes and the impact of surrounding conditions on the factory's work safety and industrial hygiene will be comprehensively examined and preventive measures will be taken into consideration.
3.1.2 The factory site should avoid being adjacent to other factories, warehouses, etc. which present serious fire and explosion risks. LorIf this cannot be avoided, fire and explosion safety distances must be set in accordance with the applicable specifications.
3.1.3 The factory site should be selected on the leeward side of the wind direction at minimum annual frequency for factories with serious risks of air pollution, dust and of poison.
3.1.4 The factory site must be located on the windward side of the minimum annual frequency wind direction in adjacent towns or residential areas. A safety and health protection distance must be established between the factory area and the living area.
Theoretically, in order to ensure the quality of heating, the longest heating distance from the thermal power plant is 15 kilometers.
Heating radius refers to the length of the pipe from the heat source to the farthest user. Generally, the heating radiuse thermal power plants can reach more than 20 kilometers, and the heating radius of. The heating stations in the yard are generally around 500 meters away. The heating radius corresponds to the constructed heat exchange station. Since the head of the circulation pump is determined at this time, the furthest distance over which a certain amount of heating water can flow and return under this pressure is the heating radius.
The meaning of thermal power plant
A thermal power plant refers to a thermal power plant that not only produces electricity, but also uses the extraction steam or steam from exhaust from the steam turbine to provide heat for users. Its main principle of operation is to use thermal power plants for. The hot water generated after electricity production is heated again and then used for heating.
The law does not specify the distance between thermal power plants and residential areas, but generally speaking, the safety distance is at least 300 meters, otherwise there may be radiological interference on the human body and household appliances; , usually thermal power plants The establishment must be examined and approved by the relevant departments, so there is no need to worry too much.
