My analysis of LZ’s so-called safety should be 1. The danger caused by the explosion of the boiler or turbine, 2. The radiation risk of the substation. 3. Chemical/Wastewater Discharge Hazards. 4. Explosion risk between coal bunkers.
1. Boilers and steam turbines have very safe protection interlocking devices. When the steam pressure or medium flow exceeds the balance limit of the boiler or steam turbine, it will stop for protection, so the probability of explosion is very low.
2. There is definitely ionizing radiation, but there is no need to worry about it if you go 10km.
3. As for wastewater pollution, as long as the power plant actually discharges sewage, it cannot escape by flowing the water downstream, but generally the wastewater treatment device of the power plant is necessary.
4. Coal bunkers have very complete operating specifications, and generally they don't, but if an accident occurs, it depends on the amount of coal stored. This depends on the explosion yield and radiation range, which is difficult to determine
