associated witn the fuel-energy corn~lex. The accelerated development of nuclear power envi!laged In our country rs supported by the elaboration andpuTtlng Into operation of 1 and 1.5 mil lion kW reactors. Nuclear power wit I be used also for maintaining central heating In big cities. The construction of a nuclear power station has been started for the combined production of heat and electric power, and a powerful nuclear bolter for supplying a city district with a population of 300i000-400,000 people. These-stations are economic and require practical ty no expensive deliveries of fuel. Beside that, they will not pol lute the atmosphere with harmful exhaust when burning mineral fuel. The uti I lzatlon of fast reactors at power stations Is highly prospective, making It possible to use uranlum-238, the content of which Is much higher In natural uranium raw material than of uranlum-235, which Is used today In reactors at power stations. The program Is very Important for the futher development of the Single electric power system of the USSR. The program envisages the construction of-power I lnes from the East of the country to·tts Centre and to the Urals of 1.150 kV a.c. and 1.500 kV d.c. Electrotechnlcal equipment has been developed for these I lnes with the use of transformers bas~d on power semiconductors. that considerably reduce the weight, overal I dimensions and cost of the equipment, and raise Its reliability. The electric energy, that wll I be supplied via these lines, wll I be generated In the East of the country with the use of cheap coal from major basins, namely, the Kansk-Achlnsk and _Eklbastuz ones. These basins, where the coal Is mined by the most efficient and economic open-quarry method, wll I be equipped In accordance with one of the programs by powerful walking and 
**Analysis**
The text primarily discusses the development of nuclear power and its benefits, including the use of uranium-238, reduction of atmospheric pollution, and the construction of power lines and equipment. It also mentions the use of coal from major basins to generate electricity. These topics suggest that the text is related to the energy sector and its impact on the economy and environment.
