ROOPPUR NPP LIKELY TO BE HIGHLY DERATED26 Sep 2025 21:50
😂…no really you can’t make this ****e up……it now turns out the most expensive inland energy project ever in bangladesh was designed to run in cold siberian climate so will be sucking electricity from the grid of bangladesh just to keep running when it’s fkn hot….oh and it gets really hot in bangla….😂….is this news to those that signed this off??….
so what i’m getting at is once again all roads lead to the best coal in the world in the best super power plants in the world
the vver-1200 model has been designed for cold countries like russia, where cooling water below 20°c is naturally available at sea, lakes, and rivers. the nominal capacity of 1,200 mw is based on cold weather conditions. bangladesh is a hot country, and so the capacity will be reduced.
effect of hot weather in bangladesh
the ambient temperature in ishwardi reaches 40°c during the peak summer. the river water temperature also becomes very hot. the cooling water temperature after evaporative cooling in cooling towers will be 32°c, and that at the condenser inlet will be 33°c, which is 15°c higher than the design temperature of 18°c. as a result, the turbine will miss the output involved in this 15-degree range. the plant will not be able to reach the nominal capacity. a research paper states that capacity will decrease by 0.444% for a 1-degree increase in water temperature. thus, for hot weather, each unit of the rooppur power plant will be de-rated by about 80 mw.
borrowing of electricity from the national grid
unlike conventional nuclear power plants, the vver-1200 cannot drive its auxiliaries by bleeding its own steam. it has to borrow electricity from an external source. there are huge water pumps and powerful motor-driven valves in the primary and secondary loops. additionally, the circuit contains numerous control unit assembly drives, ventilation units, and pumps, all of which require electrical power. to run auxiliary drives, the plant will draw 120 mw from the grid, and the generated power will be adjusted accordingly.
