Create clean water thanks to the waste heat of nuclear power plants

Nuclear desalination is the use of heat from nuclear reactors to evaporate seawater and condense pure water. In the essay on nuclear desalination in the Internetional Journal, the Indian and Italian groups have argued that despite the community's concerns, the process's convenience and low energy costs will for methods become a preferred option.

Picture 1 of Create clean water thanks to the waste heat of nuclear power plants Having a ready supply of clean water is a human right, but access to safe fresh water is becoming an increasing difficulty that can be achieved in many parts of the world. Climate change issues and population growth are creating new pressures on water resources. Brackish water and salt water desalination by reverse osmosis is expensive and ineffective. Marco Rognoni, expert of salt of Galarate, Italy and colleagues MPRamaswamy and J.Justin Robert Paden in Tiruchirappalli, India, have calculated the cost balance and demonstrated that atomic evaporation desalination benefits more than conventional reverse osmosis.

The selection of appropriate desalination technology between reverse osmosis and evaporation is based on a number of factors, including investment costs, maintenance costs, availability, responsibility burden and degree requirements. Pure water after desalination. However, the main factor is usually the operational cost of the plant, especially the cost of energy consumption.

Input energy accounts for about 35-45% of the total cost of producing desalinated water using reverse osmosis, in which seawater is pressed under pressure through a semi-permeable membrane, a filter for The ion salts the water trapped behind and creates pure water on the other side of the membrane. However, energy costs are increasing as environmental pressures on reducing greenhouse gas emissions are demanding sustainable and alternative energy sources for industrial processes.

Typically, evaporation desalination is considered ineffective because it requires twice the energy. However, Rognoni and colleagues recalculated the energy needed to participate and suggested that this is not just an estimate. Previous calculations are not based on the performance of water purification but rather on the energy loss of the steam turbine. Scientists also point out that abundant heat energy is a byproduct of atomic energy generators, so steam desalination can become the best application to produce fresh water. .
