Recently, experts from the Science Popularization Department of the Chinese Association of Science and Technology and the Chinese Nuclear Society wrote that this year, severe haze weather broke out again in most parts of central and eastern China, affecting an area of about 1.43 million square kilometers, accounting for about 15% of the land area. Of the 161 cities that have carried out the monitoring of new air quality standards across the country, 36 cities have suffered severe pollution and above, which seriously affected the health of the people.
In September last year, the State Council issued the "National Ten Articles" on air pollution prevention and control, and proposed the national and key regions (Beijing-Tianjin-Hebei, Yangtze River Delta, and Pearl River Delta) PM2.5 / PM10 reduction targets and 10 measures for prevention and control in the next five years. . The core prevention and control measures in the energy field are to control the total coal consumption, increase the use of natural gas, and vigorously develop alternative energy sources such as nuclear power and renewable energy.
Experts point out that according to calculations, if 10 million kilowatts of nuclear power installed in the surrounding areas of Beijing-Tianjin-Hebei, the Yangtze River Delta, and the Pearl River Delta, respectively, or 10 million kilowatts of nuclear power will be delivered to the region through external power transmission, PM2 in these regions can be .5 annual average concentrations decreased by 3.4 μg / m3, 1.7 μg / m3, 4.0 μg / m3, equivalent to reducing the annual average PM2.5 concentrations in these three regions by 3% and 2.5%, respectively, on the current basis And 9%. Five years later, these nuclear power installations contributed 12% (about 1/8), 12.5% (1/8), and 60% of the local average annual concentration reduction of PM2.5.
According to experts, compared with hydropower, wind power, and solar power, nuclear power has obvious advantages in improving environmental quality. Nuclear power has a large stand-alone capacity, stable operation, high utilization hours, and can be used as the base load of the power grid. The production process has basically zero emissions to the environment, and the effect of improving the environment is very significant. It is estimated that for every 40 million kilowatts of nuclear power built, it can replace standard coal consumption of 100 million tons per year. The substitution effect of 1 million kilowatts of nuclear power on standard coal is equivalent to 2 million kilowatts of hydropower, 3.5 million kilowatts of wind power, and 4.7 million kilowatts of photovoltaic power (measured according to the annual utilization hours of nuclear power 7000, hydropower 3500, wind power 2000, and photovoltaic power generation 1500) .
