The hard "core" force behind zero-carbon heating

Warm a city, a blue sky

We will achieve win-win results in areas such as people's livelihood, environmental protection and economy

In an interview, Ms. Jia, a resident of Haiyang, told reporters that Shandong nuclear Power in promoting the popularization of nuclear energy heating made many residents, including her, very moved: warm a city, a blue sky. "For the first time, I feel that nuclear energy is really linked to the livelihood of our people." Ms. Jia said.

According to reports, after the second phase of the "warm core No. 1" was put into operation, the heating cost of Haiyang citizens was reduced from 22 yuan per square meter to 21 yuan, and they felt the real benefits.

It is not only the citizens who have actually benefited economically.

For the local heat company, before the implementation of nuclear energy heating, they have to buy 180,000 tons of raw coal from Hebei and other places every year, in addition to the investment in coal, transportation, desulfurization and environmental protection equipment and a large amount of electricity consumption. "In the past, the boiler is equipped with desulfurization equipment, and the daily power consumption is five or six thousand degrees, and now the daily power consumption is only about 600 degrees, plus the cost of saving equipment, labor, operation and maintenance, you can save a lot of costs." Fengyuan Heat Co., Ltd. relevant responsible comrades introduced that the former boiler workers said goodbye to the dirty working environment, and the rusty work clothes have been shelved. "The staff work less intensely, the working environment is better, but the income has not been affected at all."

For the Haiyang nuclear power Plant, energy efficiency and resource utilization have also been greatly improved. According to reports, after the first phase of the "warm core No.1" project was put into operation, the thermal efficiency of the whole plant was increased from 36.69% to 37.17%; After the second phase of the project was put into operation, the thermal efficiency increased to 39.94%; After the third phase of the project is put into operation, the thermal efficiency of the unit will be increased to 55.9%, 1.5 times that of the original. If the two units of Haiyang Nuclear Power plant carry out 900 megawatts of nuclear heating at the same time, it is equivalent to using less than 5% of the investment, adding a million kilowatt nuclear power unit.

When it comes to the economics of nuclear heating, Wu Fang believes that "in the long run, nuclear heating will be more affordable than burning fossil fuels."

In his view, based on the price of coal in the last two years plus the transmission cost of a certain distance, the price of using nuclear heating is slightly lower than that of coal heating. However, the price of fossil energy in the future may continue to rise due to production, reserves, and marketization of carbon emissions, and the use of nuclear energy is approximately a one-time investment, and the cost is mainly spent in the construction period. After production, the price of nuclear fuel accounts for less of the cost. Therefore, the cost of nuclear power generation and heating is relatively stable.

However, more eye-catching than the economic account is the environmental account.

Data from Shandong Nuclear Power show that up to now, the "warm core No. 1" project has completed three heating seasons, providing a total of 2.582 million gigajiao of clean heat, reducing raw coal consumption by 230,000 tons, and reducing carbon dioxide emissions by 420,000 tons. Among them, from November last year to April this year, the first heating season after the second phase of the "warm nuclear No. 1" project was put into operation continued to provide stable heating for 143 days, reducing raw coal consumption by about 180,000 tons, reducing carbon dioxide by 330,000 tons, nitrogen oxides by 2,021 tons, sulfur dioxide by 2,138 tons, and soot by 1,243 tons. Compared with the pre-nuclear heating, the PM2.5 in the air during the heating season decreased by 16%, and the good and good weather rate increased by 17%. The heat discharged into the environment has been reduced by 1.5 million GJ, and the regional Marine ecological environment has been significantly improved.

Safe, economical, clean, efficient... Haiyang nuclear heating has taken the first step of comprehensive utilization of nuclear energy in China. It is understood that as the largest nuclear heating project in China, the heating capacity of "warm core No. 1" accounts for more than 90% of the total national nuclear heating capacity.

In addition to Haiyang in Shandong province, the first nuclear heating project in northeast China, the Hongyanhe Nuclear heating demonstration project, also officially put into operation in November this year, covering Hongyanhe Town, Wafangdian City, Dalian City, Liaoning Province, benefiting nearly 20,000 local residents. Last year, Qinshan Nuclear Power Plant and Zhejiang Haiyan jointly built a nuclear heating demonstration project, creating a precedent for nuclear heating in southern China, and China's first nuclear industrial heating project was recently put into use.
