Advantages:

1, clean green. Nuclear energy is green and clean energy, and there is no emission of carbon dioxide and sulfur dioxide. For heating provinces, it is of great significance to replace coal burning with clean energy.

2. stability. Compared with hydropower, photovoltaic and wind power, nuclear energy is a clean energy that can replace fossil energy on a large scale. Moreover, among all the utilization costs of nuclear energy, its fuel cost accounts for a very low proportion, which is not easily affected by the external environment, and its utilization cost is more stable than other fossil fuels.

3. efficient. For heating enterprises, after using nuclear energy for heating, the original boilers and environmental protection equipment are no longer used, and the nuclear energy heating station is unattended, which not only saves electricity, maintenance, environmental protection and labor costs, but also has long service life and good economy.

Disadvantages:

1. Strict site selection criteria: For safety reasons, large commercial nuclear power plants are restricted by a series of strict standards in the process of planning, site selection and construction. The site should be located as far away from big cities as possible with relatively low population density.

2. The first nuclear energy project and the economy of summer operation: nuclear energy heating has the problems of high project investment and low operation economy. Financial indicators are difficult to meet the requirements of internal rate of return. The nuclear heating project has no heating load and cooling load in summer, but only unstable industrial gas load, which is a severe test for the stable operation of nuclear energy projects.

3. Public acceptance of nuclear heating needs to be improved: after more than 30 years of development, nuclear heating technology is no longer a problem, and public acceptance of nuclear heating has become an important obstacle to the landing of its demonstration projects and industrial promotion.

Which areas of China have achieved nuclear heating;

202119, the second phase of the national energy and nuclear heating commercial demonstration project of the national power investment "Warm Nuclear No.1" was officially put into use in Haiyang City, Shandong Province, and all the urban areas of Haiyang City will realize nuclear heating.

2021111,the first phase of the Qinshan nuclear power heating energy-saving demonstration project of China National Nuclear Corporation was completed, and the heating trunk line began to be filled with water, entering the stage of internal and external system joint debugging.

According to the schedule, from the end of 202 1 and1to the beginning of 65438+2, the heat energy provided by Qinshan nuclear power will enter the local residents in Haiyan county, and the Jiangnan nuclear energy heating demonstration zone has begun to take shape. The overall goal of the project is that by 2025, the nuclear heating area will reach 4 million square meters, covering the main urban area of Haiyan County.

In addition, small modular heating reactors and large cogeneration nuclear power projects in Heilongjiang, Jilin, Liaoning and other places are also carrying out the preliminary work of the projects.
