Hongyanhe Nuclear Power Station is the first one-kilowatt nuclear power station started construction during China's “Eleventh Five-Year Plan†period, and the first million-kilowatt nuclear power station in Northeast China. It is the key support project for the second-generation nuclear power independent construction in China. In accordance with the requirements of the National Development and Reform Commission, the development of four units in the first phase of Hongyanhe River will basically realize the autonomy of the second generation of improved nuclear power equipment with a kilowatt level.
As a key equipment in PWR nuclear power plants, nuclear reactor pressure vessels are closed vessels that place nuclear reactors and withstand enormous operating pressures. They have the characteristics of high manufacturing technology standards, high degree of difficulty, and long cycle time. They are non-replaceable equipment and must ensure the life of nuclear power plants. It is absolutely safe and reliable during the period.
Since the launch of this project, China has meticulously organized the project as a model product for enterprise restructuring, product transformation, and transformation of economic development methods. It has configured all parties’ superior resources and implemented all aspects in terms of technology research and development, production organization, quality supervision, and schedule progress. Process control ensures that everything is safe.
It is understood that China has established itself as an independent innovation company and has concentrated on its strengths. In the development process, it has produced a large number of industrial and auxiliary tools, conducted a large number of tests and process assessments, and successively conquered the compaction, quenching, and grain refinement of large-scale thick-walled forgings. And the homogeneity, integration of the forging section forming forging, saddle fitting section welding, neutron flux tube hole processing and other technical difficulties, created a number of China's nuclear power equipment manufacturing history, a number of first.
With the rapid development of China's nuclear power industry in recent years, more advanced second-generation and third-generation nuclear power projects have started construction in China. Due to the large amount of demand, large-scale castings and forgings required for key nuclear power equipment have become the bottleneck restricting the rapid development of China's nuclear power industry. Import from abroad is difficult to meet the demand and there are barriers to the introduction of technology, which seriously affects the construction process of China's nuclear power plants.
To reverse this situation, China, as a leading manufacturer of heavy equipment manufacturing in China, has been engaged in research and development of nuclear reactor pressure vessels for many years. It is committed to the development and application of nuclear power products' own technologies and nuclear special technologies, and promotes them in long-term production practices. The localization of nuclear power has accumulated rich experience.
Since 2006, "China's key large-scale manufacturing technology for nuclear power equipment, large-scale castings and forgings," "the development of nuclear power equipment, large-scale forgings," "AP1000 pressure vessel manufacturing technology," and other national key issues have been established, China has a large number of key development tasks. . In accordance with the deployment, it focused on its strengths and focused on the three main lines of scientific and technological breakthroughs, technological transformation, and manufacturing qualification certification. It carried out technical research on localization of key equipment for the second generation of improved and third-generation nuclear islands and continued to make breakthroughs.
At present, China has been at the leading international level in the development of nuclear reactors such as nuclear reactor pressure vessels and nuclear islands.
How to solve the harm of too dry indoor air
If the indoor air is too dry, it will make people feel very uncomfortable. It will not only affect skin health, but also have a certain impact on visceral health. Therefore, when you feel that the indoor air is dry, you must find a way to solve it in time. How to solve the indoor air drying?
If the indoor air is dry, you can put some plants. You should choose tiger tail orchid, aloe or Chlorophytum, which can release oxygen at night. Don't put too much in the bedroom. You can sprinkle some water on the leaves of plants. In order to solve the problem of indoor air drying, you can put a basin of water in the room, cover a wet towel on the radiator, or put a basin of water in the room, and you can also drag the floor with a mop to make the ground moist. In this way, you can solve the problem of too dry air, and this method is relatively healthy, There will be no harm. If the indoor air is too dry when using the humidifier, you can also use the humidifier Aroma Diffuser. This is a relatively simple method. You can put pure water or cool it in the humidifier. It should be replaced every day. It should be cleaned after about two weeks of use. Do not add essential oil or bactericide indiscriminately in the humidifier. After entering the body, On the contrary, it will have an adverse impact on health, which is easy to cause bronchitis and lung diseases. Indoor drying of wet clothes to solve the problem of air drying, you can dry wet clothes indoors, which can also increase the humidity. If some clothes are not in a hurry, don't dry or dry them directly. Put them indoors and let them dry naturally, so that the humidity in the house can be improved a lot.
Indoor air drying is harmful. There are many air drying bacteria, which are easy to have a great impact on the respiratory system. Moreover, the water loss in the body becomes faster, and the speed of skin aging will naturally become faster, so wrinkles will appear on the face.
What fruit do you eat when the air is dry
Hawthorn indoor air is dry, and the water loss rate in the body will be accelerated. To solve this problem, eating some Hawthorn appropriately can achieve very good results. It can improve appetite, help digestion, reduce blood lipids, activate blood vessels, supplement the water needed by the body and make the body metabolism faster. Apples are rich in nutrients, which can make the skin more lubricated. Eating more apples when the indoor air is dry can keep the skin moist. Banana indoor air is dry, you can eat some bananas appropriately, and it is rich in potassium, so it can maintain better skin health, effectively solve the skin problems caused by drying, and discharge the stool more quickly. The sour and sweet taste of grapefruit grapefruit is very good, and it can clean up the intestines and moisten the lungs. It can make the food digestion faster. The effect of relieving cough and resolving phlegm is very good, and it can also improve the appetite.
