65 years, China's nuclear industry is moving from a big power to a daily life.
[2020-01-31]

Nowadays, nuclear technology has entered people's life, and has been widely applied in industry, agriculture, medicine, environmental protection and other fields. In the process, people are constantly changing their views on nuclear.

The nuclear industry has always been closely linked to the fate of the motherland and is an important cornerstone of national security.

January 15th this year was the 65th anniversary of China's nuclear industry. Over the past 65 years, China's nuclear industry has realized the development of nuclear power independence, serialization and scale in the aspects of atomic bombs, hydrogen bombs and nuclear submarines. "Now, nuclear technology has entered people's lives, and has been widely applied in industry, agriculture, medicine, environmental protection and other fields." Liu Baoshen, a nuclear technology Commissioner of China National Nuclear Group Co., Ltd., said, "in the process, people are constantly changing their views on nuclear."

Technology continues to improve, nuclear discoloration is no longer necessary.

According to Liu Baoshen analysis, before people "talk about nuclear discoloration", mainly from the atomic bomb, hydrogen bomb and other destructive weapons powerful power and the terrible consequences of the explosion. For example, Hiroshima and Nagasaki, Japan, had experienced atomic bomb bombing, resulting in many years of grassland failure and lack of human presence. The Fukushima nuclear leakage accident in Japan further aggravated people's "fear of nuclear" mentality.

"In the final analysis, these fears can be interpreted as a lack of understanding of nuclear energy and a lack of understanding of energy." Liu Baoshen said, "many people feel that nuclear power is dangerous. They often ask such questions:" since we have other sources of energy, why do we need to use nuclear energy? " What they do not know is that the application of nuclear energy has gradually become safe in the process of development. "

Liu Baoshen took Fukushima nuclear leakage accident as an example, pointing out that the accident was caused by the fact that the hardware and equipment of nuclear power plants had not been updated, maintained and followed up for a long time, and the safety awareness was not strong enough. "We can not hold a completely negative attitude towards nuclear power because of an accident. With the upgrading of supporting measures and means, and the continuous improvement of the safety performance of nuclear products, nuclear power will become more apparent than other energy sources.

Nuclear energy is less invested, more productive and stable enough to win the clean energy such as wind and solar energy. From the point of view of atmospheric environmental protection, the superiority of nuclear energy makes it difficult for other energy sources to be right, such as the greenhouse gas and harmful gases generated by nuclear power generation are far lower than other power generation methods, and the suspended particles produced by nuclear power generation are almost none.

"Nuclear power is like a powerful" magic seed "that needs constant control and correction in its growth process. In the process of nuclear energy unceasing security, we need to give enough time and support to nuclear power, and we need to give it more patience and confidence. " Liu Baoshen said.

Widening nuclear products and deepening people's lives in applied fields

In addition to nuclear power and nuclear weapons, nuclear technology has a broader but not well known "weapon". "If nuclear power and nuclear power are regarded as" heavy industries "in the nuclear field, the non dynamic nuclear technology such as isotope and 188体育官网 technology is the" light industry "in the nuclear field. Liu Baoshen's analogy.

When it comes to sterilization, people often think of all kinds of potions or ultraviolet rays. In order to kill anthrax, a self shielded electron beam 188体育官网 sterilizer has been developed in China. The accelerator electron gun emits high power nuclear electron beam. When the irradiated object on the conveyor belt passes through the high-energy electron curtain 188体育官网 area, the biological bacteria in the 188体育官网 objects will be killed completely, and the treated articles will not remain any radioactive.

Nuclear technology based tracer technology uses radioisotopes as tracers to understand physical and chemical changes that people can't see or feel. At present, tracer technology has played an important role in many fields such as chemical industry, petroleum, water conservancy and so on.

Our country spends tens of millions of yuan on dredging of the Changjiang Estuary every year. In order to understand the operation rules of sediment, technicians put quartz sand containing scandium -46 isotopes in the upper reaches of the Yangtze River, and then use the scintillation detector to observe and observe, providing important technical data for the treatment of the Yangtze Estuary Deepwater Channel and the construction of the all-weather and deep water channel. After adopting this technology, the one hundred thousand ton freighter can reach Shanghai Baoshan steel wharf directly through the Yangtze River Estuary.

What is more surprising is that nuclear technology has been integrated into modern agricultural science and technology in recent years, and has become one of the most important technical means to support agricultural development. The most important thing is the technology of food ir188体育官网. It is a new food processing technology after food storage, heating and freezing preservation. Since 1984, China has begun to irradiate garlic, potatoes, onion, sweet potato wine and meat products. At present, more than 200 units in 28 provinces, municipalities and autonomous regions have carried out research on ir188体育官网, preservation, sterilization, and quality improvement of over 200 kinds of food. The state has approved 18 kinds of irradiated food to be listed, and the total annual irradiated food amounts to 100 thousand tons, ranking first in the world.

In the medical and health field, proton therapy for nuclear technology is based on the accurate transmission characteristics of proton beams, which is "tailored" for the treatment of patients. The precise location of the 188体育官网 dose is located in the tumor position through a precision instrument, as if the "deep water bomb" was "fixed point blasting" when reaching a certain depth to the target.

In addition, nuclear technology can also be applied to the field of radiopharmaceuticals manufacturing. At present, a whole set of R & D system of radiopharmaceuticals has been formed in China.

Nuclear safety has always been placed first in China.

In the autumn of 1954, a piece of uranium ore from Guangxi was brought into the Zhongnanhai, which is known as the "stone of opening" for our nuclear industry.

From nuclear weapons, nuclear submarines to nuclear power, from national defense construction to serving the economic and social sectors, over the years, China has gone out of a way of developing nuclear industry with Chinese characteristics, and has always placed nuclear safety in the first place.

Over the past 65 years, China has never experienced nuclear safety incidents at level two or above. Nuclear materials have maintained a safety record of "one gram does not lose a lot", and have maintained a leading position in industrial safety. Their experience and achievements have also made outstanding contributions to the development of the world's nuclear industry.

In September 3, 2019, the Information Office of the State Council published the white paper on China's nuclear safety. It introduced the course of development of nuclear safety in China, the basic principles and policies, regulatory principles and practical experience of nuclear safety, and expounded China's determination and action to strengthen international cooperation in nuclear safety and promote nuclear safety.

China always adhered to the nuclear safety strategy of "safety first", and promoted the mutual promotion of the two objectives of development and security. Under the overall framework of the five year plan for national economic and social development, the nuclear safety plan was formulated and implemented every 5 years. What is being implemented is the "13th Five-Year plan" for nuclear safety and radioactive pollution control and the long-term vision for 2025. This plan analyzes the situation and tasks of nuclear safety in China, expounds the guiding ideology and basic principles of nuclear safety, and defines the objectives, key tasks and key projects of nuclear safety, which are the general principles of the 13th Five-Year nuclear safety work.

In addition, China is also actively promoting international nuclear security cooperation and establishing an international cooperation system for nuclear safety.

In recent years, China has acceded to the International Atomic Energy Agency and the United Nations all international conventions on nuclear safety, including the Convention on nuclear safety, the early notification of nuclear accidents, etc., fulfilling its obligations under the international convention, and actively participating in exchanges and cooperation, and establishing close ties with the United States, France, Russia and other emerging nuclear power countries along the belt. More than 50 nuclear safety cooperation agreements have been set up to enhance expert exchanges, technical cooperation and high-level visits.

Relying on the national R & D base for nuclear and 188体育官网 safety supervision technology and the China Nuclear Security Center, China will provide a platform for developing countries to carry out nuclear safety related training and exchange activities, enhance national security level, security capability and share China's security experience. Through these efforts, the global nuclear safety level has been effectively promoted continuously and continuously.
