[Observer Network Comprehensive Report] On the eve of the SCO Qingdao Summit, China and Russia recently signed the largest nuclear power cooperation project to date, with a total contract value exceeding 20 billion yuan and a total project cost exceeding 100 billion yuan.

Among them, some units originally scheduled to use American technology have now switched to Russian technology, which has surprised the industry.

According to the news released by CNNC on the 8th, CNNC and Russian National Atomic Energy Group signed the Framework Contract for Unit 7/8 of Tianwan Nuclear Power Plant, the Framework Contract for Xudabao Nuclear Power Plant and the Framework Contract for Equipment Supply and Service Procurement of China Demonstration Fast Reactor in the Great Hall of the People, witnessed by the Supreme Leader of president, China and Russian President Putin.

This is by far the largest nuclear energy cooperation project between China and Russia. The total amount of the above-mentioned package contracts exceeds 20 billion yuan, and the total project cost exceeds 100 billion yuan.

20 billion nuclear bills, this move by Russia surprised the industry.

These three contracts correspond to three projects, including five nuclear power units. Among them, Xudabao Nuclear Power Station is located in Huludao City, Liaoning Province, and is developed by China National Nuclear Corporation Liaoning Nuclear Power Company, which is controlled by China National Nuclear Corporation. The plan has not yet started, and it is planned to build six million kilowatt nuclear power units.

The first phase of the Xudabao nuclear power plant has two units.Previously, it was decided to adopt AP1000 technology designed by Westinghouse.The world’s first AP1000 nuclear power unit is currently located in Sanmen Nuclear Power Project, Zhejiang Province, and is also purchased from Westinghouse. Caijing magazine quoted people familiar with the matter as saying that the main equipment needed for the first phase of Xudabao Nuclear Power Station had already been ordered. According to the convention, the same technical route is generally adopted at the same site, so all six units of Xudabao Nuclear Power Station will adopt AP1000 technology.

But according to this contract,Tianwan and XudaFort cooperation project will adoptfourTaiwan and RussiaVVER-1200Type iii nuclear power unit.China and Russia will cooperate in equipment supply and technical services in the demonstration fast reactor project in China.

In this regard, Caijing reporters learned from many sources that the AP1000 technology will not be changed for two units in the original phase I project, and the new VVER units will be applied to units 3 and 4 in the second phase of Xudabao.This also means that Russia was able to grab the original target market of Westinghouse.Some insiders also told Caijing that the possibility of starting the second phase of Xudabao before the first phase of the project is not ruled out, and it is even very likely that this arrangement will be made.

In addition to the Xudabao nuclear power plant mentioned in the contract, Tianwan nuclear power plant is located in Lianyun District, Lianyungang City, and eight million kilowatt pressurized water reactor nuclear power units are planned to be built at the site. Russian AES-91 nuclear power units are used in the first phase project No.1 and No.2 and the second phase project No.3 and No.4, which are high-tech cooperation in the field of nuclear energy under the promotion of deepening political mutual trust, developing economy and trade and strengthening international strategic cooperation between China and Russia, and are the landmark projects of Sino-Russian nuclear energy cooperation. The construction of Unit 5 was officially started in December 2015, which became the final work of newly-built nuclear power units in China during the Twelfth Five-Year Plan period.

Finally, the fast reactor project refers to the demonstration project of Xiapu fast reactor in Fujian. The so-called "fast reactor" is the abbreviation of "fast neutron reactor". Fast reactor nuclear power technology is called the main reactor type of the fourth generation advanced nuclear energy system. It can increase the utilization rate of natural uranium resources from about 1% to over 60% at present, and minimize radioactive waste, which can solve the problems of depleted uranium resources, low utilization rate of nuclear materials and difficult disposal of nuclear waste in one fell swoop.

On December 29, 2017, CNNC announced in Xiapu County, Fujian Province that the civil construction drawing of the demonstration fast reactor project was from CNNC.

Recently, Liupanshui, Guizhou

A female college student cleans the dormitory.

Because oxalic acid bought online reacts with washing powder.

Collective poisoning of roommates

According to classmate Tian, the dormitory was swept out of worms, so she bought oxalic acid online for cleaning, and also brushed the floor with washing powder. After closing the door and sleeping, the two gases reacted, and four people were poisoned and became dizzy and vomited. At present, the symptoms have been alleviated.

Many netizens said

Don’t fool around if you don’t know chemistry.

Some netizens said

After cleaning, you must open the window for ventilation.

There are also some netizens reminding me.

Never use two kinds of detergents together.

Many people are doing cleaning.

Often in order to pursue cleanliness, cleanliness, sterilization and so on.

Will use a variety of disinfectants and detergents at the same time.

But pay attention.

Many disinfectants and detergents cannot be used at the same time.

You only need to use a single one when you use it.

in recent years

So news of poisoning happens from time to time.

The most accidents in the news are the mixture of 84 disinfectant and toilet cleaner. According to the doctor, when 84 disinfectant meets toilet cleaner, it will produce irritating gas, mainly chlorine. Different concentrations of chlorine have different effects on human body, and the concentration is too high or life-threatening. For example, in an environment with small area and poor ventilation, the chlorine concentration produced after using 84 disinfectant and toilet cleaning forest is high, which will affect human body in just a few minutes and damage human skin and mucosa, such as irritating eyes and nose, causing severe cough, chest tightness, tight breath, difficulty breathing and so on. If the inhaled chlorine concentration reaches 120-180mg/m3; , it will cause serious damage to human body, and the chlorine concentration reaches 300 mg/m3; When inhaled, it may cause fatal injury.

Toilet cleaner can’t be used together with 84 disinfectant.

Toilet cleaner can’t be used together with Tianna water.

Tianna water, also called banana oil, is a colorless, transparent and volatile liquid, which has the functions of cleaning, dilution and emulsification, and is generally used for cleaning. Tianna water is a mixture of various organic solvents, mainly toluene and xylene, which can be brought into human body through skin and respiratory tract after volatilization. Xylene mainly inhibits the central nervous system of human body, showing dizziness and chest tightness. After inhaling high concentration for a short time, the anesthetic effect on central nervous system and autonomic nervous system and the stimulation effect on mucosa may be accompanied by liver, kidney, heart, lung and other organ damage.

When cleaning the home,

When using various cleaners and disinfectants

We should do the following.

1. Choose carefully: according to the object to be cleaned, choose the appropriate detergent. Acid cleaners and alkaline cleaners cannot be mixed.

2. Dilute and wear a mask before use: All kinds of cleaners and disinfectants should be used after dilution in strict accordance with the dilution ratio listed in the instruction manual. At the same time, it should be noted that masks should also be worn and protected when diluting.

3. Label: The diluted detergent and disinfectant should be labeled on the bottle body, and the name and purpose should be clearly written to prevent confusion.

4. Pay attention when using: When using various cleaners and disinfectants, pay attention to wearing protective equipment, such as masks and face screens. At the same time, you should also choose suitable cleaning tools, and you must not operate by hand.

5. Return to the original place after use: After using each cleaning agent and disinfectant, cover the lid and store it in the designated place to avoid taking it by mistake and avoid eating it by children or pets at home.

Xiaobian reminds me here

Cleaning is certainly a good thing.

But also pay attention to the methods.

Don’t try to

Pursue cleanliness and sterilization blindly.

And various disinfectants and detergents are mixed.
