Chapter 630 Generation 1.5

Namtso Nuclear Power Plant.

Through the deserted passages, buildings made of super materials, if they are residential buildings or commercial buildings, may undergo secondary interior decoration.

But similar to industrial buildings, especially underground base-type buildings, they basically maintain their initial state.

The silver-gray walls and ceiling are also pure white, and the air outlet of the constant temperature air conditioner blows a wind of 26 degrees Celsius.

Huang Weichang is extremely familiar with this architectural style and minimizes secondary decoration of the interior. This is a consistent style of industrial architecture.

Ai Yanmin, the manager of the nuclear power plant, is an old-fashioned and serious person. He took Huang Weichang and his party to the main control room of the nuclear power plant.

The Namtso Nuclear Power Plant has been in trial operation for more than two months and is currently operating very well. The plant has a total of three Tanggu 1.5 nuclear fusion systems installed.

"...Mr. Huang, Unit 1 and Unit 2 are currently operating normally, and Unit 3 is undergoing final installation." Ai Yanmin pointed to the nuclear power plant floor plan in the main control room.

Huang Weichang glanced at it.

On the plan view of the nuclear power plant, the three sets of nuclear fusion generator sets are not crowded together, but are 1.3 kilometers apart and distributed in a line along the mountain.

Among them, Unit 1 and Unit 2 are common units, and Unit 3 is a peak-shaving and backup unit. The power generation power of a single nuclear fusion generator unit is 8,000 megawatts.

After reading some information, Huang Weichang looked up and asked: "I heard that the size of the improved unit has been reduced a lot?"

Ai Yanmin nodded: "Yes, compared with the original unit, the size is reduced by about 24 to 27%, and the power and efficiency are significantly improved."

To evaluate the power, Huang Weichang combined the current electric energy needs for indoor agriculture in snowy areas.

The total power of the three sets of nuclear fusion power generation units is 24,000 megawatts. Taking into account peak shaving and backup, the average power should be around 20,000 megawatts.

The annual power generation can reach 175 billion kilowatt hours, which is equivalent to 1.7 Three Gorges Hydropower Stations.

The advantage of the nuclear fusion power station is that after continuous technological improvements, an internal circulating water system is adopted. The fresh water replenished by the steam turbine at one time can be recycled for a long time.

The average monthly hydration rate is about 2.1 to 3.4%.

Huang Weichang then asked: "Lao Ai, how to deal with the cooling water of the power station?"

"Currently it is mainly used for internal heating of the base and heating of nearby villages and towns, and the rest is temporarily released to Namtso." Ai Yanmin then added:

"About 5 kilometers away from the base are the Namtso indoor agricultural factory, fresh water plant, salt factory, and then the town of Namtso. The agricultural factory has not yet been put into use. Once put into use, cooling water will be in short supply."

Nuclear power plants produce cooling water, which is inevitable.

Because according to thermodynamics and energy conservation, no matter how high the thermal efficiency of a nuclear power plant is, it cannot achieve 100% thermoelectric conversion.

Even with a thermoelectric power generation system, the overall thermal efficiency of controllable nuclear fusion is still at the limit of 75.1%. It is difficult to continue to improve thermal efficiency at this stage.

Therefore, during the power generation process, part of the energy will be discharged in the form of waste heat, of which cooling water accounts for the majority.

Although this cooling water can be used with a thermoelectric power generation module and a supplementary heating furnace for secondary waste heat recovery.

However, engineers chose to abandon this design, because the economic benefits generated by this waste heat secondary power generation system may take decades to recover the equipment cost, and the efficiency can be improved by up to 1 to 2%, which is very cost-effective. It's too low.

After primary waste heat power generation, it is difficult to use the heat of the cooling water to directly use the temperature difference to generate electricity again. It must be supplemented with heat to increase the temperature to reach the temperature standard for secondary power generation.

The supplementary heat must be added from an external system, which will cause the system to become bloated.

As for circulating cooling water into the steam turbine, this approach is not worth the gain, because higher-temperature saturated steam is not allowed to enter the steam turbine. This not only fails to improve efficiency, but will reduce efficiency and even cause power generation fluctuations.

Instead of the thankless waste heat secondary power generation, it is better to directly transport the cooling water out to heat nearby areas.

Huang Weichang knew the reason why the Suiren Department set up the nuclear power plant here.

Namtso is a plateau saltwater lake and the second largest saltwater lake in the country. It has a freshwater purification plant, a lake salt plant, and a large lakeside plain. It is surrounded by tall mountains and is a vast and sparsely populated area.

Although Namtso seems vast and sparsely populated, the Nyenchen Tanglha-Namtso Tunnel has been opened and is only about 40 kilometers away from Damxung City, the hub city of the Qinghai-Tibet Railway.

There is a branch line of the super highway, and the transportation between the two places is very convenient. It takes about half an hour to drive.

The electricity output from the nuclear power plant cannot be digested by Namtso alone. In addition, there are fresh water, salt, chemical raw materials, construction salt (filler for super materials), and agricultural factories built in the future, which will output a large amount of food, vegetables and fruits. .

According to the plan, Xueyu District and Qinghai will build six controllable nuclear fusion power plants between 2016 and 2021, increasing the annual power generation capacity of local nuclear power plants to 1.2 trillion kilowatt hours.

If calculated based on the population of the two places, the per capita power generation here will reach an astonishing level.

The combined population of the two places is less than 9 million. By around 2021, the total annual power generation will reach 1.3 trillion kilowatt-hours (plus other hydropower, solar energy and geothermal energy), with an average of 144,400 kilowatt-hours per capita.

If this value is announced, it can scare people to death.

As for whether such crazy plans to launch a nuclear power plant will cause climate change on Blue Star, the Academy of Sciences, the Academy of Engineering, and the Department of Suiren Research conducted a climate simulation.

The emergence of controllable nuclear fusion nuclear power plants will not have a big impact on Blue Star's climate for the time being, and may even alleviate global climate cooling to a certain extent.

Many people are worried that nuclear fusion power plants will cause global warming, but this will not be manifested in a short time.

After all, since humans detonated the first nuclear bomb, thousands of nuclear explosion experiments have been carried out around the world, especially Lao Maozi's Big Ivan, which has an equivalent of more than 50 million tons, which is not as much as the energy released by a small earthquake.

In fact, the heat in the ecological environment of blue stars mainly comes from the stellar radiation energy of the sun and the geothermal energy of nuclear decay in the mantle and core.

The heat generated by humans detonating nuclear bombs or nuclear power plants is not large enough to compare with both.

At least in Huang Weichang's understanding, with the general trend of global cooling, unless human civilization works together to set fire to the mountains and run thermal power stations at full capacity, it will be difficult to reverse the climate change.

However, everyone is now clearing the door. In North America and Western America, where the economy is sluggish, the factory operating rate is less than 46%.

As the world’s factory, Greater China’s carbon emissions are becoming less and less due to technological innovation.

There was originally a quasi-world factory, Tianzhu, but it also became a mess due to internal and external difficulties.

As for other regions, it is not that Huang Weichang looks down on them, but that they are indeed not qualified to participate in such world-class issues.

Of course, if the oil tyrants in West Asia can make the determination to continuously pump out the oil and natural gas in their own oil fields and burn them, it may be possible to slow down the rate of global cooling.

But the only strategic resource in West Asia is oil and natural gas. If they are allowed to burn their own oil and gas resources to warm the world, they might as well take a few more breaths of cold air.
