Two days later, a military helicopter flew over the barren western desert, and Yang Jie on top of the helicopter also looked at the rolling desert below through the porthole.

Sitting next to Yang Jie was a sturdy middle-aged man, wearing a military uniform, and the two gold stars and golden branches and leaves on the epaulettes shone brightly.

"General Gao, this Beishan No. 1 construction site is deep in the desert, and the construction conditions are relatively difficult, so it is very difficult for your engineering troops to construct, right?"

Yang Jie turned his head and said to this General Gao Zhiwei.

"Our missile engineering unit has always been working in places where the conditions are difficult, and we have to find ways to overcome difficulties. ”

General Gao Zhiwei said.

He was the commander of the engineering unit of the Second Artillery Corps, and he undertook all major national defense engineering projects; in the past, he was the construction of underground depots for strategic nuclear missiles for the missile unit and the construction of some underground command projects of the Central Military Commission and the theater of operations.

Although the tasks carried out by this unit led by General Gao Zhiwei are mostly military secrets, and although it has the highest rank in the army as an engineering unit, this unit is also the target of the intelligence organs of many countries, including Yingjiang, and the officers and men, including General Gao Zhiwei, must keep a low profile incognito.

This is also the first time he has dealt with Yang Jie, and he still keeps a certain distance from the handsome young rich man in front of him.

Yang Jie smiled and didn't say anything.

Dozens of minutes later, the helicopter also came to the middle of a valley with rolling mountains, and at this time, you could see a piece of engineering board houses built below, and you could also see continuous construction vehicles shuttling back and forth.

Moments later, the helicopter landed in an open field, kicking up a cloud of dust.

Yang Jie and Gao Zhiwei got down from the helicopter, and the people waiting there also hurried to meet them.

"Chief Gao, Yang Dong, we have prepared Chinese rice, why don't you eat Chinese food first?"

Gao Zhiwei glanced at Yang Jie at this time and said, "Dong Yang, what is your opinion?"

"Then let's eat first, after eating, I want to go to the cave of the Beishan No. 1 Project to have a look. ”

Yang Jie opened his mouth and said.

The Beishan No. 1 project is the first large-scale permanent nuclear waste resettlement project in China, which was originally started after 2000, and the Address Exploration Bureau also selected this place, and drilled more than a dozen wells to carry out a 50-meter underground pit rock stability test, preparing to build a medium-term nuclear waste resettlement project, and because the funds are not available, the progress is very slow.

After Yang Jie agreed to personally pay out of his own pocket to build a large-scale permanent nuclear waste resettlement project for the country, the central authorities also attached importance to this matter, and handed over the project to this missile engineering unit for construction, and the speed was suddenly accelerated.

In the past two years or so, the missile engineering unit has drilled hundreds of 500-meter-deep wells near Beishan, obtained a large amount of raw data on the performance of underground rocks in the Beishan area, and also figured out the underground geological conditions on the Beishan side, believing that the geological conditions of Beishan are very superior, and that it is located in a stable area of crustal movement, and that the selected reservoir site has a complete granite mass, and granite is the best rock layer for dealing with radiation.

The underground project involves building a super-large cavern at a depth of 500 meters, then digging horizontal tunnels around the cavern, stacking sealed containers containing nuclear waste in each tunnel, and finally sealing the tunnels.

In this way, spent fuel can be permanently sequestered until it is largely radioactive after 100 years.

In the past, this missile engineering unit had been engaged in extremely large underground military engineering projects, and the construction of underground silos and underground headquarters were all projects to evacuate the interior of the mountain, and these projects needed to withstand natural earthquakes or strong vibrations during a nuclear attack, and the complexity and difficulty of the projects were very great.

Now tens of thousands of officers and soldiers of the engineering unit have begun to be stationed here to start the construction of this Beishan No. 1 project, and Yang Jie is also relieved about this.

After lunch, Yang Jie and others also followed the cement truck to the entrance of this huge tunnel.

The tunnel has been poured with reinforced concrete, so you can't see the surrounding rock cuts, and it is also very spacious, and the conveyor belt extending from the tunnel conveys a large amount of debris out.

After driving thousands of meters, the construction vehicle finally arrived at the construction site, and at this time, a full-section rock boring machine could be seen working in the deep cave in front of it.

This set of full-section rock boring machines specially built by Huaxing Construction Machinery Group for the Beishan No. 1 project is now continuously and completely excavated at a maximum speed of more than 120 meters per day, which is twice the excavation speed of artificial rockburst.

This is also the first time that the engineering unit has used this kind of full-section super-large full-section rock boring machine, and this time Huaxing Construction Machine also sent engineering and technical personnel to carry out the maintenance of this set of equipment.

Gao Zhiwei had an opinion on the China Nuclear Energy and Environmental Protection Research Institute's insistence on using the TBM equipment of Huaxing Construction Machinery Group Company at the beginning, believing that such equipment technology is not easy to serve, and it is necessary to drill some working wells for this set of equipment.

However, after using it for nearly two months, the outstanding performance of this set of equipment of Huaxing Construction Machinery Group Company also convinced the officers and soldiers of these engineering units, and with this set of equipment, the speed of tunnel excavation is very fast.

Yang Jie and others also came to the control room of the shield machine to understand the situation, and when he learned that this set of equipment has been working smoothly so far, he was also very satisfied.

The tunnel of the Beishan No. 1 project will be excavated in a spiral shape with a radius of 1,000 meters into the underground rock layer, and finally excavated to a depth of 500 meters, with a length of more than 20 kilometers, and the whole project will take at least five or six years to start use.

In order to ensure that this underground cavern can be used for hundreds of years, Yang Jie would rather spend more money to adopt this engineering method, after all, the use of vertical shafts will cause these lifting equipment to fail if it takes too long, and the use of this spiral tunnel in and out of the underground can always operate.

Over the past three decades, several options have been proposed for how to dispose of nuclear waste, including transporting it to the sun, burying it in the Arctic and storing it on the seabed, but nuclear waste experts generally agree that the best way to dispose of nuclear waste in geological formations is to do so.

The Beishan No. 1 site has no groundwater and oil, the rock formation is very stable and solid, and core sampling also shows that the rocks deep underground were formed billions of years ago, ensuring that the stored nuclear waste will not leak and pollute the groundwater.
