At Tsinghua University
There is a mysterious code name that is widely circulated
"Number 200"
"No. 200" is actually at the foot of Yanshan Mountain
The code name of the Institute of Nuclear energy and New Energy Technology of Tsinghua University
And at the Science Museum at Tsinghua University
There is a safety rod drive mechanism hidden
It was donated by the Tsinghua Institute for Nuclear Research
It was installed in China's first independently designed and built
On a nuclear reactor
The safety bar drive mechanism is a sports device
It's like a "conductor."
Waving the "baton"
Let the safety rods made of special materials absorb neutrons
It plays the function of emergency shutdown and nuclear leakage prevention

The 1950s
The international security situation is becoming increasingly grim
The Party Central Committee makes strategic decisions
We must develop the atomic energy industry in New China
In 1958
Faculty and students of the Department of Engineering Physics of Tsinghua University
Decided to start building
China's first nuclear reactor designed and commissioned by itself
Infrastructure project number is "No. 200"
The average age of the team members of the "200" team is only twenty-three and a half years old
This is the origin of the "23-year-old and a half legend"

When construction of this nuclear test reactor begins
Lack of people, lack of money, lack of technology
I don't know where to start
Let's start with a model of horse manure cardboard
They started with this model of horse dung paper
With dozens of hand-cranked computers
Overcome difficulties step by step
It took 6 years
It was finally built in 1964
Shielded nuclear reactors
A number of indicators exceed the level of the original foreign reference design
Just won the country's highest science and technology award

Safe operation of the reactor
Safety bars are one of the most critical devices
It can be said to be the "brake"

Shielded test reactor built from 1964
Then to the cryogenic nuclear heating reactor in 1989
High temperature gas-cooled experimental reactor in 2000
The safety performance of reactors continues to rise
From passive safety to active safety

It is one of the low-temperature nuclear heating reactors
and host of the high temperature air-cooled experimental reactor

Today
There are more than 50 nuclear power units in operation in mainland China
They are all extremely safe
A small safety rod on the Tsinghua shielding test reactor
It is a starting point for the safety of China's nuclear industry
