切尔诺贝利

发电机转子开始减速
Generator rotor beginning rundown.
凌晨1点23分04秒
1:23:04.
他们做的每个决定
With every decision,
都让这个反应堆像弹弓一样被拉开
they have pulled this reactor back like a slingshot,
拉得比任何人都开
further than anyone has ever pulled,
现在测试开始了
now the test begins.
水泵停了 他们放手了
The pumps are shut down, and they've let go.
水泵停止向反应堆输水
The pumps stop moving water through the reactor.
铀燃料现在不受新冷却剂控制
Uranium fuel is now unchecked by fresh coolant,
不受控制棒控制
unchecked by control rods.
平衡立刻偏向了另一边
The balance immediately swings in the opposite direction.
不到一秒内
In less than a second,
反应性开始增加
reactivity increases.
在堆芯内部
Inside the core,
剩余的水迅速转为蒸汽
the remaining water is quickly converting to steam.
出现了一个空泡
A void is being created.
却没有水输入填补它
There is no fresh water to replace it.
蒸汽增加反应性
Steam increases reactivity,
增加热量 又产生蒸汽
increases heat, increases steam,
增加反应性
increases reactivity.
剩余氙气持续衰变
The remaining xenon decays away.
功率上升
The power is rising.
没什么可以阻止了
There's nothing left to stop it.
凌晨1点23分35秒
1:23:35.
功率激增 萨沙
We have a power surge! Sasha!
你做了什么
What did you do?!
凌晨1点23分40秒
1:23:40.
全世界的所有核反应堆的所有控制室里
In every control room of every nuclear reactor in the world,
有一个按钮 它只有一个用途
there is a button with one single purpose
"紧急停堆" 或立即停止反应堆运行
to "scram," or instantly shut down, the reaction.
在苏联核反应堆设备中 这个按钮叫AZ-5
In Soviet reactors, that button is called AZ-5.
一旦按下AZ-5 所有控制棒会立即插入
You press AZ-5, all of the control rods insert at once,
核反应也会立刻停止
and the reaction is stopped dead.
但是...
But...
你在等什么 列加索夫 说谎啊
What are you waiting for, Legasov? Tell your lies.
迪亚特洛夫同志 这是你的最后一次警告
Comrade Dyatlov, you will not be warned again.
-不然呢 -消停点吧 迪亚特洛夫
- Or what? - For god's sake, Dyatlov.
列加索夫已经暴露了
Legasov's already given it away.
他之前就说了
He said before,
-迪亚特洛夫同志 -没办法阻止爆♥炸♥的发生
- Comrade Dyatlov. - there was no way to avoid what was coming.
-他知道内♥幕♥ 她也知道 -迪亚特洛夫同志
- He knows something. She knows something. - Comrade Dyatlov.
我知道你是什么货色 瓦列利·阿列克谢维奇
I know what you are, Valery Alexeyevich.
-你是个骗子 -今天我们听得够多了
- You're a liar. - We've heard enough for today.
被告将还押候审
The defendants will be remanded in custody.
-本庭... -我还没说完
- Court will-- - I... I haven't finished.
我还有更多证据
I still have more evidence to give.
不用了 你的证词已经完整了
It's not necessary. Your testimony is concluded.
-法官阁下 -本庭休庭
- Your Honor. - Court is now adjourned.
-明天继续... -让他说完
- We will resume tomorrow with-- - Let him finish.
谢比纳同志
Comrade Shcherbina...
让他说完
Let him finish.
迪亚特洛夫破坏了所有规则
Dyatlov broke every rule we have.
他将反应堆状态推向了毁灭边缘
He pushed a reactor to the brink of destruction.
他这么做是因为他确信核反应堆有保险装置
He did these things believing there was a failsafe.
AZ-5 一个能停止一切反应的按钮
AZ-5, a simple button to shut it all down.
但在他所制♥造♥的情形下 已不存在保险装置
But in the circumstances he created, there wasn't.
紧急停机系统有个致命的缺陷
The shutdown system had a fatal flaw.
在凌晨1点23分40秒
At 1:23:40,
阿基莫夫按下了AZ-5
Akimov engages AZ-5.
被完全拔出的控制棒
The fully-withdrawn control rods
开始重新插入反应堆
begin moving back into the reactor.
这些控制棒是硼制的 硼能减弱核反应
These rods are made of boron, which reduces reactivity,
但控制棒的尖端不是
but not their tips.
尖端是石墨制 而石墨会加快核反应速率
The tips are made of graphite, which accelerates reactivity.
为什么
Why?
为什么
Why?
和我们的核反应堆
For the same reason our reactors
没有反应堆安全壳的原因一样
do not have containment buildings around them,
西方国家都有
like those in the West.
和我们的堆芯
For the same reason we don't use
不使用适当浓缩的燃料原因一样
properly enriched fuel in our cores.
和我们是唯一一个核反应堆
For the same reason we are the only nation
使用流水冷却 用石墨做缓和剂
that builds water-cooled, graphite-moderated reactors
带有正空泡系数的国家一样
with a positive void coefficient.
更便宜
It's cheaper.
首先与堆芯接触的控制棒部份
The first part of the rods that enter the core
是尖端的石墨
are the graphite tips.
当发生接触后 堆芯在持续加剧的
And when they do, the reaction in the core,
核反应 瞬间激增
which had been rising, skyrockets.
液态水的所有分子
Every last molecule of liquid water
瞬间汽化为蒸汽
instantly converts to steam,
使得大批燃料管道膨胀并破裂
which expands and ruptures a series of fuel rod channels.
这些管道里的控制棒已无法再插入
The control rods in those channels can move no further.
石墨尖端被固定
The graphite tips are fixed in position,
导致无止境地加速核反应
endlessly accelerating the reaction.
切尔诺贝利4号♥反应堆此时就是个核弹
Chernobyl Reactor 4 is now a nuclear bomb.
凌晨1点23分42秒
1:23:42.
佩罗沃钦科往下看
Perevozchenko looks down
那巨大的反应堆钢盖
on the enormous steel lid of the reactor...
看到了难以置信的景象
...and sees the impossible.
每个重达350公斤的
The control rod and fuel channel caps,
控制棒和燃料管道盖子
which each weigh 350 kilograms,
正上下跳动着
are jumping up and down.
他跑去警告控制室
He runs to warn the control room.
但他已经无法阻止即将发生的事情
But there's nothing he can do to stop what is coming.
1点23分44秒
1:23:44.
蒸汽鼓破了更多燃料管道
The steam blows more fuel channels apart.
我们不知道功率究竟达到了多高
We do not know how high the power went.
我们只知道最后的读数
We only know the final reading.
4号♥反应堆
Reactor 4,
原额定功率为3200兆瓦
designed to operate at 3200 megawatts,
最后超过了33000兆瓦
went beyond 33,000.
堆芯再无法承受如此巨大的压力
The pressure inside the core can no longer be held back.
最终 导致了
At long last, we have arrived.
1点23分45秒的大爆♥炸♥
1:23:45, explosion.
在反应堆盖子被掀开的瞬间
In the instant the lid is thrown off the reactor,
氧气冲了进来
oxygen rushes in.
与氢和过热的石墨混合
It combines with hydrogen and super-heated graphite.
灾难链在此时也构建完成了
The chain of disaster is now complete.
迪亚特洛夫同志
Comrade Dyatlov!
迪亚特洛夫同志
Comrade Dyatlov!
那一晚在控制室里
No one in the room that night knew
谁也不知道紧急停机按钮相当于引爆器
the shutdown button could act as a detonator.
他们并不知道
They didn't know it,
因为这一点被刻意隐瞒了
because it was kept from them.
列加索夫同志 这和你
Comrade Legasov, you're contradicting
在维也纳的证词自相矛盾
your own testimony in Vienna.
我在维也纳撒谎了
My testimony in Vienna was a lie.
我向全世界撒了谎
I lied to the world.
我不是唯一一个保守这个秘密的人
I'm not the only one who kept this secret.
还有许多人
There are many.
我们都只是服从命令
We were following orders,
服从克格勃 服从中♥央♥委员会
from the KGB, from the Central Committee.
而现在 苏联境内还有16个反应堆
And right now, there are 16 reactors in the Soviet Union
有着同样的致命缺陷
with the same fatal flaw.
其中三个就在距离切尔诺贝利
Three of them are still running
不到20公里的地方运行着
less than 20 kilometers away at Chernobyl.
列加索夫教授 如果您的意思是
Professor Legasov, if you mean to suggest the Soviet State
苏联应对所发生的一切负责
is somehow responsible for what happened,
那我必须警告您 您的立场很危险
then I must warn you, you are treading on dangerous ground.
