Congratulations, comrades.
You're the last of 3,828 men.

(SOMBER MUSIC PLAYS)

ULANA KHOMYUK: I found
this in the state archive.

I need your help.

Can you confirm that
the reactor exploded

after they attempted to shut it down?

What, you think the right question

will get you the truth?

VALERY LEGASOV: They're
going to put Dyatlov on trial.

We're going to be asked
to give expert testimony.

KHOMYUK: I've analyzed the data.

They shut the reactor
down, and then it exploded.

You've seen this before.

I had no idea it could
cause an explosion.

- BORIS SHCHERBINA: So, it is their fault?
- LEGASOV: Yes.

KHOMYUK: But not only their fault.

SHCHERBINA: We can make
a deal with the KGB.

You'll leave this
information out in Vienna.

They quietly let us fix
the remaining reactors.

KHOMYUK: You have a chance
to talk to the world.

Someone has to start telling the truth.

(MUSIC CONCLUDES)

(BIRDS SINGING)

I hear they might promote Bryukhanov.

This little problem we
have with the safety test...

if it's completed successfully,

yes, I think promotion's very likely.

Who knows, maybe Moscow.

Naturally, they'll put me
in charge once he's gone,

and then I'll need
someone to take my old job.

I could pick Sitnikov.

I would like to be considered.

I'll keep that in mind.

Viktor Petrovich,

preparations for the
test have gone smoothly.

Comrade Dyatlov's been
working per my instructions,

and Reactor 4 output's been
reduced to 1600 megawatts.

With your approval, we're ready
to continue lowering power to...

We have to wait.

Is, uh...?

Are you going to ask me if
there's a problem, Nikolai?

You can't read a fucking face?

Three years, I've tried
to finish this test.

Three years.

I've just had a call from
the grid controller in Kiev.

He says we can't lower
power any further,

not for another ten hours.

The grid controller?
Where does he get off...

It's not the grid
controller's decision, Dyatlov.

It's the end of the month.

All the productivity quotas.

Everyone's working overtime,
the factories need power.

Someone's pushing down from above.

Although, we'll never know who.

So, do we have to scrap it or what?

No, I don't think so.

If we need to wait ten hours,

- we wait
- Running at half power,

we're not going to
have stability issues?

- No, I-I should think...
- I'm not asking you.

DYATLOV: It's safe.

We'll maintain at 1600.

I'll go home, get some
sleep, come back tonight.

We'll proceed then.

I'll personally supervise the test.

And it will be completed.

Well, I'm not waiting around then.

Call me when it's done.

(PEDESTRIANS CHATTERING)

(VOICES MURMURING)

How do you feel?

You went to the doctor yesterday.

How is your health?

You don't know?

From Vienna.

Do you read German?

It says, "At last a Soviet
scientist who tells the truth."

Obviously, I resent the insinuation,

but I think it's fair to say,

you made an excellent
impression at the conference.

Turns out, you're quite good at this.

At what? Lying?

Statecraft, Legasov. Statecraft.

The West is now satisfied

that Chernobyl was solely
the result of operator error,

which it essentially was.

We have you to thank for that,

and we intend to.

"Hero of the Soviet Union."

Our highest honor.

They haven't even given it to me.

"Promotion to Director of
the Kurchatov Institute."

I'm humbled.

I don't think there's anything
humble about you, Valery Alexeyevich.

These rewards are not yours yet.

First, your testimony at the trial.

Comrade Charkov, I understand
my duty to the State.

But you gave us assurances.

The reactors would be made safe.

It's been months, no
changes have been made.

- No changes even discussed.
- First, the trial.

Once it's over, we
will have our villains,

we will have our hero,
we will have our truth.

After that, we can
deal with the reactors.

(CLOCK TICKING)

(LOUD KNOCKING)

(SIGHS)

Did you take a train?

Yes, I took a train.

Now let's talk about Vienna.

I'm not here to scold you.

I know how the world works
despite what Shcherbina says.

So... why are you here?

Because I'm brutally stubborn.

Which you were hoping for.

Charkov is saying they're going to
fix the reactors after the trial.

Do you believe him?

(SCOFFS)

The State will never
willingly fix the reactors,

because acknowledging the problem
means admitting that they lied.

They will have to be forced.

At the trial, you're
going to tell the truth.

You're going to convince the jury.

(SCOFFING): It's a show trial.

The jury's already been
handed their verdict.

I'm not talking about them.

The Central Committee have invited

members of the scientific
community to observe the trial.

Our colleagues, from Kurchatov,

from Sredmash, from Minenergo,

they will be sitting in the crowd
listening to every word you say.

A jury that only we know is there.

And when your testimony arrives
at the moment of the explosion?

That is when our jury will
finally hear the truth.

- And do what with it?
- Insist on reform.

(SCOFFS)

Not just to the RBMK,
but the entire industry.

No, no, no, no, no.

- They can't function without us.
- No, no, no.

Do you know what happened to Volkov

the man whose report you found?

They just removed him from
his position at the Institute.

Sacked for the crime of knowing.

And you think that these scientists,

handpicked to witness a show trial,

will somehow be stirred
into action by me?

Because of some heroic stance
I take in defiance of the State?

- Yes.
- Why?

Because you're Valery Legasov,
and you mean something.

(SCOFFS)

I'd like to think that if I
spoke out, it would be enough.

But I know how the world works.

They will shoot me, Khomyuk.

You told me to find out what happened.

I spoke to dozens of people.

Every word they said, I wrote down.

All in these books.

These are the ones who are still alive.

These are the ones who are dead.

They died rescuing each other.

Putting out fires,
tending to the wounded.

They didn't hesitate,
they didn't waiver.

They simply did what had to be done.

So have I.

So have I.

I went willingly to an open reactor.

So I've already given my life.

Isn't that enough?

No, I'm sorry, but it is not.

The Central Committee of the
Communist Party of the Soviet Union

and the Presidium of the
Supreme Soviet of the U.S.S.R.

has determined that
justice be carried out

on behalf of the People

in accordance with the
general goal of our Party

as determined by its 20th,
21st, and 22nd Congresses,

which is a Leninist goal.

It was, is, and will be

the only immutable goal
in the Soviet state.

The path of Leninist principles

shall be consistently
and undeviatingly followed

as it expresses the vital
interests of the Soviet People,

its hopes and aspirations

as we guide the life of
the Party and the State.

This session of court is now open,

Comrade Judge Milan Kadnikov presiding.

Indictments:

Viktor Bryukhanov,

Anatoly Dyatlov,

Nikolai Fomin...

are accused of violating
Article 220 Section 2

of the Criminal Code
of the Soviet Union,

resulting in a nuclear
disaster on April 26, 1986.

The State calls
witnesses Comrade Khomyuk

of the Byelorussian Nuclear Institute,

Comrade Legasov of the Kurchatov
Institute of Atomic Energy,

and Comrade Boris
Evdokimovich Shcherbina,

Deputy Chairman of the
Council of Ministers

and head of the Bureau
for Fuel and Energy.

It began with, of all
things, a safety test.

Why was there need for
a safety test at all?

Reactor Number 4 was not new
when the accident occurred.

In fact, it went into operation
on December 20th, 1983.

Eleven days later, on
the last day of the year,

Plant Director Viktor Bryukhanov
signed this document...

certifying the completion of
the construction of the reactor.

As a result of finishing the
work before the end of the year,

Comrade Bryukhanov was awarded
Hero of Socialist Labor.

Comrade Fomin was awarded
for Valorous Labor.

Comrade Dyatlov was given
an Order of the Red Banner.

But their work was not finished.

And this document was a lie.

In order to sign this certificate,

all safety tests had to have
been successfully completed,

and yet, one remained.

A nuclear reactor generates
heat in the core here.

A series of pumps, here and here,

send a constant flow of
cooling water through the core.

The core's heat turns
the water to steam,

and the steam spins the turbine here,

and the result is electricity.

But what if a power plant has no power?

What if the power feeding
the plant itself is disrupted?

A blackout, equipment failure,

or an attack by a foreign enemy?

If there's no power,

the pumps cannot move
water through the core.

And without water, the core overheats,

the fuel melts down.

In short, a nuclear disaster.

The solution?

Three diesel fuel
backup generators here.

So, problem solved?

No.

Bryukhanov knew that the
problem was not solved at all.

The backup generators took
approximately one minute

to reach the speed required

to power the pumps
and prevent a meltdown,

and by that time, it would be too late.

So we arrive at the safety test.

The theory was this: If
the facility lost power,

the turbine, which had been spinning,

would take some time
to slow down and stop.

What if you could take the electricity

it was still generating and
transfer it to the pumps?

What if the dying turbine

could keep the pumps working long enough

to bridge the 60-second gap
until the generators came on?

(COUGHING)

Any questions?

KADNIKOV: No. Continue, please.

To test this theory,

the reactor is placed in
a reduced power mode...

700 megawatts...

to simulate a blackout condition.

Then the turbines are turned off,

and as they slowly spin down,

their electrical output is measured

to see if it's enough
to power the pumps.

The science is strong,

but a test is only as good
as the men carrying it out.

Now, the first time
they tried, they failed.

The second time they tried, they failed.

The third time they tried, they failed.

The fourth time they tried

was April 26th, 1986.

STEPASHIN: Comrade Khomyuk.

(BREATHES DEEPLY)

To understand what happened that night,

we have to go back ten hours earlier...

April 25th, the day the
test was meant to take place.

By two in the afternoon,

the reactor has been lowered by half

from its normal output
level of 3200 megawatts

to 1600 megawatts and is stable

and ready to be reduced to its
final output level for the test:

700 megawatts.

But before they can proceed,
there is a phone call.

Power grid officials in Kiev
say that they cannot afford

a further reduction in the
electricity until after midnight.

They are asking for a ten-hour delay.

This is the first critical moment,

the first link in the chain of disaster.

Competent management would have
insisted on canceling the test.

These three men allowed it to proceed.

Why was this delay so dangerous?

It created two problems:

One of them is scientific in nature...

and the other is very human.

This is the one we will consider first.

At midnight, there is a shift change.

- (MEN CHATTERING)
- Hey.

- Khodemchuk...
- Forget it. Find another fool.

Toptunov, want to buy a motorcycle?

BRAZHNIK: Toptunov?
He's just a little boy.

He's got more hair on his
face than on his balls.

Hair? Is that what's on his lip?

(MEN CHUCKLING)

Leonid Fedorovych.

Akimov says to come to the
control room as soon as you can.

- Is he already here?
- He came in early.

Something about a test.

- You see? Desperate.
- (INDISTINCT CHATTER)

TOPTUNOV: Sasha?

Ah. You know the test
they were supposed to run?

The turbine rundown,
they tried it last year.

They couldn't do it on the day
shift, so they've given it to us.

To us?

- We don't know what...
- AKIMOV: Shh.

- (WHISPERING): We don't know what it is.
- It's fine.

We take it down to 700, hold it there,

the rest is Stolyarchuk
and Kirschenbaum, but...

Dyatlov is gonna be supervising.

I have to do something
I've never done before

with Dyatlov looking over my shoulder?

Yeah, well, don't worry,
we'll do it together.

I'm looking at the instructions now.

Are we supposed to do those or not?

Yes, this is Akimov in 4.

I have the manual for the rundown test.

You did it last year.

Yes, in the program there's
instructions of what to do,

and then, well, there's a
lot of things crossed out.

What should I...?

Well, what should I...?

Are you sure?

Right. Thank you.

He says to follow the
crossed-out instructions.

So then why are they crossed out?

(DOOR OPENS)

We've been cleared to run the test.

1600. Good.

Now, is it too much to ask that
you all know what you're doing?

- Well...
- Yes. Absolutely.

- Stolyarchuk?
- Yes.

- Kirschenbaum?
- Uh, I haven't reviewed.

We only just found out really...

There, review it.

Or you can just do what I tell you.

I think even you, stupid
as you are, can manage that.

Well, let's go.

I'm supposed to switch the turbine
off while the reactor's still running?

- This is not good...
- Shut the fuck up and do your job!

Toptunov, reduce power to 700.

(WHISPERING): I've never done
this with the power so low before.

(WHISPERS): It's okay. I'm with you.

Reducing power to 700.

KHOMYUK: I want you to
think of Yuri Gagarin.

I want you to imagine that
he has been told nothing

of his mission into space until the
moment that he is on the launch pad.

I want you to imagine that all he has

is a list of instructions
that he has never seen before,

some of which have been crossed out.

This is exactly what was happening

in the control room of Reactor 4.

The night shift had not been
trained to perform the experiment.

They hadn't even been
warned it was happening.

Leonid Toptunov,

the operator responsible for
controlling and stabilizing

the reactor that night
was... all of 25 years old.

And his total experience on the job?

Four months.

This is the human problem
created by the delay.

But inside the reactor core,

in the space between
the atoms themselves,

something far more dangerous is forming.

A poison.

The time is 28 past midnight.

Comrade Legasov.

(BREATHES DEEPLY)

(PUSHCART ROLLING)

I'm pleased to see some
of my colleagues here

from the Kurchatov
Institute and Minenergo.

But you don't need to
be a nuclear scientist

to understand what
happened at Chernobyl.

You only need to know this:

there are essentially
two things that happen

inside a nuclear reactor.

The reactivity which generates power

either goes up, or it goes down.

That's it.

All the operators do
is maintain balance.

Uranium fuel.

As uranium atoms split
apart and collide,

reactivity goes up.

But if you don't balance the reactivity,

it never stops rising. So...

Boron control rods.

They reduce reactivity
like brakes on a car.

But there's a third
factor to consider: water.

Cool water takes heat out of the system.

As it does, it turns to steam,
or what we call a "void."

In an RBMK reactor of the
type used at Chernobyl,

there's something called a
"positive void coefficient."

What does that mean?

It means that the more steam
present within the system,

the higher the reactivity,

which means more heat,
which means more steam,

which means...

It would appear we have a
vicious cycle on our hands.

And we would, were it not for this...

(CLATTERS)

And we would, were it not for this:

the negative temperature coefficient.

When nuclear fuel gets hotter,
it gets less reactive, so...

fuel increases reactivity.

Control rods and water reduce it.

Steam increases it,

and the rise in temperature reduces it.

This is the invisible dance

that powers entire cities
without smoke or flame.

And it is beautiful

when things are normal.

As uranium splits
apart to release energy,

it breaks down into
a new element, xenon.

Xenon reduces reactivity.

This is the poison
Comrade Khomyuk mentioned.

When the core is running at full power,

it burns the xenon away
before it can cause a problem.

But because of the delay,

Chernobyl Reactor 4 has
been held at half power

for ten hours.

The xenon did not burn away.

It built up, poisoning the core.

We're starting to lose balance.

- (COUGHING)
- At 28 minutes past midnight,

the reactor is now primed to slow down.

And yet, in less than
an hour, it will explode.

If you can't understand how
a stalled nuclear reactor

could lead to an explosion,
I don't blame you.

After all, you don't
work in the control room

of a nuclear power plant.

But as it turned out, the men who did

didn't understand it either.

(COMPUTERS HUMMING)

Easy now.

Take it down.

Good. Like that.

DYATLOV: You should
have finished by now.

We're following protocol
for reduction rate.

You're procrastinating.

There are ten other men in this
plant who would've done it already.

(WHISPERS): Keep working.
You're doing fine.

Kirschenbaum, come get me
when these old women are ready.

Yes, Comrade Dyatlov.

Okay, very slow now.

Let's ease it down to 700.

- Whoa, whoa, whoa. Slow.
- I-I didn't move any rods there.

- What is this?
- I'm not even touching it.

We did everything right. I think
that maybe the core is poisoned.

Well, if you thought
the core was poisoned,

then you didn't do everything right,

because you're choking my reactor!

Get it back up!

Uh, I think if we turn off LAC,

it may be possible to get more control.

- Do it. Go.
- Switch off local automatic control.

Go to global. Leonid.

LAC disabled. Global control activated.

What did you do?

- I-I did what you said. I switched...
- DYATLOV: Look at it!

- AKIMOV: I don't understand.
- DYATLOV: Fucking amateurs.

You stalled the reactor.

How the fuck did you get this job?

Comrade Dyatlov...

You're gonna tell me you
did everything right again,

you incompetent asshole?

I apologize for this
unsatisfactory result.

- What are you doing?
- We have to shut all the way down.

- No.
- We could be in a xenon pit.

We have to shut down
and wait for 24 hours.

No. We're doing the test
tonight. Raise power to 700.

We can't raise the power from here.

- The rules...
- Don't talk to me about rules.

- If we fall from 80%...
- No, no. We fell from 50%.

- AKIMOV: Fifty percent is worse!
- The rules don't say 50!

- There is no rule!
- Comrade Dyatlov,

I apologize, but what
you're saying makes no sense.

- Raise the power.
- No.

I won't do it. It isn't safe.

Safety first. Always.

I've been saying that for 25 years.

That's how long I've
done this job, 25 years.

Is that longer than you, Akimov?

Yes.

- Is it much longer?
- Yes.

And you with your mother's
tit barely out of your mouth?

So if I say it's safe, it's safe.

And if the two of you disagree,

then you don't have to
work here and you won't.

But not just here.
You won't work at Kursk

or Ignalina or Leningrad
or Novo-Voronezh.

You won't work anywhere
ever again. I'll see to it.

I think you know I will see to it.

Raise the power.

I would like you to record your command.

Raise the power.

(BREATHING SHAKILY)

Together, then.

DYATLOV: I wasn't even there.

- (VOICES MURMURING)
- LEGASOV: What?

I wasn't in the room when
they raised the power.

If you weren't there,
then where were you?

Comrade Legasov, you are a
witness, not a prosecutor.

I will ask the questions here.

If you weren't in the
room, then where were you?

The toilet.

(VOICES MURMURING)

STEPASHIN: The toilet?

Comrade Khomyuk interviewed everyone

who was in the control room that night.

They all told the same story.

"I knew what Dyatlov ordered was wrong,

but if I didn't do what
he said, I would be fired."

Leonid Toptunov.

One day before he died.

No, Comrade Dyatlov,
you were in the room.

You ordered them to raise the power.

- This is a fact.
- (SHCHERBINA COUGHING)

(COUGHING CONTINUES)

Court is now in recess.

Thirty minutes.

(COUGHING)

Do you know anything
about this town, Chernobyl?

Not really, no.

It was mostly Jews and Poles.

The Jews were killed in pogroms,

and Stalin forced the Poles out.

And then the Nazis came
and killed whoever was left.

But after the war...

people came to live here anyway.

They knew the ground under
their feet was soaked in blood,

but they didn't care.

Dead Jews, dead Poles.

But not them.

No one ever thinks it's
going to happen to them.

And here we are.

How much time?

Maybe a year.

They call it a... (COUGHS)

They call it a "long illness."

It doesn't seem very long to me.

I know you told me, and I believed you.

But time passed, and I thought,

it wouldn't happen to me.

I wasted it.

I wasted it all for nothing.

For nothing?

Do you remember that morning
when I first called you,

how unconcerned I was?

I don't believe much that
comes out of the Kremlin,

but when they told me
they were putting me

in charge of the cleanup

and they said it wasn't
serious, I believed them.

You know why?

Because they put you in charge.

Yeah.

I'm an inconsequential man, Valera.

That's all I've ever been.

I hoped that one day I
would matter, but I didn't.

I just stood next to people who did.

There are other scientists like me.

Any one of them could
have done what I did.

But you...

Everything we asked for,
everything we needed.

Men, material, lunar rovers.

Who else could have done these things?

They heard me, but they listened to you.

Of all the ministers
and all the deputies...

entire congregation of obedient fools...

they mistakenly sent the one good man.

For god's sake, Boris,

you were the one who mattered most.

Ah, it's beautiful.

(CROWD MURMURING)

(SIGHS)

STEPASHIN: Comrade Legasov.

LEGASOV: The time is 38 past midnight.

The reactor is nearly shut down.

The operators of Reactor
4 are locked on a path

that leads directly to disaster.

There's no way to turn back.

They do not yet know
it, but the die is cast.

At 30 megawatts, xenon
is still being created,

but none of it is burning away.

The reactor is drowning in poison.

To make matters worse, the
reactor isn't hot enough

to produce sufficient steam.

The only way to safely
raise power from this state

is to do it very, very slowly

over the course of 24 hours.

But Dyatlov wants it done now.

Akimov and Toptunov have
only one course of action.

They begin pulling control rods out.

Dozens at a time.

Halfway out, three-quarters
of the way out,

still, the power does not budge.

So they begin pulling
them all the way out.

There were 211 control
rods in Reactor 4.

Akimov and Toptunov
completely withdrew 205.

Remember... control rods
are the brakes on this car.

Of 211 rods, only six
now remain in the reactor.

As for the fuel, it's gone cold,

so the negative temperature coefficient

is no longer weighing
down the reactivity.

But even still, the xenon
poisoning is so strong,

the best they can do is raise
the power to 200 megawatts.

The control rods are out.

The emergency system
has been disconnected.

The only thing keeping
the reactor in check

is water and xenon.

It's one in the morning.
The test is minutes away.

(BUTTONS CLICKING)

(BUTTONS CLICKING)

I'm sorry, this is all we can get.

It's 200 megawatts. We've
pulled almost everything out.

If that's all we have,
that's all we have.

- But the test requires 700.
- Stolyarchuk, let's get ready.

- Switch on pump 4.
- AKIMOV: No, wait a second.

- DYATLOV: Stolyarchuk...
- We have barely enough steam as it is.

The turbine is going too slow for
the test to deliver any valid results.

- It's enough.
- And if we add more water,

- there will be even less...
- I said it's enough.

I know what I'm doing. Stolyarchuk.

Main Pump 4, connected.

We should warn Khodemchuk.
The pipes are gonna be...

Never mind him. Kirschenbaum?

(ALARM SOUNDING)

The steam in the separator drum
is too low... five atmospheres.

All right, let's all help
him. Get it up as best you can.

(ALARM CONTINUING)

We should stop.

DYATLOV: Turn that fucking thing off.

- (ALARM STOPS)
- You have 15 minutes.

LEGASOV: Fifteen minutes.

They may as well have had 15 days.

The problem they were
facing was not solvable.

The power was too low,
the water was too high.

The test was already ruined.

The results would have been useless,

but Dyatlov didn't care.

All he wanted to do was
report a completed test.

1:22 a.m.

Less than two minutes remain.

Yuvchenko, a mechanical
engineer, is in his office.

Perevozchenko, reactor section foreman,

is in the refueling hall,

high above the 1,000-ton
steel reactor cover.

- (RUMBLING)
- Degtaryenko and Khodemchuk,

circulation operators,
are in the pump room.

None of them have been told

about the test.

None of them know what
is about to happen.

At 1:22 and 30 seconds,

Toptunov sees a report

from the reactor's
SKALA computer system.

Based on the absence of
sufficient control rods,

the computer is recommending
that the reactor be shut down.

Well, of course it's saying that.

It doesn't know we're running a test.

All right, comrades.

Another few minutes,
it will all be over.

Kirschenbaum, when you're ready.

We did everything right.

KIRSCHENBAUM: Oscillograph on.

Closing Number 8 throttle valve.

STOLYARCHUK: Generator
rotor beginning rundown.

LEGASOV: 1:23 and four seconds.

With every decision,

they have pulled this
reactor back like a slingshot,

further than anyone has ever pulled,

now the test begins.

The pumps are shut
down, and they've let go.

The pumps stop moving
water through the reactor.

Uranium fuel is now
unchecked by fresh coolant,

unchecked by control rods.

The balance immediately swings
in the opposite direction.

In less than a second,

reactivity increases.

Inside the core,

the remaining water is
quickly converting to steam.

A void is being created.

There is no fresh water to replace it.

Steam increases reactivity,

increases heat, increases steam,

increases reactivity.

The remaining xenon decays away.

The power is rising.

There's nothing left to stop it.

1:23 and 35 seconds.

We have a power surge! Sasha!

What did you do?!

1:23 and 40 seconds.

In every control room of every
nuclear reactor in the world,

there is a button with
one single purpose...

to "scram," or instantly
shut down, the reaction.

In Soviet reactors, that
button is called AZ-5.

You press AZ-5, all of the
control rods insert at once,

and the reaction is stopped dead.

But...

(SIGHS)

What are you waiting for,
Legasov? Tell your lies.

KADNIKOV: Comrade Dyatlov,
you will not be warned again.

- DYATLOV: Or what?
- For god's sake, Dyatlov.

Legasov's already given it away.

He said before, there was no
way to avoid what was coming.

- He knows something. She knows something.
- Comrade Dyatlov.

DYATLOV: I know what you
are, Valery Alexeyevich.

- You're a liar.
- We've heard enough for today.

- (MURMURING)
- The defendants will be remanded in custody.

- Court will...
- I... I haven't finished.

I still have more evidence to give.

It's not necessary. Your
testimony is concluded.

- Your Honor.
- Court is now adjourned.

- We will resume tomorrow with...
- SHCHERBINA: Let him finish.

(CHAIR CLATTERS)

KADNIKOV: Comrade Shcherbina...

Let him finish.

Dyatlov broke every rule we have.

(SIGHS)

He pushed a reactor to
the brink of destruction.

He did these things believing
there was a failsafe.

AZ-5, a simple button
to shut it all down.

But in the circumstances
he created, there wasn't.

The shutdown system had a fatal flaw.

At 1:23:40, Akimov engages AZ-5.

(ALARM BUZZES)

The fully-withdrawn control rods

begin moving back into the reactor.

These rods are made of boron,
which reduces reactivity,

but not their tips.

The tips are made of graphite,
which accelerates reactivity.

KADNIKOV: Why?

LEGASOV: Why?

For the same reason our reactors

do not have containment
buildings around them,

like those in the West.

For the same reason we don't use

properly enriched fuel in our cores.

For the same reason
we are the only nation

that builds water-cooled,
graphite-moderated reactors

with a positive void coefficient.

It's cheaper.

(CROWD MURMURING)

(CLEARS THROAT) The first part
of the rods that enter the core

are the graphite tips.

And when they do, the
reaction in the core,

which had been rising, skyrockets.

Every last molecule of liquid water

instantly converts to steam,

which expands and ruptures a
series of fuel rod channels.

The control rods in those
channels can move no further.

The graphite tips are fixed in position,

endlessly accelerating the reaction.

Chernobyl Reactor 4
is now a nuclear bomb.

1:23:42.

Perevozchenko looks down

- on the enormous steel lid of the reactor...
- (LOUD RUMBLING)

...and sees the impossible.

The control rod and fuel channel caps,

which each weigh 350 kilograms,

are jumping up and down.

He runs to warn the control room.

But there's nothing he can
do to stop what is coming.

1:23 and 44 seconds.

- (ALARMS BUZZING)
- The steam blows more fuel channels apart.

We do not know how high the power went.

We only know the final reading.

Reactor 4,

designed to operate at 3200 megawatts,

went beyond 33,000.

The pressure inside the core
can no longer be held back.

At long last, we have
arrived. 1:23:45, explosion.

In the instant the lid is thrown
off the reactor, oxygen rushes in.

It combines with hydrogen
and super-heated graphite.

The chain of disaster is now complete.

AKIMOV (MUFFLED): Comrade Dyatlov!

Comrade Dyatlov!

(NO AUDIBLE DIALOGUE)

LEGASOV: No one in the
room that night knew

the shutdown button
could act as a detonator.

They didn't know it,

because it was kept from them.

KADNIKOV: Comrade Legasov,
you're contradicting

your own testimony in Vienna.

My testimony in Vienna was a lie.

- (CROWD MURMURING)
- I lied to the world.

I'm not the only one
who kept this secret.

There are many.

We were following orders,

from the KGB, from
the Central Committee.

And right now, there are 16
reactors in the Soviet Union

with the same fatal flaw.

Three of them are still running

less than 20 kilometers
away at Chernobyl.

Professor Legasov, if you mean
to suggest the Soviet State

is somehow responsible
for what happened,

then I must warn you, you are
treading on dangerous ground.

I've already trod on dangerous ground.

We're on dangerous ground right now,

because of our secrets and our lies.

They're practically what define us.

When the truth offends, we lie and lie

until we can no longer
remember it is even there.

But it is still there.

Every lie we tell incurs
a debt to the truth.

Sooner or later, that debt is paid.

That is how an RBMK
reactor core explodes.

Lies.

Valery Alexeyevich Legasov,

son of Alexei Legasov,

Head of Ideological
Compliance, Central Committee.

Do you know what your father did there?

Yes.

As a student, you had a
leadership position in Komsomol.

Communist Youth, correct?

- You already know.
- Answer the question.

Yes.

At the Kuchartov Institute,

you were the Communist Party secretary.

In the position, you limited

the promotion of Jewish scientists.

Yes.

To curry favor with Kremlin officials.

You're one of us, Legasov.

I can do anything I want with you.

But what I want most is
for you to know that I know.

You're not brave.

You're not heroic.

You're just a dying
man who forgot himself.

I know who I am, and
I know what I've done.

In a just world, I'd
be shot for my lies,

but not for this, not for the truth.

Scientists...

and your idiot obsessions with reasons.

When the bullet hits your skull,

what will it matter why?

No one's getting shot, Legasov.

The whole world saw you in Vienna.

It would be embarrassing
to kill you now.

And for what?

Your testimony today will
not be accepted by the State.

It will not be
disseminated in the press.

It never happened.

No, you will live,

however long you have,

but not as a scientist, not anymore.

You'll keep your title and your office,

but no duties, no authority, no friends.

No one will talk to you.

No one will listen to you.

Other men, lesser men,

will receive credit for
the things you have done.

Your legacy is now their legacy.

You'll live long enough to see that.

What role did Shcherbina play in this?

None.

He didn't know what I was gonna say.

What role did Khomyuk play in this?

None.

She didn't know either.

After all you've said and done today,

it would be curious if you
chose this moment to lie.

I would think a man of your experience

would know a lie when he hears one.

You will not meet or communicate

with either one of them ever again.

You will not communicate with anyone

about Chernobyl ever again.

You will remain so immaterial
to the world around you

that when you finally do die,

it will be exceedingly hard to
know that you ever lived at all.

What if I refuse?

Why worry about something
that isn't going to happen?

(SCOFFS)

"Why worry about something
that isn't going to happen?"

Oh, that's perfect.

They should put that on our money.

(CAR ENGINE STARTING)

LEGASOV (ON TAPE): To be
a scientist is to be naive.

We are so focused on
our search for truth,

we fail to consider how few
actually want us to find it.

But it is always there,
whether we see it or not,

whether we choose to or not.

The truth doesn't care
about our needs or wants.

It doesn't care about our governments,

our ideologies, our religions.

It will lie in wait for all time.

And this, at last, is
the gift of Chernobyl.

Where I once would
fear the cost of truth,

now I only ask:

What is the cost of lies?
