MICHAEL SHORT: We've actually got a special guest today.

It's Jake Hecla, one of the seniors at NSE

who's gone on to Chernobyl for the second time, just returned

went through all of the physics and intuition

And we left off on what does it look like today.

So Jake is going to tell you what does it look like today.

actually going to go over a bit of the reactor physics involved

I realize you guys have already covered this to some extent.

JAKE HECLA: Yes, also I am a little sick.

So I'm probably going to start coughing, apologies.

JAKE HECLA: I have heard that joke about eight times

JAKE HECLA: Yeah, all right, where is Chernobyl?

Come on, no, go the other way, the other way, yep.

I got when I said I'm going to go and visit Chernobyl is wait,

It's not entirely under Rebel control in that area.

Russian forces are built up all along that border.

it's certainly not a place to be spending

That said, Chernobyl is north of Kiev by about,

I don't know, let's see, 200, 250 kilometers.

So it's not completely out in the sticks, right.

Hopefully this gives you good sense of roughly where it is.

All right, so what is the Chernobyl nuclear power plant

There are two unfinished reactors, unit 5 and 6, that

Those were constructed in the 1970s and early 1980s.

Units 1 and 2 operated with some success--

for a number of years before the accident that happened in 1986.

show the, some of the incidents that I'll

talk about here a little bit later in the presentation.

But this just gives you a general idea of the layout.

So it's two separate buildings for units 1 and 2.

And then units 3 and 4 are in one building, all connected

turn the steam from the RBMK into power, r.

well, before the accident, this was one giant, not separated

So you could walk from one end to the other, theoretically.

An RBMK is a light water-cooled, graphite-moderated,

This means that it does not have a giant pressure vessel

like you would see in a VVER or an equivalent American

Well, building giant pressure vessels is very difficult.

If any of you've done research on manufacturing

that the equipment necessary to construct a reactor

pressure vessel is not actually something

In the Soviet times, it was very, very difficult

for the Soviet Union to produce such pressure vessels

individual channels that were their own pressure vessel,
