Don't panic. Yet.
Nuclear power stations are mostly non-flammable, and this one is said to be particularly sturdy. The cause of the fire is unknown. My hopeful 2AM guess is it could be a flare, or a molotov, or a small electrical fire, and that the fuel is still safely behind meters of concrete, and days/weeks away from a meltdown even if the cooling systems fail.

So the core will be theoretically flammable but hard to ignite if it's shut down as the report said.
Could still get some nasties released but hopefully on a small scale.
Hopefully.

I've been staring at a screen so long, stuff is moving about when it shouldn't and I spent 5mins watching a firefight only to realise it was snow falling past the camera.

and the smoke is out.
Time for a smoke of my own, I think.

set to "Clicks & pops" with a probability of about 0.01 to 0.1%, into a resonator and/or convolution reverb with a suitable cavern or car park impulse...
...Is my guess.
...Though comparing them now, mine's lacking a hum and the resonance is wrong. Still, my effort took 10 minutes.
Hire me if you need urgent sound design that's about 80% acceptable.

once the control rods are in, it's safe, no?
i was shown around australia's only reactor a few years back, and the staff pointed out a big red button on the control room wall, which was all they needed to hit to stop the reaction cold

but you get a lot of short lived isotopes from fission products and things that have been activated by neutrons.
They give off a lot of heat as they decay so you need to have some sort of cooling for a while until they calm down.
Most modern designs are designed to do it passively, so they work even if there's a loss of power. Older ones often need electricity to keep some pumps running for a few weeks, which was the problem at Fukushima.
If you start blowing holes in them you will be releasing highly radioactive crap whether they are currently turned on or not.
Fortunately it's starting to look as though the shelling didn't actually make any holes in the reactor itself.

They're mostly concrete, which tends not to burn at all. It supposedly starts cracking at about 140c and its melting point is about 1500c.
