Mind. they're meant to be able to withstand plausible incidents, an airplane crash, for example. one thing we learned at the fukushima disaster is that it is not just the safety of the reanterreant reactor itself. the power supply was compromised, the cooling systems that usually keep the reactor and the fuel cool weren't able to operate and so the reactor core melted down. so there are -- these are complicated systems there is a lot that could go wrong. a meltdown here as you see on the map, this reactor is on the river. so really an ecological disaster if the radioactive material got into th...

The nature of operating a nuclear power plant safely is inconsistent with military operation. >> correct me if i'm wrong. i read that there will -- that pools of water with spent fuel rods at the zaporizhzhia power plant and is that your understanding as well and i would assume that in a -- if there is a fire fight going on, or bombs falling or shelling, if there are large pools of waters with spent fuel rods, that would be concerning. >> so every nuclear reactor has spent fuel pools right next door to the reactor core, where spent fuel that is no longer used for energy production is moved fro...

Reactor is the functioning of a cooling system of a reactor core. so, if you can imagine, it's -- it's a sort of big pool into which the fuel rods inserted, and it has to have a constant supply of cold water to keep that core -- um -- and that nuclear fuel at a certain temperature. and of course, that system relies on a supply of water. that supply of water depends on the functioning of the pumps that pump that water to the core and the pumps rely on electricity. uh, there are back-up electricity systems, should the main power grid go out. that's -- that's standard for every nuclear power plan...

Military. the russians have run into the sand effectively being held back in a number of locations, even in mariupol, which they fully surrounded in the southeast of the country. still being held back there by ukrainian forces. the more they've held back and more they've struck out towards civilians, we've seen that graphically in kharkiv and in kyiv, the capital. kate? >> sam, thank you so much. let's go to kyiv right now, just as sam was talking about, where russian forces are approaching the city from all directions. the uk said russia could be preparing for a fresh attack against the cap...

Some are publicly visible through the internet when the internet is available, so it has been possible to monitor a small number of the monitoring stations to reassure ourselves radiation levels haven't changed, and there is also the message which the iaea is giving out clearly, is there is no radiological issue at that site for the time being. issue at that site for the time beinu. ~ ., , ' . being. what is the difference between this _ being. what is the difference between this site, _ being. what is the difference between this site, which - being. what is the difference between this site, w...
