ROBERT SIEGEL, Host:
From NPR News, this is ALL THINGS CONSIDERED. I'm Robert Siegel.
MICHELE NORRIS, Host:
And I'm Michele Norris.
W: And joining us with the latest in this effort is NPR's Richard Harris. Richard, how's that operation going to get the water into those pools?
RICHARD HARRIS: Finally, the military brought in five water cannons and they are reporting that those trucks did manage to spray some water into one of the reactor buildings. They say they sprayed about 30 metric tons of water, which sounds like a lot. It's not that - but not really anything close to what they need. But it is better than nothing because there's not going to be enough to replenish those pools.
NORRIS: So, success is still outside of their grasp. What's the plan moving forward?
HARRIS: Well, officials say they are planning to resume those spraying operations this morning. It's clearly - this is Friday here. This is clearly a stop gap, though, because they really have to devise a better system to get water in these pools. They just have to move more water faster. And one way they are hoping they can do that is by restoring electricity to the power plants, so they can start using the pumps that are built into the power station.
NORRIS: And we're hearing that they might be able to restore electric power soon. What's going on with that?
HARRIS: And I should add that it is good to have power. It's essential to have electricity eventually at this plant, but that's not the whole thing. Apparently, the pumps in the plant have by now been gummed up with all the seawater that they have been using. So the utility says it will have to plumb in new pumps, essentially, to do some of the things they need to do.
NORRIS: Richard, let's take a step back. Up until now, every day seems to bring a new complication, a new explosion or fire or some other trouble. It sounds at least like the situation is not going downhill so rapidly. And I think we may have lost Richard. Richard, are you still with us on the line there?
HARRIS: I'm with you. Can you hear me?
NORRIS: I can hear you. I can hear you. We just had some trouble there on the line. Let me just repeat the question, if I can. I wanted you to take a step back.
HARRIS: I heard the question.
NORRIS: You heard the question. So it sounds like at least the situation is not going downhill so rapidly in the last 24 hours.
HARRIS: People can't get in there even long enough to, like, drag a hose and put a hose into place, which you would think, well, why don't they just put a hose in? And that's why it's just - it makes it very difficult to work there.
NORRIS: You know, it's difficult to ask these questions and to even think about it, but I have to ask about a worst-case scenario. How bad could this be?
HARRIS: Losing the water is not an automatic catastrophe, but it could be because the fuel is covered with this metal material called zirconium. And as the fuel continues to heat up, the zirconium can crack, hydrogen gas can evolve and trigger explosions. And that could spew large amounts of radiation into the air. That would, of course, contaminate the reactor site also, making work there even more difficult and it would be blown downwind.
NORRIS: That's NPR's Richard Harris. Richard, thank you very much.
HARRIS: OK, Michele.
