A: Hey there! Did you catch the news today?
B: No, what's up?

A: They're inviting media to watch a drone survey at the damaged Fukushima plant!
B: Really? What reactor are they looking at?

A: The No. 3 one. You know, where there's still about 880 tons of nuclear fuel debris.
B: Oh, wow! So they want to start cleaning it up in 2037 or later, right?

A: Yeah, that's the plan. But first, they're going to send small drones into the reactor vessel next month for a test run.
B: Intriguing! How big are these drones?

A: Only 13 by 12 centimeters! They'll go in through a utility hole and take videos of the floor and other parts.
B: That sounds tricky! I wonder how they avoid obstacles inside.

A: Good question! They practiced at a facility, avoiding pipes and such with their remote controls.
B: Fascinating! Did they find anything interesting during the practice?

A: Actually, they saw some lumps believed to be nuclear fuel debris on the floor before. But the upper part is still a mystery.
B: Hopefully, this first survey will give us more info! Sounds like they're preparing well.
