"At Chernobyl, the Soviets simply entombed the charred reactor in concrete after the deadly 1986 accident. But Japan has pledged to dismantle the Fukushima plant and decontaminate the surrounding countryside, which was home to about 160,000 people who were evacuated after accident." How much of this decision is simply about space? Russia is the largest country by area, with 21 people per square mile, while Japan is m…
What is the article talking about when they say "radiation-hardened materials"? What kind of materials might that be?

The smaller some piece of electronics is, the smaller the charges in there are, and the easier it is to introduce errors with ionizing radiation.
Does anyone know how they extract the molten fuel? Sounds like they will use more robots, but if it's taken this long just to get a robot to see the target, how on earth does a robot retrieve this stuff? Must be a career defining experience for these robotists, doing something that can really help an awful situation

Fundamentally, Chernobyl is a much larger (order of magnitude) event with 6 tons of radioactive material burned and released. Frankly, for all the coverage Fukushima gets, it's amazing that you rarely hear about the associated tsunami and the damage it caused... 22k direct casualties with 2.5k still missing, 230k people still displaced in 2015 with ~400k structures destroyed.

I'm possibly nitpicking here, but Chernobyl is not in Russia.
Earlier quoted context omitted.

Not but it was in the USSR at the time which many people incorrectly equate with Russia today. To me it's almost ok to say "Russia" when talking about things back then. So long as you don't say Chernobyl is in Russia today.

I don't know what they did in this particular instance, but basically there are two things you can do: shield, or in the case of electronics, use larger parts. The smaller some piece of electronics is, the smaller the charges in there are, and the easier it is to introduce errors with ionizing radiation.
(Some server Power cpus seem to run parallel in pairs, comparing the output at critical parts to detect cpu errors)
