Sadly, nothing. In one of the many special reports yesterday, they asked if anything would change in Japan, considering that a meltdown would affect Tokyo if the winds are wrong (and given that currently nobody can say with certainty that a meltdown can be averted!), re: nuclear power (and keeping in mind that the power company running decades-old reactors already has a long history of scandals).
The answer of the reporter? No, the nuclear lobby is too strong.
You can see it already in the other threads on this very board: Our reactors are better than this! (Factual evidence not required or wanted, just knee-jerk jingoism). One doper put it that Chernobyl doesn’t count in discussions of nuclear power, it’s in alternate reality. Probably because under the Soviets, even the law of physics behave different, because only Soviets cut corners, not for-profit companies …
Question to those US dopers who are sure that their reactors are 100% safe by design: how many old-style reactors with outdated, unsafe design are still running? How many of those are over earthquake fault lines? How many reactors built in the 60s and 70s have had their shells re-inforced, and how many have cracking concrete because of age? How many old-style reactors have been grandfathered through the new security measures, instead of updating them? How many “incidents” have the companies running the old reactors reported last year/ last decade, and how many did really happen according to neutral inspections/ sources?
Will any of the above questions be honestly adressed by the pro-nuclear lobby or just handwaved away? The latter. Will the pro-nuclear lobby bribe a few politicans and do a public image campaign to snow the public, as usual? Sadly, yes. Will things continue, until you get your own GAU? Yes. Would a GAU on US soil change opinions? No, not even then.
