I hate to admit it, mainly because I have no suggestions on alternatives, but this series of events has pretty much turned me from being pro to anti nuclear power. At the outset of the situation there were a LOT of fists banging on tables and loud proclamations being made (some of them on GAF, even) about how this would NOT be another Chernobyl, period, and anyone who would even suggest otherwise, or even suggest a high level of concern, was an ignorant alarmist. There were declarations made about how primary containment at one of these reactors could "pretty much withstand an H-bomb" - and since then we've learned that primary containment has apparently failed on at least one reactor.
In the most literal sense, the fist-pounders were right - this isn't another Chernobyl in that there hasn't been (nor likely will be) a massive explosion of a reactor core, no shower of graphite, etc. But in the practical sense, IE - in real world speak, things are headed in a bad direction and any number of failsafes have not stopped this sequence of failures from continuing down the line. It's not "another Chernobyl" - in a sense it's already worse than that because rather than replaying a script that's been analyzed a million times over, it's a unique scenario with unique problems and there isn't much to fall back on in terms of confronting the problem with knowledge gleaned from Chernobyl. And that's what has largely turned my opinion around. Every time we encounter a failure at a nuclear plant, it's going to be something brand new. And that issue will be identified and fixed, and things will be OK until the next new problem comes along. In most applications that's acceptable to various degrees. But when you're dealing with atomic energy, you're playing God and you don't get do-overs. The weight of consequence versus benefit is way, way off balance. And the fulcrum is humanity, in that these are systems designed by human beings. There are inherent flaws because we are not omnipotent beings. Unless the leaking radiation mutates us INTO omnipotent beings, or unless we figure out a way to eliminate any possible risk of leaking dangerous levels of radiation into the environment, I just can't bring myself to continue to support nuclear power.
That said, like I already mentioned, what's the alternative? That's the really distressing thing...
