There is a lot of grey area between: the entire west coast will be uninhabitable and the ocean will dilute the radioactivity to a safe level.
No, there isn't. You really think that this will cause effects that will be felt around the world? I advise you to put down the kool-aid and research this topic. It's like the noise that the media made about the Gulf spill.
Tepco has not been accurate in releasing info. They have no current technology or equipment to deal with the two severely damaged reactors and are only working on the one reactor that had its roof damaged.
Yes, there is. The problem is the radioactive contamination, which prevents cleanup. You don't just walk in and scrape up corium. As the radiation is cleaned up, they will be able to defuel the reactors and remove the nuclear products.
There is no accurate measure of how much contaminated ground water is flowing into the ocean, and their plan is to someday freeze the ground down to a depth that will prevent groundwater flow. This is a serious pollution problem that is not being adequately addressed.
So what's your solution? Complain that others aren't doing enough? This is a huge disaster; and things don't just happen overnight.
Why are the designers, engineers and manufacturer not being held responsible?
Because they didn't screw up. Tepco did, by placing their generators lower than was recommended. The reactor design was safe and effective, and included adequate back-ups. If Tepco had listened to the designers and secured off-site power supplies, or place the generators better, they would have been able to maintain circulation in their reactors.
It is the height of stupidity to hold a designer and manufacturer responsible for something that wasn't their fault.
Was the site chosen because it was seaside with the idea that seawater could be used in the event of a disaster?
You know that land is at an absolute premium in Japan, right? There is only so many places you can build a huge facility like this.
There is no money to be made cleaning up a disaster so I forsee that tepco will continue to make attempts to mitigate the radiation until they can no longer hide the fact that they are unable to go any further, or another tsunami/earthquake strikes and they throw up their hands and again claim an act of nature caused the problem, not inadequate construction and poor site location
Nice use of emotionalism that is utterly lacking in facts. You have nothing to support your arguments except wide speculation.
