Japan Raises Nuclear Plant Crisis Severity To 7
darkonc writes "Early Tuesday in Japan, the government decided to
raise the severity level of the accident to the maximum 7 on an international scale, up from the current 5 and matching that of the 1986 Chernobyl catastrophe. The government declared the level 7 emergency because it is now estimated that the crippled plant was emitting over 10,000 terabecquerels of radioactivity for a number of hours at the height of the nuclear incident. Previously, on Monday, the government had expanded the evacuation zone around the plant to include at least 6 cities up to 60 km away from the plant. These cities, outside of the current 20-30 km evacuation area, are now expected to exceed the 20 millisieverts/year limit on residual radiation established by International Commission on Radiological Protection and the International Atomic Energy Agency in the case of an emergency."
This crisis, bad as it is, is still just a drop in the bucket compared to what we may be doing to our atmosphere with coal. I'd take a world powered by nuclear any day. At least the problems with nuclear are local-ish.
I am broadly in favour of nuclear energy - in principle. In practice, I have faith in neither corporate compliance nor government monitoring. Neither entity is equipped, or motivated, to appropriately manage long term risk... and that means you can good as guarantee failures. Hysteria about nuclear contamination, IMHO, has made matters worse - encouraging officials to focus exclusively upon reassuring the public that there is "no risk" at the expense of a focus on restricting and mitigating the consequences of the (ultimately inevitable) eventual accident.
... you don't understand risk analysis
Are the anti-nuclear crowd going to drive their cars to the protest? After letting the TSA spend billions of dollars to trample their rights on the flight over there? And receiving a decent dose of radiation on that flight.
Tell me again about "risk analysis" and how good the average person is at it...
it's not hysteria going on here. really
Uhuh.
No sig today...
We expect the world population will be in decline by mid century, due to the liberation of women, access to birth control, etc. If given the option, women prefer having fewer children and investing more effort in each child. It follows that our overall world consumption could eventually be covered by reasonable usage of wind, wave, solar, and geothermal.
There are large wind turbines that power 500 homes already, for example. Yes, it'll require several ass wind turbines standing above every suburb to power both that suburb and the city, but hey the burb's always did suck anyways. Also, there is much faster technological progress on wind, wave, and solar than civilian nuclear because they exist at scales that human handle better.
Btw, aircraft, spacecraft, and ships are our only vehicles that fundamentally require high energy density. All our current car designs require high energy density too, but a ground level power standard for highways could solve that problem for electric cars.
Are you familiar with what most infrastructure projects look like after a couple decades in operation? Nuclear power simply doesn't give enough room for the inevitable screw ups. You simply cannot trust either governments or private enterprise to handle the task long term. You could mandate that the family of every power plant owner and worker lived inside the plant, but you'd still find people dangerously cutting corners.
There will for example be another Chernobyl coming down the line in Bulgaria's nuclear industry now that they're completely run by organized crime. ( see http://wlcentral.org/node/1568 http://wlcentral.org/node/1495 http://wlcentral.org/node/1488 ) Italy's mafiaa has also decided it wants some part of the nuclear power pie. Do you remember when the garbage was piling up in Naples?
