"As usual, why don't we forget the OTHER costs you are not mentioning?"
This is indeed the problem. I am surprised at the breezy tone of this article, and the number of comments here that ignore this issue.
For example, the current cost to clean up Fukushima is projected at USD 112 billion. Thousands of people are still displaced and have not yet been compensated by the utility, TEPCO. Since the utility keeps fudging the extent of the problem, it is certain that the final clean up costs will be greater.
Before you sneer at the current release of radiation, keep in mind that there are trade partners that currently ban Japanese food products. Fourty-two countries and regions have imposed restrictions on food imports from Japan as a result of the nuclear accident (source: Japan's Ministry of Agriculture, Forestry and Fisheries). This means: Japan cannot simply restart the fishing industry in Tohoku while radioactive water is leaking into the ocean, saying "it's nothing". The market isn't buying. This is a major loss of revenue, of course. Hong Kong is the actually one of the top destinations for Japanese food exports, and it has a ban on products from the prefectures affected by the Fukushima disaster.
There is currently a debate in Japan about whether the utility can even handle the clean up job. Dale Klein, Former Chairman of the U.S. Nuclear Regulatory Commission, is now on the committee to monitor the clean up operation. Recently, he called them out in a public hearing, stating: "These actions indicate that you do not know what you’re doing, and that you do not have a plan, and you’re not doing all you can to protect the environment and the people."
This is not some green tree-hugger group getting hysterical. This is the head of the committee to monitor the current clean-up operation, a member of the nuclear village, part of an advisory body to TEPCO Board of Directors.
So, please, let's be realistic about the costs. The fact is, we don't know yet how costly the clean up at Fukushima will be. It will cost a lot, maybe even more. There are no simple solutions to this situation.
