@Dean And if it stresses the concrete enough to create fissures, we're looking at potential pathways of egress

@Dean In steel buildings the steel framework can act as a conductor of heat in a fire and actually slump. If the rebar conducts the heat to the point it melts would it then have a swiss cheese network of holes?

@lillymunster : on the other hand, this could split up the corium and therefore more surface and better cooling.

@lillymunster exactly what I was picturing

In my minds eye I could see the rebar heating and melting locally but not melting such that holes are made all over the concrete... remember the concrete is under the earth and would be somewhat cooler than that above ground.. it would actually act as a heat sink.. I kind of think localized affects on the concrete as far as cracking spalling and some break up

@Dean So because of the heat sink of the concrete and the cooling contribution of the rebars, the corium would likely cool and crust rather than flow in a highly fluid manner, correct ?

by Reed 6/10/2011 2:07:55 AM

@Reed that's what I invision, also, the wiki write up for the corium at chernobyl identifies different kinds of corium and discusses more detail on interaction and behavior of the specific types
by Dean 6/10/2011 2:11:54 AM

@Dean Thank you. The wiki information is good, and there's also the pdfs that Rbeaner posted earlier about corium reactions. They're good at illustrating its possible behaviors.

U.S. Nuclear Groups Set Post-Japan Study
www.bloomberg.com
"The Nuclear Energy Institute, the Electric Power Research Institute and the Institute of Nuclear Power Operations introduced the panel yesterday. The 12-member committee will “learn the lessons” from Japan’s nuclear crisis, which began three months ago tomorrow, and “apply them at our plants...”
"The industry-led panel is “laughable” and U.S. officials shouldn’t give any weight to its findings, said Damon Moglen, a climate and energy project director for Friends of the Earth, a Washington-based group that opposes nuclear power."

After Nuclear Crisis, Japan’s Biggest Utility Faces Insolvency Risk
www.nytimes.com
"“Investors used to think, ‘This is a utility. What’s the government going to do, let it fail and let Tokyo go without power?’ ” said Yasuhide Yajima, the senior economist at the NLI Research Institute, an arm of Nippon Life Insurance. “But now their confidence is completely shaken,” he said. “They’re racing to offload their holdings before the share price hits zero.”
A government plan drawn up last month places no limit on the company’s liabilities, even though Japanese law would allow for such a cap following natural disasters. But the plan, which must still be approved by a divided Parliament, also calls for a fund that would use taxpayer money to help Tokyo Electric compensate victims and continue to provide Tokyo with power, while avoiding insolvency. Under the plan, the company will eventually pay back the fund in full."

@Reed Oh I am sure that study will be completely unbiased. :-)

@lillymunster ;) That's why I included the "laughable" line in the post. :)

1,700 kids living 20-30 km from N-plant
www.yomiuri.co.jp
"To cope with the increase in the number of children returning, the government has been using 20 buses to take children to and from seven primary and middle schools in the city's Kashima district, which is located outside the designated area. The service started April 22.
The measure appears to show that the local government is tacitly approving the presence of children in the zone. A local government official said: "Most of the parents who've come back to the district are engaged in work related to reconstruction, so we want to support them as much as possible. With this many children in the district, we have to be practical."

Radioactive Tea: Shizuoka Government Told Online Food Grocer Not to Publish the Test Result for Tea on Their Website
"The grocer is "Radish Boya" (Minato-ku, Tokyo) that does home delivery service of organic vegetables to its members. The grocer informed the Shizuoka prefectural government on June 6 that the Shizuoka tea they tested exceeded the provisional limit for radioactive materials in teas. Upon being alerted, the Shizuoka government demanded the grocer withhold the information and not publish it on the grocer's website. Accordingly, the grocer sent out letters to the members who bought the tea explaining the reason for the recall.
The Economy and Industry Division of the Shizuoka prefectural government explains, "We're doing the minimum that's necessary to alert the consumers. If the information is published on a website, it may spread unnecessary fear."

Analysis: Risks too great for full Japan nuclear shutdown
"Companies will put up with (power shortages) this summer, but if this goes on next year and beyond, they won't be able to come up with business plans. That's the worst-case scenario that needs to be avoided and the trade ministry understands this."
Japan on Tuesday pledged to overhaul regulation of nuclear power, saying that lax oversight and standards had contributed to the worst nuclear accident since Chernobyl in 1986.
Local government officials have been waiting for new safety standards to be implemented before approving a restart of the remaining reactors.

Special Report: After Japan, where's the next nuclear weak link?
www.reuters.com
"Imagine a country where corruption is rampant, infrastructure is very poor, or the quality of security is in question. Now what if that country built a nuclear power plant?
It may sound alarming but that is what could happen in many developing countries which are either building nuclear power plants or considering doing so - a prospect that raises serious questions after Japan's experience handling a nuclear crisis."

U.S. extends travel alert around Fukushima power plant till Aug. 15

Stars and Stripes coverage of the disaster in Japan

TOKYO — The U.S. government has extended a warning to U.S. citizens to keep out of a 50-mile evacuation zone surrounding the damaged Fukushima Dai-ichi nuclear power plant.

The alert, which expires Aug. 15 and was transmitted Thursday by the U.S. Embassy in Tokyo, advises that, although the situation at the Fukushima plant remains serious and dynamic, it is not a significant risk to U.S. citizens outside the evacuation zone.

“Out of an abundance of caution, we continue to recommend that U.S. citizens avoid travel to destinations within the 50-mile evacuation zone" of the plant, the alert said. “U.S. citizens who are still within this zone should evacuate or shelter in place.”

For the same area, the Japanese government’s evacuation zone is 12 miles.

Transport routes between Tokyo and Sendai that run through the zone are open to the public and the U.S. government believes health and safety risks associated with using the routes are low, the alert said.

“It is safe for U.S. citizens to use the Tohoku Shinkansen railway and Tohoku Expressway to transit through the area,” the alert said.

@all Japanese government releases first detailed English translation of plutonium holdings report
In response to a request from Citizens' Nuclear Information Center (CNIC) , for the first time the Japanese government has published a detailed English translation of its plutonium holdings report (as at 31 December 2006). The data includes input-output balance sheets. The latest report includes data for the Rokkasho Reprocessing Plant for the first time. Active testing using spent fuel began at Rokkasho on 31 March 2006 and the first plutonium-uranium mixed oxide product (MOX) was produced on 16 November 2006.

@Reed thanks for link to Woods Hole. Followed link there to IAEA – maybe this link on IAEA front page to “resourses in emergency” have been here all the time? I haven’t noticed. www.iaea.org There is a looong list of infobehind that link, one is: Method for Developing Arrangements for Response to a Nuclear or Radiological Emergency – a little late to start reading about HOW to plan for a nuc emergency… I hope March 11 made countries update their emergency plans – they should also remind the people how to be prepared, because not many are. Short, simple and true information about how to prepare. I think we should try to bring this up where we can, like on our blogs. That is not to make panic. I quote IAEA: “Emergency preparedness also helps to build confidence that an emergency response would be managed, controlled and co-ordinated effectively.” www-pub.iaea.org
