Thank you for the link, PS
I agree. And I'd give up my little spot of land if they would build nuclear power plant on it.russ_watters said:It, on its own, doesn't mean we shouldn't become like, say, France and get the vast majority of our power from nuclear. I remain happy to have a nuclear plant 5 miles from my house (caveat - there is virtually no earthquake or tsunami danger where I live).
My father's uncle sold the land he owned in Wiscasset so that Maine Yankee could be built, with the understanding that he could continue to graze his cattle on the unused property. He was very disappointed then the plant was de-commissioned instead of being re-built with new reactor, etc.dlgoff said:I agree.

the EDG failure makes me wonder if the real issue is one of inadequate maintenance.
rootX said:Thank you for posting those pictures. All these http://www.bbc.co.uk/news/world-asia-pacific-12725485" makes me wonder how weak we are before nature.

One can see the breakwaters. They just weren't high enough for the particular tsunami that hit. The before and after pictures on the oceanside of the plant are quite telling.DevilsAvocado said:Thanks PS, unbelievable, JUST UNBELIEVABLE!
The picture of Fukushima Power Plant looks "unreal"?? The area in front of the plant is ERASED?? Did they not build that breakwater to handle tsunamis??

Scandal
On August 29, 2002, the government of Japan revealed that TEPCO was guilty of false reporting in routine governmental inspection of its nuclear plants and systematic concealment of plant safety incidents. All seventeen of its boiling-water reactors were shut down for inspection as a result. TEPCO's chairman Hiroshi Araki, President Nobuya Minami, Vice-President Toshiaki Enomoto, as well as the advisers Shō Nasu and Gaishi Hiraiwa stept by September 30, 2002.[3], and the utility "eventually admitted to two hundred occasions over more than two decades between 1977 and 2002, involving the submission of false technical data to authorities".[4] Upon taking over leadership responsibilities, TEPCO's new president issued a public commitment that the company would take all the countermeasures necessary to prevent fraud and restore the nation's confidence. By the end of 2005, generation at suspended plants had been restarted, with government approval.
In 2007, however, the company announced to the public that an internal investigation had revealed a large number of unreported incidents. These included an unexpected unit criticality in 1978 and additional systematic false reporting, which hadn't been uncovered during the 2002 inquiry. Along with scandals at other Japanese electric companies, this failure to ensure corporate compliance resulted in strong public criticism of Japan's electric power industry and the nation's nuclear energy policy. Again the company made no effort to identify those responsible.
http://en.wikipedia.org/wiki/Fukushima_I_nuclear_incident#Reactor_unit_3
Unlike the other five reactor units, reactor 3 runs on mixed uranium and plutonium oxide, or MOX fuel, making it potentially more dangerous in an incident due to the neutronic effects of plutonium on the reactor and the carcinogenic effects in the event of release to the environment.
DevilsAvocado said:This is 'weird'... maybe because I’m layman... but for g*d’s sake we are talking 'simple' rocks and concrete...?
I don't know the specifics of Unit 1, particularly the order or sequence of events in the shutdown. According to the Wiki article cited: "HPCI is powered by steam from the reactor, and takes approximately 10 seconds to spin up from an initiating signal, and can deliver approximately 19,000 L/min (5,000 US gal/min) to the core at any core pressure above 6.8 atm (690 kPa, 100 psi)." It's not clear to me if that was an issue.DevilsAvocado said:Astronuc, do you know if BWR Mark I have http://en.wikipedia.org/wiki/Boilin...ems#Emergency_Core_Cooling_System_.28ECCS.29" (ECCS) that can be directly operated by steam and provide water without electrically driven pumps...?

While Nagatacho, Japan's political nerve centre, has united around the rescue and relief effort, criticism of the authorities' response is seeping through. A headline in the Asahi Shimbun blasted the government's "incoherent" crisis management strategy, accusing it of taking too long to release information about the problems at Fukushima nuclear plant and evacuate tens of thousands of people living nearby. "Every time they urged us to 'stay calm' without providing concrete data, they simply made people more anxious," the paper quoted an unidentified politician as saying.
The cost of the rescue, relief and recovery effort will be huge. Manufacturers have closed plants while the energy infrastructure, from closed or crippled nuclear plants to burning oil refineries, is so badly damaged that power companies have warned of sporadic electricity cuts in areas hundreds of miles from the epicentre.

It was a nice quiet corner of the world 50 years ago, except when outsiders (vacationers) came to town. When I lived there, there were about 200 people. The population would swell during holidays. I preferred it when out-of-towners weren't around. Yeah - that's selfish - but then I was only 2.nismaratwork said:@Astronuc: Beauty always seems to have a steep price eh?

Meanwhile - 407 earthquakes above mag 4 since the mag 7.2 at 02:45:20 on March 9!

hypatia said:Looks like they are keeping a eye on Shinmoedake as well. Eruptions are common in the area, but this volcano erupted in January 2011, the first major seismic activity on the mountain in 52 years.
I don't see how the fuel exposure at Unit 2 is necessarily worse than for Unit 1 or 3, however, that means they've had 3 loss of coolant accidents at 3 units. One is bad enough, three is just three times worse.fuzzyfelt said:I hope nismar's friend is ok, too.
Has there been mention of rod exposure here, yet?
e.g,
"The fuel rod exposure at Fukushima Daiichi number 2 reactor is potentially the most serious event so far at the plant.
A local government official confirmed the fuel rods were at one point largely, if not totally exposed; but we do not know for how long. "

DevilsAvocado said:With all due respect nismar, I have no idea what you are talking about?
It’s OK to talk about the "beautiful shore"? But NOT about the shortcomings in security, that could have prevented the catastrophe from ever happened?
That is WEIRD.
