Accidents at Japanese nuclear facilities over the past decade include (WISE/NIRS, 2002; WISE/NIRS, 2007; Schneider et al., 2007):
■Sodium leak at the Monju fast breeder in December 1995.
■Tokai reprocessing waste explosion in March 1997.
■In 1999, 50 tonnes of primary coolant leaked from a reactor at Tsuruga, leading to a sharp increase of radiation levels inside the reactor building.
■Following a criticality accident at a uranium conversion plant at Tokaimura in 1999, two people died and hundreds were irradiated.
■In 2001, a water pipe at Hamaoka-1 exploded, releasing radioactive steam into the containment building
■In 2002, 16 workers were irradiated after a water pipe leak at Hamaoka-2.
■On 9 August 2004, five workers were killed after a steam leak at the Mihama-3 nuclear power plant.
■At the Mihama nuclear power plant in Japan in 2005, a pipe failed due to erosion corrosion, resulting in the deaths of five workers and injuries to six more workers. It was later revealed that the pipe wall thickness of the failed pipe had not been checked since the plant went into operation in 1976.
■At the Kozloduy nuclear power plant in May 1998, the emergency core cooling system and spray system was without a water supply for 24 hours, contrary to license requirements. This event was categorized as INES Level 2 due to a serious reduction in defence-in-depth and the adverse safety culture of the plant executives and personnel.
In addition, earthquakes have effected several nuclear plants in Japan, the most serious being the major 2007 earthquake which led to the shutdown of all operating reactors at the Kashiwazaki-Kariwa Nuclear Power Plant in Niigata. Radiation releases included small leaks of radioactive liquids and the release of small quantities of radionuclides resulting from 400 drums of low-level nuclear waste which were knocked over by aftershocks, 40 losing their lids.
He says in 2003 reactors across the country had to be shut down after it emerged the Tokyo Electric Power Company (TEPCO) had hid accidents. They had to shut down 17 plants in 2003 because they'd been falsifying the records about what had been happening at them," he said.
As early as 1972, American regulators considered discontinuing GE's Mark 1 system, according to The New York Times. "Among the concerns cited was the smaller containment design, which was more susceptible to explosion and rupture from a buildup in hydrogen – a situation that may have unfolded at the Fukushima Daiichi plant," according to the article.
The ban idea was nixed because of the industry's preference for the design. Today in the US, 23 reactors at 16 locations still use the Mark 1 design, according to the antinuclear power Nuclear Information and Resource Service (pdf). The nonprofit has released documents dating back to 1972 on its website.

Looks like no one is interested but myself. But this looks like it can affect the USA to.
Well, I spent three weeks following that Fukushima story doggedly... then in the end I found out three things...
1) Except for a handful of people and those that live in the area... NO ONE CARES...
2) We are still here... 1000's of nuke tests (especially near my home town) medical radiation, space radiation, CME's, cell tower radiation, microwave radiation... etc etc.. and we are STILL HERE.. and world population is increasing exponentially
3) Radiation is good for you
