The International Atomic Energy Agency says that Iran has tripled its production of >20% enriched uranium in the past three months, while adding 2,600 new uranium centrifuges to its main enrichment facility in Natanz. The agency has not received a "satisfactory explanation" of how 20kg of uranium metal went missing from an Iranian research laboratory. Iran has been blocking IAEA inspections, and the agency "is unable to provide credible assurance about the absence of undeclared nuclear material and activities in Iran, and therefore to conclude that all nuclear material in Iran is in peaceful activities". In recent years, Russia and China have chosen to limit UN sanctions against Iran, whose government denies it aims to make atomic weapons.
After speaking with many senior Israeli leaders and chiefs of the military and the intelligence, I have come to believe that Israel will indeed strike Iran in 2012. Perhaps in the small and ever-diminishing window that is left, the United States will choose to intervene after all, but here, from the Israeli perspective, there is not much hope for that. Instead there is that peculiar Israeli mixture of fear — rooted in the sense that Israel is dependent on the tacit support of other nations to survive — and tenacity, the fierce conviction, right or wrong, that only the Israelis can ultimately defend themselves.
Fukushima: Inside the Reactor 2 Containment Vessel, 1/19/2012. Here are Mainichi Daily News and Japan Times reports.
The year was 1945. Two earthshaking events took place: the successful test at Alamogordo and the building of the first electronic computer. Their combined impact was to modify qualitatively the nature of global interactions between Russia and the West. No less perturbative were the changes wrought in all of academic research and in applied science. On a less grand scale these events brought about a [renaissance] of a mathematical technique known to the old guard as statistical sampling; in its new surroundings and owing to its nature, there was no denying its new name of the Monte Carlo method (PDF). -N. MetropolisConceptually talked about on MeFi previously, some basic Monte Carlo methods include the Inverse Transform Method (PDF) mentioned in the quoted paper, Acceptance-Rejection Sampling (PDFs 1,2), and integration with and without importance sampling (PDF).
MotherBoard TV: The Thorium Dream If, like many of the world's leaders, you are eager for a dependable and cheap energy source that doesn't spew toxins and greenhouse gases into the atmosphere -- and that doesn't result in terrible, billion dollar accidents -- you can end your search now. At least, that's the news from a tight-knit collective of energy blogs, dedicated to a common but relatively unknown metal called thorium. In the right kind of nuclear reactor, they say, thorium could power the world forever -- and without the problems that come with the nuclear energy we use today, from Fukushima-like meltdowns to the difficult by-products of plutonium that leave behind radioactive waste and weapons material. The idea certainly sounds like the stuff of fringe internet conspiracists, but it was actually born in the U.S. government's major atomic lab in the 1960s under the auspices of one of the country's most respected nuclear scientists, and the inventor of today's most common kind of nuclear technology, the light water reactor. - Thorium: World's Greatest Energy Breakthrough?

The IAEA report on Iran has been leaked to the public. But are the new allegations "a game changer"... or, even new, for that matter?
The B53 wasn’t just any old megabomb. It was the first bunker buster. U.S. nuclear doctrine called for it to be delivered over suspected underground Soviet command-and-control facilities. The dumb bomb wouldn’t destroy them so much as it would destroy everything remotely near it, leaving — literally — a smoldering crater. That was the U.S. plan for “victory” in a nuclear war right up until the implosion of the Soviet Empire. (related) [more inside]

The Cold War resulted in a rather large number of interesting military research programs. One of these with which I'm familiar is the Aircraft Nuclear Propulsion program, which ran from 1946 to 1961. The basic idea? Modify a bomber (such as a B-36 bomber), creating an aircraft that could theoretically remain aloft for weeks at a time without refueling, much like ballistic submarines? The challenge? Shielding. Shielding the reactor alone would make the aircraft prohibitively heavy, so the idea was to primarily shield the crew compartment instead of the reactor. However, to study the concept, and evaluate various lightweight shielding concepts, two very novel and unique nuclear reactors were built at Oak Ridge National Laboratory: the Bulk Shielding Reactor, a novel "swimming pool reactor", and the Tower Shielding Reactor, an unshielded reactor that was hung 200' in the air dangling between 310' steel towers. While the program successfully demonstrated several of the concepts (including a nuclear-powered gas turbine engine running in Idaho, and a modified B-36 that carried a nuclear reactor but wasn't propelled by it (mentioned above), the program was canceled in 1961 due to feasibility and budget concerns.

Steven Aftergood at the Federation of American Scientists presents Fifty Years of Space Nuclear Power "A plutonium fueled RTG that was deployed in 1965 by the CIA not in space but on a mountaintop in the Himalayas (to help monitor Chinese nuclear tests) continues to generate anxiety, not electricity, more than four decades after it was lost in place. See, most recently, "River Deep Mountain High" by Vinod K. Jose, The Caravan magazine, December 1, 2010." (MeFi previously)
In an effort to preserve the rich story behind this landmark film, CONELRAD has spent the last two years thoroughly researching DUCK AND COVER's production history as well as its initial public reception in 1952. Interviews were conducted with living participants involved in the making of the film as well as surviving family members of those key players who had passed away. In the course of our research, CONELRAD also uncovered a wealth of archival material that leaves no doubt that a tremendous amount of thought went into the making of this nine minute motion picture that has been the subject of so much dismissive ridicule over the years.

On June 7th the Fort Calhoun nuclear power plant in Nebraska briefly lost the ability to cool spent fuel rods after a fire at the site. The FAA issued a directive prohibiting aircraft from entering airspace in a two mile radius of the plant. Since last week the plant has been under a "notice of unusual event" because of the Missouri River flooding. Local news reports that the "facility is an island right now". The flight ban remains in effect. [more inside]

While not being an outright example of a clash of civilizations in the Huntingtonian sense, elements of cultural misunderstanding and fears about the system-challenging tendencies of Iran do aﬀect Western perceptions and inﬂuence Western behavior toward Iran. Furthermore, these kinds of reciprocal identity-based fears and projections of the other side’s presumed malevolent intentions tend to be mutually reinforcing. The risk is that they eventually become self-fulﬁlling prophecies.Iran and the West - Regional Interests and Global Controversies [PDF]. [more inside]

"All of us in the environment movement, in other words – whether we propose accomodation, radical downsizing or collapse – are lost." Is human civilization hitting the sustainability wall? If so, the environmental movement seems blocked about what to do about it, broods George Monbiot. Nobody likes a "steady state economy", and the worse things get, the harder that option is to achieve. Plus green contradictions might vitiate effective action: "the same worldview tells us that we must reduce emissions, defend our landscapes and resist both the state and big business. The four objectives are at odds." [more inside]

Even Japan’s infamous mafia groups are helping out with the relief efforts and showing a strain of civic duty. "The Kanagawa Block of the Inagawa-kai, has sent 70 trucks to the Ibaraki and Fukushima areas to drop off supplies in areas with high radiations levels. They didn't keep track of how many tons of supplies they moved. The Inagawa-kai as a whole has moved over 100 tons of supplies to the Tohoku region. They have been going into radiated areas without any protection or potassium iodide."
The first nuclear reactor was in Africa, 2 billion years ago. Two billion years ago, there was enough uranium 235 in a naturally occurring deposit in Africa to fuel a nuclear fission reaction. In 16 separate locations, spontaneously occurring fission reactions went on for some hundreds of thousands of years, cycling multiple times per day. A picture of Fossil Reactor 15.

Robots Guarding US Nuclear Stockpile "The US National Nuclear Security Administration recently announced that it has started using autonomous robot vehicles to patrol the vast desert surrounding its Nevada National Security Site (NNSS). The 1360+ square miles of territory is home to millions of tons of low grade nuclear waste, as well as Cold War Era nuclear weapons, and cutting edge nuclear testing research. Guarding those precious nuclear materials is the Mobile Detection Assessment Response System (MDARS) robot, which is essentially a camera on a mini-Hummer. The MDARS can roam and scout the desert on its own, alerting a remote operator when it encounters something that shouldn’t be there (two headed coyote?). Human controllers get real time video feed form the bot and can communicate with trespassers using speakers and a microphone. There’s just one MDARS robot on patrol now, but NNSA plans on adding two more in the next six months." Via: [Singularity Hub]
